Re: Polaroid FLM-2632, Blue LED, no sound, no picture, no backlight, cannot turn off
seems a high price for a main board though? is this set 1080 or 720 resolution? for a 26inch set just seems a high price to pay here in the uk i wouldnt get much more for a fully working set.Comment

Re: Polaroid FLM-2632, Blue LED, no sound, no picture, no backlight, cannot turn off

Re: Polaroid FLM-2632, Blue LED, no sound, no picture, no backlight, cannot turn off
Probably, that was from the main board I was working with. otherwise, if I was the seller I would ask for the main board back if it was a known good board.
I will try the seller in CA. and see if they will take my offer for $30.Comment

Re: Polaroid FLM-2632, Blue LED, no sound, no picture, no backlight, cannot turn off
Thats the trouble with ebay for that seller to say dispose of the item seems strange like he had a idea it may of been faulty at least you can keep it for parts etc they always come in handy.Comment

Dottos vinceroger69. It would only come in handy for me if I knew what component(s) to replace on the main board otherwise, it is useless to me.Comment

Re: Polaroid FLM-2632, Blue LED, no sound, no picture, no backlight, cannot turn off
FYI: I'd received my replacement main board this afternoon from electroparts eBay seller.
At first I did not have much faith that this main board was going to work because of the flux paste on the board. but, it did. now, I just have to put the TV togather. thank you all for your help on this, especially to budm, and vinceroger69.Attached FilesComment

Re: Polaroid FLM-2632, Blue LED, no sound, no picture, no backlight, cannot turn off
I think the flux points to what needs to be replaced.Comment

Re: Polaroid FLM-2632, Blue LED, no sound, no picture, no backlight, cannot turn off
Thanks for the follow up glad its working now and yes does look like those two voltage regulators? have been changed for some reason maybe if someone else has this fault they should check these first just in case.Comment

1.8V (1117l-18) and 3.3V (1117l-33) series fixed output regulator.
You can test the DCV on all 3 pins with ref to the chassis GND to see what you get.Never stop learning

Hi, I have a Samsung UE50TU with:
- sound and backlight, but no picture
- when it arrived, it had a picture for a few seconds
- it keeps rebooting
- without ribbon cable between the two panel boards, it does not reboot but I have no picture
- without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
- when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.
- without cable between mainboard and lcd panel and with a jumpered... -
I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly ‘new' Tcon board this time, and... -
Hello everyone,
Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
Anyway I still fully expect that there has been something seriously damaged... -
Hi all
I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.
Symptom:
No picture no sound.
When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
No sound at all.
What I tried:
1. I tried unplugging the left or right ribbon... -
so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol! 
i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...
