I have a polaroid flm 323b. the tv is not powering on. i already changed the safety fuse on the back by the power cord, but still nothing, the stand-by light wont even come on. but it still sparks when i plug it in. can anyone plz help??

try finding a service center that repairs those sets. Or try ebay. Lots of TV parts there.

Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

I would suggest not to try to use the TV until the problem is solved becuase more damages can result.
Please post back what you find.

check the fuse

panel defective.caps only repair a power supply issue where the tv wont come on at all.
lines are 90% panel and 10% control pcb
connected to the panel.most control pcb are not
sold separate from the panel.

Even if caps do not look blow, they still can be. Check diodes and resistors on power board. Easy fix if you have patience and time. make sure you replace with a higher voltage, but same cap, resistance values.

Check and replace ALL high value electrolytic capacitors on the power supply board. The Polaroids have known issues with leaky caps in the power supply. It's best to just change them all to prevent future failures.

Check the fuse first next to the cord on the TV

The 2 1000mfd cap that are 10 volts should be replaced with 1000 mfd 16 volts at 105 deg. All the caps need to be high temp and high grade.

Polaroid FLM-323b No power,No led light, checked the fused and the fuse is good?
Can't find any bad Caps? Well I spent some time, well alot of time trying to figure out what's wrong and finally did.
The problem is a diode on the power board location Z9 Part # ( P6KE350A )On some boards it's the diode and the capacitor right next to it part # ( R 331K 1KV )
If this works Please donate Paypal [email protected] anything helps Ive spent well over a weeks time and count less hours trying to figure out what was wrong.I have included some pics to try and help.
Thanks Z28r2fast4u

FLM-323B same problem, black screen. Checked out the power board and there is no 24v on it. Took the board out, let it cool off, put it back in. Got my TV back for a while, checked for 24v and it is there. Worked for a few weeks, now it's out again. Known issue with Polaroid, and if it's out of warranty, might as well throw it away because they WILL NOT help you. Personally this was my first and LAST POLAROID TV ever, TOTAL JUNK.
