Question about RCA HD52W59 HDTV Projection Television
My tv comes on, the power light comes on, but it won't stay on, it goes off by itself a few seconds later. Is there a solution to this? RCA 52"
I re-did the joints around the flyback transformer and replaced the convergence fuse. This has fixed my TV "for now".
Convergence fuse fix: Since I had to order the part I made a jumper wire to replace the fuse until I recieved the new "fuses" Purchased 4 for future issues :)
Convergence issue is when the three guns red, blue and green are not lined up and you're picture looks like a 3d movie. The fix is simple and can be done in less then 15 minutes. Provided you have the right screw driver and some general knowledge of soldering.
Problem: TV turning on for 3 seconds no picture then shutting off.
Fix:Re-fluxed and soldered all contact points at base of flyback transformer.
It may be better if somone just took the entire board out and re soldered every connection and joint on the board. I took pictures of the board and the fix.

My RCA 52" projection won't come on. Before it shut down altogether, if would go on and off repeatedly.
My TV man wants about $500 to fix it. John Burton

The first thing I would do is to check the solder connections on the flyback transformer. This is a common problem with this set

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to.
I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.
The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)
You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.
What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).
You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.
Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.
I hope this helps.
