you probably have some sort of overheating or short on the internal board - is it still on warranty? if so they will fix at no charge - if not, a local repair shop should be able to correct the problem but it may cost as much as $150

check for a shorted regulator in the power supply section and bad horizontal output transistor.

hi hmwpeg

• you may need a PC to TV Converter

like one of these:

instruction is on the web page.


• to enable on your laptop, set your JVC TV as secondary monitor.

• use the Catalyst control panel.


hope these helps


thanks for choosing Fixya for assistance

Check and replace the chroma IC.

Hello Jim O'Connell,
Welcome and thank you for using FixYa!
To answer your question: I would suggest having a television repair professional pull out the power supply board.
They will need to remove the board and check it for bad (cold) soldier joints, bad capacitors, and lastly, to use an Osilliscope to test the +5v and -5V transistors on the board. If they can't diagnose the board, they can use the part number to order and install a replacement for you. That should fix your issue.
Have a great day!

i chaged some flyback on that model. you can unsolder b+ of fbt and replace with a 75 watt bulb to see if power supply or fbt.

Good day sir, its a different issue, about the capacitor, for as long as your replacement part is correct, it will work, now, there are several things you should check, the I/O device that controls the inputs of the TV, usually an IC, check your schematic diagram to trace the fault. check also the line from the input 3 to the controller IC on your diagram. Measure the voltage across the IC Vcc to ground if the IC is getting the right power, Low voltage can be cause by faulty capacitors, on the power supply line, or the IC itself is faulty, Circuit analysis and voltage measurements are needed to trace the faulty part. hope this helps thanks.

check the horinzontal out transistors. call qualified personnel to fix.

The problem you describe is not really related to a timer function being set. The unit is in shutdown and the light is blinkng to let you know there is a problem.
There are several possible causes. the most common is a failure in the vertical deflection circuit due to a bad vertical IC and possibly a capacitor, zener diode and resistor.
