Did you check the service manual troubleshooting guide yet. You can try disconnecting the power to the inverter board and see if it will stay on and have sound.

When I attempt to turn on the TV the green power light will stay on for about 2 seconds. Did system reset with paperclip, timer light flashed for 1 minute. Tried again with same result.


STANDARD ANSWER FOR THIS PROBLEM:

MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ONFOR A MOMENT AND GOES OFF.

PRESS AND HOLD "device" and "menu"buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix.

BEFORE YOU RATE THIS INFORMATION LET ME KNOW WHAT YOU FIND, i AM HERE TOP HELP.

The tv just turns off after about 5 seconds and won't stay on. i've used the system reset and unplugged it already. no power surge, lightning storm, etc. Ideas?


If reset does not cure it and if after about 70 seconds of unplugging set the green power light stops blinking, do this:

When power light comes on and goes off, on the front of the set press and hold both the menu and input buttons at the same time for at least 5 seconds and RELEASE both buttons.


Power light should blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it four more times.

Let me know what error code you find and if this told you something you did not know, rate this solution as very helpful as I do this here for free.

JVC tv i'art blinking timer


It is protecting you and itself with high probability.
Power supplies in modern electronic devices are designed to cycle if there is a fault in circuitry they are servicing and because of the design, also will not turn on completely if they are failing.

The older style of power supply was 'dumb' and unable to do this so could cause fires if the failure wasn't teh 'right' kind to blow the main fuse.

I agree with the manual; this is a job for a tech.
