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 LCD sound but no picture. Changed out c32, c33, and c34 caps but it did not fix the problem. None of the other capacitors look bulged on the board. Any ideas where to go next?


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.

No Power to LCD Tv


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.

Polaroid FLM-323B nothing at all


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.
