Polaroid FLM 323b

Well, you need to find out if it is putting out the 24vdc for the backlights inverter board, if it does, then check to see if the 24vdc is at the inverter board, check the surface mounted fuses on the inverter board, check to see if it has BL_ON signal. One thing about bad caps, they can look normal and correct value but they can have high ESR which is bad for switching power supply circuits.

Capacitors kit: http://lcdalternatives.auctivacommerce.com/Default.aspx he can make you a set of caps.
Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

You can get the replacement power supply here for $118.

check the fuse

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.

Yes Tom I did and no it didn't help. I'm back to square one. Sorry!

Check the fuse first next to the cord on the TV

get new power module.

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.
