My screen is blank and the power button keeps flashing blue

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.

I do this here for free so if this has helped you give me a vote here. If you have questions or need help let me know.

Red lines all over the screen

this set(AV56wp74) was first made in 2003----if you use the remote for the set and go into the customer menu---select convergence----once there see if the red and blue will move left/right and up/down----if either color will not move in any one of these directions----you have a bad convergence IC--this set uses 2 of the STK-392-110 output ic chips---both need to be replaced and the set adjusted with the original JVC remote control. I hope this has been helpful.

JVC av56wp74 IC CHIP

you can get the replacement STK392-110 Ics and the JVC convergence resistor kit #1 at the following link which has the complete step by step instructions with pictures so you can easially do it yourself. You will need the resistors also as JVC will definately blow one or two resistors minimum when the Ics fail. Heres the link.

Converge problem how to fix JVC AV56wp74

There are two of the IC's in the tv. First things first, turn the tv off and unplug it. Wait a few minutes, then open up the back by unscrewing the screws in the back panel. Now slide out the wooden panel that divides the upper and lower part of the cabinet. You'll see some cards sticking out of the plastic input panel. Find the one for DVI (it's the furthest to the right and it's at the top). Unplug all of the cables that are attached to this board. If you look closely, on the top of this board (the edge facing the top of the tv) there is a tiny little square looking hole on it. Cover this with black electrical tape or something that will not allow light in. The reason we do this is because JVC made a booby trap that erases the eeprom if you try and operate the tv with the back off. If the sensor senses light when the tv is on, it will erase the eeprom. Ok well now that that's covered, the actual convergence board (the one with the two IC's) is the board in the very front of the tv. It's long and slim and you'll immediately be able to see the two IC chips. They are big black things with lots of pins and they are pushed up against heatsinks. Those are what you would want to replace. Now I've not taken the boards out before, but from the looks of things, all of the boards are on a big black plastic tray so you can take them all out at once. I don't know if you can get just the convergence board out very easily, but at least now you know where and what it is. I would seek further instruction from someone a bit more knowledgeable about taking the boards out, but that should give you enough to do until you find more help. Hope this helped!
