Television and Home Theater

I recently had my Mitsubishi ws-55511 repaired. It needed a convergence chip replacement as well as the 7 "capacitors" that usually go bad with it. When the "guts" were re-installed and everything was re-connected I no longer was able to get full HD signal from my cable box into the dtv-input on the rear panel. Before the TV(guts) left my house I was enjoying a very fine HD picture until I was having the red & blue blurring issue due to the convergence problem.  I can hook up the Blu-Ray dvd player to this input but, it only delivers a 480p picture.

I have replaced the 2 ICs and the blown pico fuses and now the TV will stay on. I  even have audio. The problem is there is no picture. The self test reveals no error codes. Sounds great, nothing like a 55" radio !:)

Any ideas?

I have a Mitsubishi WD-62527.  We had a power outage and since then all my tv will do is blink a green light for about 30 seconds then shut off for about another 30 seconds then try again.  It seems as though its trying to boot up but something is causing it to fail.  I just put a new bulb in the TV 2 days ago. Please tell me what part I might need to buy or any advice that i might need to check.  I have already checked power and fuses.  When the green timer light is blinking the fan motor is running next to the bulb???

 Thanks
