Question about Proscan PS27600 27" TV
The problem is from a board in the television.
The board is known as a t-con board.
Have a repairman replace the t-con board of the television and it will be okay once again.
NB: You can replace the television if you wish to. But if you get the t-con board replaced, it will be in good condition again.

Thanks in advance for choosing Fixya for assistance !
I would like to know , if possible , some clarifications about your
Proscan TV , before I present my possible solutions to your problem.
Could it be possible to have some details about your TV?
such as :
Is the picture on the raster of your TV clear enough to see , except
for the Vertical problems you are having ( previously ) ?
have the Techs, open up your TV ( " for days " ) and what part / s
have been checked or done?
Would you like to do it yourself, or just needed information to pass to
your techs, to help them ?
From your initial statements , it could be a cold solder joints on the
Vertical Circuits , a possibly electronic components to check or
replaced if needed.
And possibly be easier to tackle with the help of a Service Manual
which I can post later to further assist you.
We might as well check on the power supply output voltages first
before anything else, then we proceed to the Horizontal Def Circuits.
• have a check on Horizontal Output transistor, the
Flyback transformer and the surrounding components
And these is where it all starts ( Vertical included )
If these Horizontal Circuits particularly Flyback would oscillate
there is no reason we can't make a full raster on your screen.
