OK so my jvc av56wp74 will turn on with a green pic then turns off and the blue light in front blinks

the green is the reboot process and is normal.
the red light is an error code indicator.
count the blinks of the red light...it cant be 30 times (I think)
it will blink a sequence, pause, then do it again for a total of three times.
count carefully, it gives you three chances to catch the number it is blinking.

Ur tv have convergence problems,it dead.U must have soldering tools and know how to solders to fix the convergence problems.U must replaced 2 STK convergence ICS,and some or all it resistors.Tries websites like Tv repair World.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will cost u $300-350 for parts and labors.

AV56wp74? The power button blinking blue means the set is in shutdown----the most common reason for this in this set is one of the two convergence chips is shorted. The way I usually prove this is to remove rear cover and or front grill and examine convergence circuit located at the front of the set----Also--I will unplug the plug from that circuit board that goes to the TV's power supply---if the set turns on with the convergence circuit board unplugged from it---you know your trouble is one of the two chips---if this is the case both have to be replaced and the set adjusted.

if the noise is from inside the tv in the back,the high voltage transformer that feeds the anode for the rgb tubes,28000volts probably is arcing.

you need to change your trigger circuit

My tv wont turn on. It tries to turn on the green light lights up 3 times then nothing. what is wrong?

when in manual convergence hit the select bottom to change to blue. as of green i have no clue.

Your lamp is probably gone
