I changed capacitor C926 (1000Uf 16V) on main board. It solved the problem. I went with 1000uF 63V as it was readily available...it's okay to go with higher voltage. It was hard to fit it on because of the larger size but it worked.

The infrared receiver light just keeps blinking red and TV won't power on. Tried unplugging for a little while but didn't help.


kindly count the blinking led to diagnose where the fault came from..

also try the initial check....open the back cover and inspect the power supply board for any bulged capacitors inside..

My JVC AV-48WP55 only blinks the green led when plugged in. This happened after a power surge, during a thunder storm.


Have you tried unplugging the tv and letting it sit for a while then plugging it back in?

also.. sometimes i have seen appliances that will flash the power light if an internal fuse has blown to indicate a problem. open it up if you feel you want to and check for a fuse around where the power cord comes in teh tv.

TV turned off itself and timer light (red) keeps blinking


The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Tv turns on and off


My JVC 35 " AV 35750 toggled on/off non-stop too.

Fix for me: Unplug TV. Trace cables from on/off switch to main circuit board. I unplugged the cable at that point to eliminate the the on/off button and remote control sensor. Applied power to the TV and my TV stopped cycling on/off so I figured the problem was probably not on the main circuit board but with the push button/ remote control sensor board. I again removed power from the TV and plugged the cable back in to the main circuit board. I then applied power back to my TV to verify my symptom, but when I did this, the TV worked fine again.

Many times resetting circuit board connectors will clear electrical problems.

POWER WON'T TURN ON . YES, POWER SUPPLY OUTLET IS GOOD


Replace capacitor C926 near center of circuit board chassis (label is on the bottom) by a 1000uF 50V. Mind the polarity!
