Re: Samsung PS51D8005 no picture

Hi!

Just wanted to give an update. I've now installed a new main board and my TV is up and running again

Turned out that a yellow/brownish area behind the processor isn't an indicator of a burned out main board. Got a used main board from a TV with a broken panel, and the main board looked exactly the same.

So I no idea what happened to my main board, but that doesn't really matter Fixed a £1000 TV for only £40, couldn't be happier!

Thanks for all the good advice on this website. Hope people can use my experience for their own fixes

So after a few days of use my Y-sus blew up replaced it and had a working TV for 1-2 months. Then it just turned off one night all of a sudden. Completely dead I suspect that the main board is dead once again, but haven't investigated it further.
Is it normal that boards die like this after replacement?

Did you check all the voltages was as per the panel sticker after you carried out the repairs? i guess if was too high it may cause issues like this?

yeah, I did the check and they all match the sticker except from +/-0.5 V. Saw a youtube clip where they said that was fine, so thought it wouldn't cause any problems.

yes that should be fine im not sure what else can cause the issue of the blowing board unless when the ysus went it somehow damaged the mainboard but not sure how but do your tests etc and see if its defently a mainboard issue again.

Thanks for the pointers vinceroger69. For now I've decided to buy a new TV. However, I'll keep the old one for when I move from my apartment to a new house. Then I'll have more room to investigate
