Polaroid FLM-3232 Television - Page 4 Questions & Answers
Picture black and has sound
Check the caps in the 24vdc power supply for the backlights inverter board and the backlight inverter board itself for shorted circuits.
It can also be the T-CON board.
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

My polaroid flm 3232 is
Same thing happened. I unplugged it and everything for a couple of days then turned it on. Went to the menu and put reset to default. The V chip was then activated. If that happens to you too try 8202.

Our Polaroid FLM 3232 has
I hate to say it, but it is prob the main board that went bad. (the board where all the inputs get plugged into) It is possible that it might be the power supply. One thing to check is to make sure you have 25v coming from the powersupply board to the connectors that plug into the main board. If you do have 24-25v than you will have to replace the main board. If not than the powersupply.

My television has a black line in the screen
hi all .ive had the same problem,a thick black line down
screen.sometimes it flickers from top to bottom and other permantly in
view.but i have solved it.forget your ic boards and taking apart tv.have
you got either a ps3 or wii connected to tv.if so unplug power lead
from socket and relocate in seperate socket.make sure the lead is
completely free of any other leads and you might just find this works.i
think the power lead creates some sort of frequency that the tv picks up
.good luck hope it works

Polaroid flm3232. No audio
2 possible causes and you must do a simple test for that - connect an player to an AV entry and see if you get sound.
1 - you don't get sound - in that case the problem is hardware: the audio amplifier chip has failed and will have to be replaced; this requires a very careful desoldering of the chip and its replacement with an identical one that will be very hard to find - it's better to leave that to a pro.
2 - you get sound - that means that the channel format and the audio settings got messed up; since i don't know what you did to get them this way and troubleshooting blindly is a sure way to get the situation worse, the easiest way is to do a full channel rescan.

TV has no sound. The screen is blue until I select
Blue screen means that no signal is received - the tv starts on an open AV entry or the image processor is incapable of detecting it. Then, for some unknown reason, the PIP is activated, the image on the right is the secondary one - the one without the sound.
First of all you should try to flip it = to put the image on the left - there is a button just for that right on the remote. Then press the PIP button to get out of it.
If you can't do that then the controller - part on the mainboard processor - is damaged and it can't be fixed. You will have to replace the entire mainboard and that will be expensive - around $250.
Because of the poor quality of this tv i don't think that it's worth fixing it, it will be cheaper in the end just to get a new one.

From power on, until about 20 minutes warm up,
There are several weak capacitors in your signal board. You may need to replace as many as 15 or 20 capacitors. You will need purchase a cap checker. Many cases say to replace the signal board. But with great caution and patience a TV tech can do this for you! The power supply board will need one or two capacitors checked and replaced. As for the signal board, yes this is where the problem lies.
