Power supply is OK (indicator light does go on) but we have no picture; Can you tell us what connector cables we need for this model (PLTV 32; Model LU32A1A3) Thank you


PLTV-32 or 32C?
PLTV-32 uses AC adapter that puts out 12vdc (for sound and logic) and 24vdc for the backlights inverter board. Do you get sound?
PLTV-32C uses built-in power supply that usually has 24vdc failure due to bad caps or bad circuits.

Try this first:
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.

Hi have a protron and can't seem where the plug to connect it is can you please help me


You mean that you don't have the A/C cord running out the back? If not there is a small black hold in the back of the set that you have to plug this type of cord in, if you don't have try places like walmart, home depot, or any electronic store.

No prower to tv plug and outlet OK


PLTV-32 uses AC adapter tah puts oit 12 and 24vdc, the PLTV-32C uses internal power supply. You need to check the DC output of the AC adapter or go in side to check the power supply module.

Protron lcd tv getting no power


I have the same problem. I am told that I need a new power supply (adaptor) but from what I am reading on the Net, they are very rare and TV repairman told me he cannot find the part. I heard that Protron is out of business.

funny that no one's been able to help you, because I accidentally discovered that the power supply cord for my computer worked for my Protron PLTV-32C lcd...  not sure if your model is different in someway, but you may want to try the cord from your own PC first, 
and if it works.
