Polaroid FLM-373B Television Problem: When I turn the t.v. on the red light goes from red to blue but the picture does not come on. To get the pic to come on I must unplug the power cord and replug then turn the t.v. on again. That's how it started. Next while still needing to use that same procedure to get a picture the picture became distorted in a small band across the screen. After that the picture got worse in stages until now it will not come on at all. Help.

The one color problem could be either your color wheel or your DMD board. The DMD board controls the colorwheel RPM in order to create the vibrant exact colors that you see. You also need to make sure the fuse is OK

You will require a technician for the same.

Thanks.

This is not my solution, but, some insight into your problem provided by an electrical engineer, maybe it will help you.

Out Sourced Answer:
I noticed that you asked this question previously and should already have the service manual. And that the manual was not able to help you resolve your problem. These Polaroid TVs don't have very good service information for us technicians. And we tend to avoid that brand whenever possible.
I know this won't help you solve your problem, but I wanted to explain why your having so much difficultly getting an answer. I don't think you're going to get any better help than what that service manual gives.

The TV is going in protect mode because it detects an internal problem, try leaving it unplugged for a longer time, let say one hour or two.

    Basically, what happens is that the TV does not start because it detects that there is an internal problem, such as a wrong voltage, a bad component, overheating etc.
    When you unplug power and restart it, you reset the internal circuit, and the TV will restart, not detecting the internal problem.
    As soon as the TV gets hot, after staying on for a while, the defective part start giving troubles, as the defective component (probably an IC, starts overheating).

    As already pointed by the other expert, from description, the digital processing board. can be cause for the problem, as you told us picture shrinks to a small band and you lose convergence after TV stays on for a while.

    However all the following parts can be involved.

    Parts involved can be

    Polaroid digital processing board.
    Polaroid replacement ballast.
    Polaroid Replacement LCD controller

Polaroid FLM-373b not turning on no light


The power board might have input power, but there might be no output power. Check and replace the main power regulator board.

My polaroid flm 3732 tv wont turn on. the red light turns blue then back to red when i try to turn it on.


Have you tried the capacitor replacement trick here: http://www.fixya.com/TipsAndTricks/ThreadView.aspx?thid=741402 ? Use the method described (two places - look at both) to open the back of your TV. Look on the upper board (the power supply - where the 110 vac goes) for damaged capacitors as witnessed by their bulging tops. If they look ok and nothing else on the board is obviously damaged, I would go ahead and replace the three capacitors there. Two located near the center top of the board are 1000 micro farad 10 vdc electrolytic and the other right below the first two near the center of the board (a bit larger) is 1000 micro farad 35 vdc. Replace them all with 1000 micro farad 35 vdc (or wvdc) electrolytic caps - you can buy them from Radio Shack for $1.50 or so each. This assumes that your FLM-3732 is similar to the FLM-373B that I have. Good Luck!

Polaroid FLM-3732 Television turns on then off


A common problem with this television is the power unit. Some of the capacitors go out on them within 2 years. You can buy a replacement power unit for about $150 or if you know how to use a soldering gun you can purchase the capacitors for about $5 and fix the unit yourself.

I just fixed my Polaroid 3732 and it cost me $3.49. I would push the power button and the standby light would come on but the picture would not appear. After I changed the capacitors it starts right up.
