If you were to log on to the manufacturer's web site, I think you will be pleasantly surprised as usually one is able to download, by model number, Customer Instruction Manuals, list of Dealers for spare part supplies as required.

Just Google the manufacturer's name and follow the links. Make certain you are directed to the manufacturer's web site as some search engines direct you to other sites and they charge for the information that is normally free of charge.

I hope this helps.

How do I fix backlight problem on JVC LT32D-500 TV. I want to know if it is perhaps a common problem with this model and it it is FET or transistor related.


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

Turns on immediately turns off


check for shorted component parts at power supply board like bridge type diode and FET transistor. if those are good, disconnect the connectors that supply going to inverter board and then turn on the tv unit if the light indicator at front panel stay and 24v supply doesn't drop which mean the inverter board was the problem of suddenly turn off.

Sat went out lost power. can not get tv to turn on. checked outlet (fine) sat powered up. no tv power.


When this happened it probably took out Q406 a switching field effect transistor on the power supply board along with F401 an 8 amp Slow Blow fuse. The FET will have to be soldered in if it is bad. If the fuse is blackened, it is almost certain that the FET is shorted as well.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

If the voltage is OK, the amp will likely need to be repaired. If that's the case, do you want to repair it yourself? This amp may not be easy to repair. If you are not interested in learning to do this type of work, you should pay to have it repaired. If you want to repair it yourself, I'll try to help you through it.
