    The color appears proper but then fades and gets a green hue. I have an Akai PT5492S , it is approximately four years old. I have tried nothing as of yet to remedy this.

I have a pth5498 when u plug it in tv doesn't come on just makes clicking noise no tubes light up or anything just sound and front power light....


There could be many items that can cause that symptom. However I always assume convergence on any rear projection which can easily be checked by unplugging the convergence amp board and then plugging in the set and press power , if the set powers up turn it back off, and you will know the convergence ICs and associated resistors on that board have failed. Although its easier to replace the board unless you have good soldering skills. I am pasting a pic of the board which is suspended above the main chassis just mark the wires then unplug the set from the wall first, but then unplug the wires from that board and then try powering up the set.if you need further assistance , respond to this same post slinteriors_21.jpg

Any colors R,G,B out of alignment the convergence board are dead.The tv convergencce board must have it 2 STK convergencce ICS,and some or all it resistors be replaced to solved the convergence problems.The shop will cost u $300-350 for parts and labors.

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.

Convergence adjustment


HELLO . it sound like you need to replace the convergence board or just the IC'S ON THE BOARD. IT WOULD BE CHEPER THAN THE HOLE BOARD. "GOOD LUCK"

Akai PTH5498


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.
