Re: Samsung LE37B650T2PXXN nearly white picture



No, the picture on my TV screen is not upside down - could be that I had my phone turned upside down and auto orientation within the picture was faulty. So you see it upside down in the image, but on my TV only the nearly white screen is an issue - the text is as expected. ...

Re: Samsung LE37B650T2PXXN nearly white picture

Thanks to everyone who replied to this thread so far!

To summarize it:[LIST][*]Cause seems to be a faulty AS15 chip (here: AS15-HF)[*]To be really sure, I should measure test points VG1 - VG22 (and for further helpful info VGH, VGL, V1D2, V3D3, HAVDD, AVDD, TP_B2D5V[/LIST]
So I ordered a few AS15-HFs, as it takes a while till they will be here after ordering and they nearly cost nothing.
Will do the measuring this evening and post the voltage of each of the Vxx pads.

Again: Thanks so much...

Hi everyone,
I'm completely new to TV repairs. While searching for the cause of the symptoms of my TV - having a nearly white picture whilst sound is fine - I stumbled upon this forum.

After seraching here and reading the related threads, I think my problem is related to the T-Con board.
I already ordered an "new" T-Con board via AliExpress, but the symptom is the same, after changing the T-Con board: still nearly white picture and sound is fine.
So either the cause for my issue is not the T-Con board or the "brand new" T-Con wasn't brand...

Re: New Members - please post your introductions here

Hello,
I stumbled upon this forum while searching for a repair possibility of my Samsung TV. I hope I can find an answer here. I'm an absolutley newby regarding repairing TVs, however I managed to solder a few PCBs for my Home Automation system, so I'm confident in being able to do the repair on my own - only I have no idea how to troubleshoot upfront...

Best,
Sascha

Cudos for the idea of having a new user leaving a message first before posting her own thread. I think this is very effective...
