    Hello! I am always on a tight budget and my bigscreen (same model as being talked about here) just started spazzing out. Sounds like the convergence chip I have been reading about. I am somewhat tech abled so I ventured into the cabinet and found the convergence board and the chips desribed. I have found the chips all over the net from 5 bucks up to 50 for jvc branded ones. My question is, will any work such as the Sanyo branded ones I have found?



    Thanks in advance,



    John the Cop in Ok

    Oh I forgot to mention, The spazzing occurred in the snap of a finger while I was watching television. At first I thought that the program had changed to 3-D!

This is by far the easiest TV to replace the convergence ic's - you don't even have to take the back off! Remove the front panel by removing the screws on the back edges secured to the front to the cabinet,also remove the small screw behind the front control door - the front comes off - remove access panel,there you will see the convergence board right in front - unplug the connectors to the board - pull it out and replace the ic's (2)part# STK392-110. Also check for any burnt or discolored resistors near the ic's - they may need replacing

The red tube is not acting right. When you go to convergence, the red lines are not straight. They are concave, I think is how you would describe it.

You need to install a convergence repair kit. You can get the AV48WP30 convergence repair kit at www.tvrepairworld.com the kit contains the parts and the Cd with detailed photos with instructions.

Turns on then in 1 second right back off

IF THE SET SHUTS OFF CHECK TO SEE IF THE POWER LIGHT JUST BLINKS(MOST OF THESE THE LIGHT IS BLUE)

A constant blinking of the power light means usually a short-----

The most common cause for this in AV48wp30 is a short in the convergence circuit of the set.

Let me know if you have the constantly blinking power light and I can tell you an easy way to prove without replacing any parts if the convergence circuit is your problem.

If you have a convergence problem causing this I can tell you what parts are needed and where to get them and how to do the fix yourself.

If this information has helped you rate this solution as I do this here for free.
