Sounds like power supply board. easy fix..remove the back of TV take picture of the insides, and of the power supply board. jot down the part numbers off the board. do not remove till u get the replacement board. be careful back there even if it is unplugged u can get a shock. go to shopjimmy.com or amazon and look for a NEW board using the part # besure it is exact match..

SOURCE: Hitachi 55" Plasma HDTV, 1 yr old, suddenly lost picture and sound, but power light still on.

It sounds like a shutdown circuit is being activated. This is normal in cases where the power supply id drawing excessive current. I would suggest that you get this looked at by a qualified professional. This is because this problem may be in the power supply and the voltages can get dangerous in this section of the TV set.

In any event if this is a power supply problem chances are the technician will just have to replace the power supply. Which should cost from 150-250 dollars.

I hope this helps

if will tell you how to trouble shoot this tv. these tv's are known for two caps in the power supply to go bad and they need replaced then you have to test the sdr boards if they are bad you need replacement boards or you can send them off to be repaired. the link for the repair guy is on the page. this guy also sells the repair on ebay but if you contact him directly i beleave the price is lower. just tell him you were send over by home theater shack.

IGO tv connected with dish sound come from tv but pictur not show only blue color show


Component RCA Connectors are RED, BLUE, GREEN for picture. Sound is RED and WHITE. The red and white for sound work the same with the YELLOW that does picture. If the RED, BLUE, GREEN are in the wrong order you will get a blue or green picture. For the sound, try the other red and white connectors nearby. Make shore the right red connectors are connected correctly for sound or picture. Otherwise there could be a cable fault or a TV fault. If you get the picture right but not the sound, connect the sound into a stereo.

42LG5010 When switching the telly on the red light flashes then to blue light comes on to show we have power but no vision or sound


I would start by shining a torch at the screen when the TV is turned on and see if you can see a faint image in the background, if you can then this would more than likely be down to your inverter board/s
If not then if you have no picture and no sound at all then i would put this down to your main AV board (the one with the scarts and inputs on )
These guys have all boards for this TV
