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