Hello:

Yes is is your convergence IC's. One has gone bad, but consider replacing both of them because if one has gone bad then the other is not far behind. They are located on the middle board of your set. They are mounted on a large heatsink, the part # should be STK-392-040. Replace these and your set will work fine again.

PTH5498 Akai TV Concave on top and bottom


I just picked up the same tv for free, and have the same problem.
but mine also has shadows of blue and red everywhere. but yes, it is in fact a convergence problem.
you can buy the part to repair it yourself, but its not as easy as just plugging it in. you have to solder it, plus a resistor(if that blew too), and a fuse(again, if that blew as well).

tvrepairkits.com claims they can make a kit for any tv, i sent them an email to see if they can make one for the akai.
here is the part number for the convergence ic's STK392-040 if youd like to find them on your own.

A lot of people on this site have this problem, including me. Usually a problem in the convergence board, requiring fixing (not expensive, really) or replacement (about $80 DIY). In my case it was a coolant leak.
