Hi gentlemen,

I am new on this forum and i need your help.
i have a plasma TV sony ke-p42m1 ..When cold, no problem.. everything goes well.
After a while, the screen starts flikkering and i have snow and lignes with different colors and screen flikkers!!!
It's ca be interpreted as a temp. problem.
That's why i removed the rear covers and placed a big fan to cool down the temp on the tv platines..
No way..problem stays on screen.
Do you have any idea?? :41:

Thanks in advance

Ciao

Hi,did you check the various voltages generated by the psu when the problem is present?are them stable?is the

sound ok?try to connect another tv by the scart plug and see what happens.first of all,as this one is quite

an old thing look for bulging caps on the psu and the y-sus board.good luck

itstallion:
Dear sir,

Thanks a lot for your answer.
Bulging caps are ok..no condensator exploded..
Sound is always ok ..with or without flikkering
With signal for the antenna or not , the rv starts to flikkers and fine horizontal lines appears on screen..
Do you have any drawing wher i can measure the PSU voltages??

Thanks in advance :08:

Ciao

Calling Belgium,

I have uploaded the KEP42M1 service manual to the Download section of this forum. Don't think it will be of much use, but you may care to cast an eye over it....................Bruce

Million of thanks Bruce..

Best regards from Belgium  :08:
