capacitors will look like they are bulging. total cost of parts around
five dollars. if you can use a soldering iron and have a half hour to
spare this will fix it .there are alot of polaroid customers that have had
this problem and fixed it themselves. just click on the follwing to see

Green/blue vertical lines, no pix, screeching


This is a cap problem too.There is a third 1000 microfarad cap near the other 2 I would suggest you replace while you are in there.The instructions are very good and if you follow them carefully it should be an easy repair.If you have a friend who does some electronics and are unsure of your ability it will be duck soup for anyone who can solder.

SCREECHING AUDIO


My Vizio (don't know model # off hand, 32" bought at WalMart in Jan), is doing the same thing. It did it once the day I set it up; thinking it was just a glitch or something about my lack of knowledge with HDTVs, I powered it off (the hard way, yanking the power cord, as it won't turn off any other way) and restarted it, everything seemed OK. It did it again around April, same thing, just a glitch I figured. I changed some cables, attached more devices, and it has been doing it about twice a week now.

Sometimes it is the full video lockup, with vertical green lines, and full blast audio screech. A couple times it has only partially locked up the video (green vert lines, but still some movement), and no audio screech. Did it last night most recently, hence my google search.

Anyway, my point is, this is probably more common than we were both thinking, and they know just from your description what the problem is. I would try to have them repair such a known-issue free of charge, even out of warranty.

Green vertical lines on the screen


Sounds like you may have some bad filter capacitors in the convergence board. Better take a close look at them before they damage the chips. Good Luck
