Question about Polaroid FLM-3732 Television

1 Answer

Green/blue vertical lines, no pix, screeching

If it gets a picture, it's intermittent... screeches, then has green/blue vertical lines... Is mine a capacitor problem, too?

    I had the same symptoms,screeching in sound and picture breaking into lines.The caps were the problem.Don't worry about the 35volt vs.10 volt rating.Don't ever replace a cap with one that has a LOWER voltage rating OR a radically higher rating.For original 10 volt caps don't use 6 volt(they would probably blow up due to excess current leakage)and don't try to use 150 volt(over time they might do something called deforming that is peculiar to electrolytic caps.The 35 volt radio shack units will work just fine and are unlikely to give future problems.There is a third 1000 micrfarad cap not far from the other 2 that didn't look too good to me.I would suggest replacing that one while you are doing all the dissassembly to get to the others.

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.

My RCA is screeching


To install the color wheel, turn off and unplug the tv, take off the lower back casing (17 star type screws), remove the lamp door, remove the lower back casing. Look just left of the lamp you will see 3 smaller star type screws near a small circuit board (which is on the color wheel), remove those screws unplug cable from color wheel, unplug other end of 2nd cable from tv circuit board (just to the upper left nearest to the color wheel.

All you have to do is install the color wheel, plug in both cables, put the back on and place the lamp door back in its position, the lamp door pushes in a lillte blue lever which allows the lamp bulb to light up.

I'm in the process of doing the same myself on my RCA same model. Where did you buy the color wheel from?

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.
