Make sure you try every code in the list for your JVC TV.
The codes for your Jumbo Universal Remote to control a JVC television are 013, 054, 055, 060, 065, 067, and 089.

To program your remote by entering a code, follow these steps:

1. Turn on your TV.
2. Press and hold the CODE SEARCH button for at least 3 seconds until the red LED lights up and stays lit.
3. Press the TV button on the remote so that the LED blinks once and then remains solid red.
4. Enter the first set of 3-digit codes from the list. The LED will blink once every keypress. After the 3rd digit, the red LED will turn off indicating that the code was recognized for the device. If the code was not compatible, the LED will flash several times and you need to return to step 2 to try that code again or to try the next code in the list.
   
5. After the LED has turned off, aim the remote at the TV and press ON/OFF. If the device turns off, you have used the correct code and the remote was successfully programed. If the device does not power off, return to step 2 and try again with the next code in the list.
   

To have the remote try each TV code it knows one at a time, follow these steps:

1. Turn on your TV.
2. Press and hold the CODE SEARCH button for at least 3 seconds until the red LED lights up and stays lit.
3. Press the TV button on the remote so that the LED blinks once and then remains solid red.
4. Press the ON/OFF button slowly and repeatedly until the TV turns off. The LED will blink once each time you press the ON/OFF button.
   
5. Once the TV turns off, press the ENTER button to store the code and the LED will turn off.
   

I hope that helps.

you need to change your trigger circuit

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.

Hi and welcome to FixYa,

Sorry but there could be a number of possibilities and the best diagnosis would be to perform voltage checks of critical boards and compare with known readings. Common problems could be as simple as cold solder or loose connections, thermal fuse of the cooling fan or the light engine in some models not necessarily what you have.

This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings.Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Good luck and Thank you for using FixYa.

I would agree with you on that the power board could be at fault. The best course of action would be to get the board/TV checked out professionally. It could be the dry joints, resistors or capacitors.
