If you have PLTV-32, check to see if your AC adapter is putting out the 24vdc for the backlight inverter, you are getting the 12vdc from the adapter for the sound and for the processor to turn on the TV, otherwise you may have backlight inverter board problems.

PLTV-32C has power supply module inside the TV: http://www.google.com/products?rlz=1T4GGIH_enUS282US283&q=pltv-32+power+supply&um=1&ie=UTF-8&ei=PWVvTOy6M5H4swOciO3DCw&sa=X&oi=product_result_group&ct=title&resnum=4&ved=0CCwQrQQwAw

No picture on TV


First place to look will be the power supply module, check the 5vdc standby voltage and all other voltages as well.

My proton LCD 32'' has sound but no pictures.


If you need a board write the board number down. Try LCDparts.net and see if you can match board with what they have.

I HAVE A PROTON LCD TV 26'' PLTV-26 HAS SOUND BUT NO PICTURE


Your power supply most likely has blown capacitors. Pull the back cover and look at your power supply. the bad capacitors will be bulged and/or leaking electrolytic fluid (don't worry its not going to be runny). You should be able to fix it for less than $15. Search youtube for lcd repair and for the parts the best deal I have found is Digi-Key.com. Its fairly simple and should fix your problem. Plasmas suffer the same issue. Hope this helps.

Get sound but no picture. All cables and wires seem to be secure. Don't know what the problem is.


It can either be the backlight inverter board or the power supply is not supply 24vdc to the inverter board.

PLTV 26 LCD TV sound-no picture


I would suggest to check the 24 volts from the power supply to the backlight inverter board. If the voltgage is missing or lower then 20 volts, the power supply is defective. If the voltage is correct, you might have a defective light inside the TV behind the screen since you've replaced the backlight inverter board; you now the failure is not there. The lights are connected to the backlight inverter board.
Let me know if you need further assistance.

Re: Protron LCD tv - READ THIS #631 I work for Protron.

We are in a big dispute with the Chinese factory that makes Protron LCDs. No replacement parts will be coming, ever.

There are no remotes and no power supplies available.

PROTON has already won their lawsuit which prevents us from selling under the name PROTRON. As soon as they pay the bond, we are shut down.

Our management is in chaos. Our customer service dept is non-existant. Our rating with the BBB is 'F'. The product is cheap because it is made with cheap parts. Getting the picture here?

If you buy a Protron LCD, you are completely on your own.

Good luck.
