Re: Samsung Plasma 50 inch picture problem
No I don't see any Vscan test point on Y main
there is a box in the middle of the Y board which says UP with Vscan written below it and an arrow pointing down to the left but don't see a test point
The only other test points are Vs and Ve on the X mainLeave a comment:

Re: Samsung Plasma 50 inch picture problem
Sorry Tom, can see a test point for Ysc near bottom left hand corner of Y main which is testing as it should
On Y main top right (at power board connection) I have Vs and Vcc which are all testing as they should alsoLeave a comment:

Samsung Plasma 50 inch picture problem
SAMSUNG 50 INCH PLASMA PS50Q97HD
Before I ditch my TV which has Sound with no Picture problem I thought I would put a post out and see if there is any rescuing it. I have tried all the tests on the forum and also followed every link through to the help videos and still no joy
I had 4 capacitors on the PSU bulged so I replaced all 4 with higher voltage caps
Green light on Y sus board so ordered and swapped this, Buffer board top IC blown so swapped both Y buffer boards
I have tested every possible voltage and everything is testing as it should, i cannot find any cracks... -
