As far as I know the schematics are not available outside of authorized service centers. Since giving the set a whack appears to "fix" it, it suggests that there is a bad connection somewhere. I would look for poor solder connections. Resolder any that appear to be grainy or have cracks.

Let us know your progress.

TV turns on...displays Polaroid then shuts off. Sometimes i can't even get it to the Polaroid point just turns on and turns off.


You have a bad power supply, call a local tv repair man 2 fix it for ya. Unless you think you can do it urself, but recommended a professional takes a look, dont want to damage anything else in the tv or hurt urself

Disc will not eject.


Common cause for a disc not to eject is the loose belt from the motor to the gear that closes or opens the disc tray. You need a repair man to open it and change the belt.

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.

ok two things here, if it a realy old tv, check and see if it has a vert control knob that you will use to adj the vertical rolling.

are you on a cable box? if so bypass the box and plug the cable directly into the tv bypassing the box, if this works box bad get exchanged.

2nd if it is a new tv, try this, when putting you cable to the tv do it slowley and watch the tv, as the cable gets close to rf imput on tv dose the pix get clearer untill to cable is pluged in all the way? if so you have agc overload and the simplest way to fix this is get a antenuator, this is a small screw on device that will cut the siginal streght down and will stable you picture.
