Question about Proscan PS27123 TV
I have a 13 year old PS27123 - recently after my kids were playing on their WII they noticed that the picture had expanded about 10 to 20%. The edges of titles and menus are now off the screen - picture is okay and everything plays and sounds fine - picture is just expanded. No on-screen menu or remote control command or adjustment on the back of the set fixes it. I have taken the small panel off the back and tried adjusting the controls inside - no help.
This problem is called blooming, and it is caused by poor High Voltage Regulation. It usually denotes a problem in the HV section of the TV. More then likely the problem is in the IHVT (Integrated High Voltage Transformer).
I hope this helps,
