Question about Akai PTH5498 54" Rear Projection HDTV-Ready Television

AKAI PT5598HDI No picture

I have no picture on my TV. I turned it on and the picture was out of focus and then the screen went blank. I purchased the TV in July of 2004 and it was made in May of that year.
Do you think it is worth trying to repair?

    I have a Picture but the picture is not looking right. The convergance may be the issue. I have all the colors but the screen is bending to the center. I smelt an electrical burn smell and then the picture was out of whack.

    Thoughts?

    when I pushed the "on" button the tv appears to be coming on, and then suddenly it "clicked off". I have unplugged it for awhile to no avail. What's the problem?.

    Our Akai PT5598HDI also has no picture. Periodically we would get red color over regular picture, and then last night the red color came up, there was a flash, and now the whole picture is gone. Sound is fine, but no picture.

Dave,
Without a doubt it's worth the repair. The convergence amps have most likely failed and taken with them the +/- 30v line. Your unit takes two STK392-040 Sanyo built Ics at board location Icz103 and Icz104 and usually one or more pico fuses and some low ohm resistors. F1018 sometimes opens due to stress but generally it's just the two 6.3 amp pico fuses and if they have opened I strongly recommend replacing them with a 6.3 amp slo-blo pico.
The low ohm resistors at RZ147, RZ146 usually show signs of heat stress and may even be burned beyond recognition. Testing at that point is almost unnecessary but will confirm their change in value. Almost always they need to be replaced.
A quality shop will have this unit back on its feet in no time - faster if they have the parts in-stock, which you might ask about when you shop around for a good repair facility.
Have a great day!
Bill

If the ghosting is like a 3D effect its your convergence ICs , but if its like a blue Halo around objects that usually means your CRT coolant has congealed and will need replacement. The blue is the first tube to congeal for some reason, followed by green. Red seems to be not quite as prone to this. It is a normal occurrence n sets about 4 years old to need the coolant changed.

http://www.fixya.com/support/t1663670-akai_samsung_pt4299hd_convergence Adjust the convergence manually. It's a pain and takes alot of patience. The diagram for the remote buttons helps a lot. If it won't adjust you'll have to replace a part inside the tv. Good luck! Hopefully it'll adjust.

My 42 inch Akai is about 6 months old,, and is showing green where black should be..
BUt there is help for you all.. Call Verizon, sign up for their "Expert Care" program. it's $10.00 a month, and active after the third month.
with a $75.00 deductable. THey will fix or Replace (give you choice of three alternate models/brands).
Free services under this plan are adjustments, and One FREE remote per year!.
i recomend you sign up for this program, and after 90 days. call for service. They more than likely will replace your TV's.
This is what they did with mine..
ALSO.
it doesn't matter how old your TV is, the plan is applicable to all TV's in your household. So one plan, one monthly payment of $10.00, covers all the TV's you own!!
