You need to replace the capacitors on the power supply. There is video on youtube on how to do it, when you take the back off, the cover for the electronic components and get to the actual electronics you will find 5 capacitors in the center of the black power supply.
You need to replace any capacitor that is bulging or leaking. I changed out the 1000uf 10V models with 1000uf 35V models from Radio Shack, and had to caniballize a old broken computer monitor for the 100uf 450V center capacitor.
Make sure you get the radial head capacitors, and it is really easy soldering work to remove and replace. I used a 30 Watt soldering iron and heated up the old solder until the capacitors would slide out, then resoldered the new ones in. The TV started and works like normal. Even the sound is louder

After about 30-60 minutes TV starts to hum and picture gets distorted, could this be the color wheel...???


Sounds like a sync problem due to color wheel speed. clean and lubricate color wheel motor with tiny amount of Z-Max lubricant (liquid Buckey balls, available at Wal-Mart), on each bearing. make sure wheel is free-wheeling and turns easily. Should cure problem. If the color wheel is in good shape, there is a power supply problem, which may be due to dried out electrolytic capacitors or a regulator that's failing. Troubleshooting or controller board replacement may be needed. Regards.

TV is approx. 10 years old. Picture has started


This is a model first made in 2001--when it does it go into the customer menu and select CONVERGENCE--what you are looking for is is red or blue skewed and will not adjust?


If this is the case I can tell you what is needed based on the model number you provided.

2 yr old polaroid tv won't turn on leave on 10 min. plug and unplug then sound comes on leave on 10 minutes plug if polaroid comes up picture will come up.


There is a slight possibility that the ballast is going out, because after a while you do get the image, and the Tv is not that old, which I'm guessing you haven't replaced the l;amp yet, because it's not even time to do it, unless you the Tv is on for a great amount of hours, if so replace the lamp first.

Buzzing sound coming from TV Speakers and any external speakers


Your model has all the audio and video circuits that are all within the Control Box unit which has to be replaced as a unit. You can get one at the following link. You would have to leave them a email as they dont list the polaroid Control boxes, But I know they have one for your model. Just click on the " contact Us" link and let them know the model number they respond quickly.

FLM-373B Polaroid tv will not come on. The blue light comes on and when you turn it off the red light shows up. The screen of the tv is black and no sound. Can you solve this problem without calling a...


Same problem here. Polaroid Tech Support says that it is the control box.

It is a little over a year old so it is out of warranty with Polaroid.

Except, I bought the two year plan when I bought it at Walmart. So I called them and they are sending me a box and a shipping label to mail it back for repair. I tried to tell tham that is a little big to mail but they insist. This should be fun.

Polaroid FLM-2601 power supply board


The part number is 6LM00220G0 and is priced at $80.54 at circuit city repair. It is easy to install once you remove the cover from the back of the TV and the housing for the power supply.
