JVC HD-56G786 While watching TV it just goes turns off and the Power LED and Lamp/Program LED blink rapidley simultaneously, i know from my research that means there is a problem with the lamp, tv was purchased in Feb 10,06 and I replaced the lamp in July 07,this problem started in Dec. 07, i sent the tv to a shop paid $600.00 and it still does the same thing, when it goes out after turning it on I just turn it back on and it seems to me once it has warmed itself up it stays on

It would be interesting to know what the $600 got you.
Many of these kinds of failures are attributable to power supply problems and depending on the design of the supply and knowledge of the repair tech, it may be a repetitive problem.
The only way to fix this permanently is via the detailed inspection of the circuit, replacement of the failed parts and often, the addition of certain components to provide some protection of the parts that will likely fail again. Replacing of the supply completely will probably only give you momentary relief until these parts (almost surely chemical (electrolytic) capacitors) before they again fail to perform their designated function.

Power led and lamp led blink simultaneously on my jvc hd65s998 rear projection tv


You might need to replace your lamp driver, or ballast as some call it. This is what strikes the lamp to make it light.

I have a JVC-HD projection TV model 56G786 and all of a sudden it will not power on. When you try to turn it on the blue light on the power button goes on but after a few seconds it starts flashing and...


Hi,

The JVC 56G786 users manual will not give you a clear or specific answer about confirming bulb failure with the LED lamp or power indicators located on the front of the TV.

If the TV was operating normally for an extended period of time (months or years) and will not start, the problem is almost always bulb failure. If the "Lamp Replacement" warning previously appeared "On-Screen" and the TV will not start, bulb has failed.

The first step in a "no picture" situation with a JVC LCD Rear Projection TV is bulb replacement. There is no way to measure the bulb. Sometimes the bulb is visibly broken or damaged when it fails. Remove the lamp cage and have a look.

The JVC Lamp Gallery has all the JVC models and lamp numbers listed. There is also a link to DIY JVC bulb and lamp installation.

If a good bulb is installed correctly and the TV still does not start, you need a technician. There are no user serviceable parts other than the bulb. Failure of ballasts, power supply boards or controller boards is rare in these TVs.

Please help!!! Problem with JVC DLP TV


You need to replace the power supply board. The new ones have a bigger heat sink - obviously JVC knows about the problem because they made the new ones bigger. It cost $250 from JVC and I installed it myself - took about 3 hours to do. If you are not tech savvy call a repairman. Hope this helps.

Please help!!! Problem with JVC DLP TV


Hi,
How old is your TV?
Lamps in DLP TV has specific working hours and physically lamp will look good but won't give light ( actually consume more current and protection circuit stops power supply)
Thank you.

TV won't turn on, possible lamp failure.


I would suggest, since you have some technical background, that you download the manual for your set.
This site seems to have the best prices of any around:
