Dell 1800FP Repair

SYMPTOM: NO POWER


PROBLEM:  ICE2AS01 CHIP (Current Mode PWM Controller 8-Pin PDIP)


SOLUTION: Replace ICE2as01 and re-solder diodes D903 and D906 in the secondary of power supply. The diodes are the two mounted to a heatsink. These are the reason the 2AS01 goes out in the first place. The solder joints on these two diodes breaks loose. If you don't solder them, the 2AS01 will go out again.

Going rounds with Samsung & CNET, Boise LCD prevails!




Summary: When I first started doing this job, I used to get pretty hot under the collar when it came to corporate ignorance and defective products. Now I don't. It's paid for my new home, 3 new cars, and put all three of my kids through college. 
Thanks Samsung! 
Keep up the lousy work!

Ok, I lied. I do make a living from it, but it's very tiny. And I still get peeved when I continue to see more and more posts added to the thread below, amongst many many others.

What does it take to get this kind of crap to stop? Americans are being blatantly ripped off, one by one. And we can't even stand united for long enough to create some noise and make some changes. Do "we the people" have any power anymore? Or is it just a facade, a comfortable farce we like to believe in?

I'm afraid it's just that. 

But I'd love to be proven wrong. 

email me if you want to see a change. 


If I get enough response, we'll get this snowball rolling.

OBJECTIVE: Keep US dollars in the US, instead of continuing to shell out more money for overpriced, under-guaranteed, poorly-manufactured, deviously-created-consumable-commodities of electronic devices made by our friends across the way.

Samsung LCD LNS5296D will not power-up.

by besito27 - 3/1/09 7:36 AM
Samsung model LNS5296DX/XAA Version SP01. Purchased January 2007. Unit will not power-up using any means (direct or remote). Ocurred one other time but eventually was able to power the unit using the remote. Currently, the blue stand-by light is lit, but television will not power-up. Tried unplugging for different lengths of time. Still NG. Pulled back cover to notice several small fuses within power board but unfamiliar with electronics and not equipped to troubleshoot. TV is 2 years old and had no other issues since purchase from Onecall.com. Suggestions beyond the usual repair call? How has Samsung handled this problem as it appears others have experienced similar issues? Samsung should honor warranty if some type of manufacturing defect has been identified. Thanks for your help.

besito27,

There's not a known issue I'm aware of, but you can call the service line to see if they know of anything. 800-SAMSUNG.

TV won't turn on
by wild4trout - 11/22/08 12:21 PM

I have the Samsung FP-T5084 50" Plasma tv. I went to turn it on the other day, and it wouldn't turn on. No clicking. No red power indicator light. Nothing. It was plugged into a power strip with other components, and they all work fine. I unplugged it for a while and then plugged it into a different outlet on the power bar, but it still won't turn on.

Power Cord
by wild4trout - 11/22/08 8:26 PM In reply to: Power Cord by Samsung_HD_Tech Samsung staff

Yes, I disonnected, and reconnected the power cord in the back of the TV. I also removed the plug from the outlet it was in, and plugged it into the other outlets on the power strip that are working for the other components. But the TV still won't turn on.

Power Supply?

Hi, I have the same TV with the identical problem. Just happened this morning. Do you have an update as to what your problem turned out to be or the solution??

Thanks!

Confused...

You have the same problem as that post?

It's possible that two televisions can experience the same symptom without it being a "known issue". That said, we can repair it (free of charge within warranty) through our service center.

Same issue

by ahelms10 - 3/20/09 12:01 PM In reply to: Confused... by Samsung_HD_Tech Samsung staff
I have a Samsung LN-S5296D 52" 1080p High definition LCD TV and I am facing the same issue.

When I first tried turning on the TV today the blue light was on, but the TV would not come on. After calling Samsung and following directions (unplug, try different outlet), the blue light went out and has not come back on and the TV still will not power on. Samsung referred me to a company whose phone rings busy.

Good 'ol customer service!

Have you ever wondered how many times these people have actually been helpful to someone calling in with a broken device. They act like it's not common place for these things to die. Unfortunately with todays standards and mass production shortcuts, electronics drop like flies!



So why the whole rediculous routine of:

"UNPLUG YOUR UNIT FROM THE WALL AND WAIT FOR 30 SECONDS. NOW PLUG YOUR UNIT BACK INTO THE WALL, MAKING SURE THAT YOU HAVE APPLIED AT LEAST TEN POUNDS OF PRESSURE WHILE INSERTING IT INTO THE RECEPTACLE.

NOW, CLOSE YOUR EYES AND REPEAT AFTER ME. 'IN THE NAME OF THE GREAT AND HOLY MASTER OF ALL THINGS ELECTRICAL, I COMMAND YOU TO ARISE FROM YOUR CURRENT STATE OF AFTER LIFE IN THE ABYSS OF THAT WHICH DOES NOT FUNCTION ANY LONGER. I COMMAND YOU! I COMMAND YOU!!...'

OK, NOW I'M GOING TO NEED YOU TO CROSS YOUR EYES AND PAT THE TOP OF YOUR HEAD WITH ONE HAND, WHILE RUBBING YOUR TUMMY WITH THE OTHER HAND.

