Question about JVC LT Televison & Video

Open Question

When I switch on my new JVC LT-32D500 TV it has a series of flashing colours and patterns as display. The unit itself has no buttons and the only input it 'recognises' from the remote is on and off. I can see the light flash on the TV when I push other buttons in that it receives the signal, but it doesn't actually do anything, e.g go to menu or input etc.

You have entered a diagnostic colour test. With the TV powered on, hold the 'Menu' & 'Enter' together, then press the power button. Problem resolved

SOURCE: Remote's menu and input buttons, and television Input button not responding

well the problem sounds like it could be the IR sensor on the tv or somthing in that circut that is failing or the EPROM chip that controls : Vol up/down , Channel up/down , Power on/off ,Menu , Input selection , ect... is failing, thus this will trigger the protection circut to shut the tv down. this kind of a problem only gets worse and can dammage other components if not repaired soon so it will need testing to determine the exact cause

Hi , I have the same problem with my LT-42X688,so i called the service of my extended warranty provider . the TV technician just left and told me the motherboard is the problem. he said its the third one this week he has seen with the same symptoms. he ordered the motherboard and i've got to wait 5 to 7 work days before the part will be in . I will keep you posted when the guy will return.

"JVC LT-42X788 display fault..."

Hi Thomas.

Please pick one:

Power supply board (possibly a blown capacitor):
A TV-tech can repair at reasonable cost, less than a new set.

The main board itself has a control / display section fault:
A TV-tech can repair at reasonable cost, less than a new set.

The screen / panel is shot:
Beyond economical repair - renew set.

Hope this helps.

Press Mode button to select TV. Then press the Display button. Set the Display to Off (choices are Detailed Mode, Clock, Simple Mode and Off). Pressing Menu should turn off the Display at any time.

I had water damage in my wall an my power strip got wet. Now my Tv shuts itself off after I turn it on before the unit ever comes on. Then the blue led power indicator light flashes.... U hope this is a...


Does it flash in a pattern or does it constantly flash - like 7 flashes then pause then 7 flashes? Or is it constant without pauses? Are you using a new power strip? It could be two things 1. Power supply or 2. Main board. is my initial thoughts. Have you opened it up to check the fuses, caps etc? If the power suply voltages look good its probably the main board.

Thanks,
