I have an AKAI TV...Model Code #PT4250AX/SMS - Rear Projection TV. The TV was being used and a pop sound was heard and then the tv was black (no audio, no video). Now when you turn on the power the red...

My recommendation is to call a local svc co. Since you heard a pop, it could be anywhere in the set. It requires trouble shooting to isolate where the problem is. I hope this is help-full for you.

This is a convergence problem that can be as simple as poor solder connections on the pins of the convergence ICs or defective ICs. If you wish to attemp the repair yourself, please let me know and I'll look up the parts and provide additional details and instructions.

I used" Silerado 1st" solution. I have an Akai pt5598hdix/sms.
I had ghosting.Like 3 colors side by side.
Silerado said with TV off press "mute,1,8,2" then TV on.
I didn't see anything like a menu.He warned to write down any setting you saw before you change anything.But for me nothing came up. So as he said the next step try with TV "on" press "Mute,1,8,3" this is another set of adjustments for finer detail. I lined/overlapped all the lines up or down or side to side useing the channel and the volume buttons and then held the enter button down until the TV flashed 3 times.Then I shut it off and when I turned it back on It was perfect.

I just got this tv free and it will stay on for 15-30 minutes and then turn off. Some times it will stay on all day, though, so its kind of weird. I have the 5499HD