HMM, THAT DIDN'T WORK EITHER HUH? WELL LET'S TRY THIS..."


Why do we have to go to sites like this or Fixya.com or BoiseLcd.com (plug) to get information on how to fix THEIR defective goods? The least they could do is maintain an open knowledge base for the support of their garbage when it dies on the day after the warranty expired. But instead we get to call up a bunch of clowns who are probably laughing at us as we do tricks for them.

"NOW HOLD THE UNIT'S BUTTON DOWN FOR 8.5 SECONDS. NO MORE, NO LESS..."



Now that I'm done whining, let's get to your TV. Unfortunately I don't have any past experience with this model, but I can tell you if you leave it unplugged from the wall for a while, you'll probably get it back to the blue LED light flashing when you plug it in again. Not that that's helpful to you.

So let me ask, is it an LCD panel TV, or LCD projected?

IE. if you lightly ran your fingers across the screen when it worked, did it look like the image was water under your finger tips?

I only ask because the two types of TV's have totally different types of guts inside them.

LCD Panel

Very funny, thanks Chris. I think the Samsung support lady was having a good time.

The TV is an LCD panel. I found some info here from others who have the same tv and have had similar problems:http://www.avsforum.com/avs-vb/showthread.php?t=733588&page=28

Sounds like fixing it is beyond my abilities.

Samsung LCD LNS5296D will not power-up.

by besito27 - 3/23/09 8:51 AM In reply to: also, by ahelms10
To make a long story short, Samsung has installed low quality/under voltage capacitors on several of their Power Supply Boards, leading to the no power issue experienced with the TV's. This to save a few pennies on a TV selling for thousands. I purchased mine in 2007. Samsung will not acknowledge this and only asks the infamous "did you purchase an extended warranty" question when asked about repair criteria. I replaced 5 blown capacitors on the power supply board and the TV has worked fine ever since. Samsung, please acknowledge their's a problem, and maybe we'll forgive you. This fact is posted on several sites throughout the internet.

Capacitors

by ahelms10 - 3/23/09 12:18 PM In reply to: Samsung LCD LNS5296D will not power-up. by besito27
The tech who fixed my television told me the same. He replaced 5 capacitors on the power supply with higher voltage capacitors (16) and all is well. Total cost was $290.

I probably won't go to the trouble of complaining to Samsung but it is unlikely to get my business again.

ATTN: BoiseLCD...

BoiseLCD,



Numerous posts of yours have been deleted as violations of the Cnet forum policies. These include three pure, blatant advertisements for your own business, five other replies that included prohibited links to your own business, and three posts that were insulting to Mr. Samsung. Such prohibited content will be deleted on sight, without warning. You are more than welcome to assist other members, but only in a courteous fashion and only for their benefit, not your own financial benefit.

John

Oh my. What a surprise! You've taken the side of Mr Samsung.

by BoiseLCD - 4/24/09 2:59 PM In reply to: ATTN: BoiseLCD... by John.Wilkinson Moderator

My posts were purely my opinions; and I stated them freely because I believe in freedom of speech.



Did I use profanity? Did I insult anyone on a personal level?
NO.
I was simply trying to get these people to wake up and resolve these issues. And if Samsung is insulted by what I said, they need to correct the issue and start taking care of their customers, not stiffle their voices.

I will be heard.

I'm going to post this entire thing everywhere I can. Let people see how you and Samsung handle issues.

I suggest you leave the content alone. I will edit anything you deem inappropriate. This issue needs to stay out on the table. To just simply delete everything is not right.

And If you want me to provide people with repair advice on your web site, why can't I post a link back to my own? You make it sound like I have evil intentions by trying to spread the word about my services. Of course I want to get my name out there. Why not?

Post 13 of 43

No, I took Cnet's side...


If you had read the forum policies and Cnet TOS, you would have known blatant advertising was prohibited, but either you never read them or made the conscious decision to violate them. In fact, in 4 of your 10 posts, you never offered to help the individuals here in the forums, instead telling the people asking for help that "You can purchase my repair service on my web site, , for $40." These forums are about helping others because they need help, without expecting something in return for your 'generosity.' If you care about helping others, then help, but if you want free ad space you have come to the wrong place.





Also, you are free to share your opinions, but do so without the sarcastic, derogatory comments. As Samsund_HD_Tech replied to you previously, those "references are counterproductive to the actual problems we're are solving here." As a professional in the same industry, you know that problems are best addressed by the presentation of evidence and proactive suggestions, not insinuations and ridicule. Showing the same respect you would expect be shown to you goes a long way.

John

Agreed.

I apologize for my sharp tongue. You're right, it won't help being sarcastic or ill tempered. I forget that sometimes.


(But it sure is fun!)

And I guess there's no sense in even complaining about my prior experiences with customer support. Even if I were to convince someone that there are way too many unsatisfied consumers out there today, what could be done about it? It's not up to any one person to change it. One person can't change it. We can only do our own part in making things a little better. Whining about the past won't help.

The world will turn, circuits will burn, and people will learn.

I'll just let things be.
