I have a JVC HD-52FA97 projection TV. After about 10 seconds after turning the TV on the red lamp light and blue power light start flashing together rapidly. i replaced the bulb yesterday. The TV sounds like it is turning on, but there is never a picture or sound. Any idea what is wrong/

Something went bye bye. Check out your power supply for bad, burned components and/or blown caps - the latter often explode in their death throes.

If lamp is bad set will detect that (or other issues) and kill all functions=not unusual to have no sound if lamp is bad.

The tv projection lamp has been inside tv about 2 years alredy?Yes.Time to replaced the tv projection lamp.The tv projection lamp life are over.

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.

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.

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.

I have a 61" JVC that just stoped working. I turn it on and nothing bu the blue light stays on and the red light blinks 8 times and then the blue light joins in.

Hi
Usually, if the red light is flashing and you get no picture, that means that the lamp life cycle is finished and you'll have to get a replacment lamp. the lamp has about 3000 hours of life (2 to 3 years under nomal use).

You can buy a replacment lamp from here
