Hitach dead set

[JJS]

Have Hitachi 53fdx01b bought at garage sale 4 years ago and has been working great, until now. After thunderstorm took out cable to house, my set will not come on but red led lights up on front of tv to say its on. Pulled back cover and all leds light up on power board and on convergence board, but led dp29 will fade out to nothing after about 15 seconds and led dp37 stays lit but pulsates slowly. Have replaced the two main convergance ics, pico fuses check good as well as resistors to replaced ics. I know its an old set but if I can fix cheap, its still better than buying new.
