52" RCA d52w19

Hey there. My 52" RCA rear projection TV seems to be a bit tempermental lately. Approx a month ago it started turning off by itself when it was initially turned on. We waited 20 seconds or so, turned it back on again and it would turn on and be fine. Now when the TV is turned on the green power light turns on for approx 3-4 seconds, turns off, turns back on for a few more seconds then off for good. When we follow the pattern of waiting 20 seconds or so to try to turn on it won't go. It's like it wants to turn over but just can't grasp the right power. We've changed the flyback transformer but that didn't seem to help. Any idea's TV Coa? We're pretty handy at fixing things and have patience to boot we'll try just about anything since we paid over a grand for this tv and it's just 3 yrs old.
Thanks a bunch!!

    Is that capacitor on a sliding tray or a fixed board? Where exactly is the board when you are looking at the back of the TV?

REEPLCE ANTENNA INPUT ON D52W19 RCA PROJECTION TV


Often they can be soldered back onto the tuner. But the tuner itself may need replacement which you can get tuners and the entire SSB which has the tuners already on them from www.tvrepairworld.com

Screen TV shuts down


Sounds like an electronic part (a resistor, a diode, etc) that stops conducting electricity when it heats up to a certain point. Maybe it physically loses contact on its circuit board due to a bad solder, or the part itself is internally defective. Unfortuantely you'll need an expensive professional repairman to diagnose it. TVs have high voltages, ya know, and can kill you if you go mucking around inside.
