Question about RCA P46924 46" Rear Projection Television
Rca p46813bl convergence problem bowed in the middle,at top and bottom
OK., I know this set very well. It almost never has a convergence problem.
With the set unplugged, remove the back cover--there is a small circuit board mounted ABOVE the main boards--it is about 10 inches wide and 4 inches tall---On the far right side of it are several DIODES---two are much larger then the rest--what usually happens is one of the large diodes is shorted--5 dollar part---the board only has a few plugs and 4 screws that hold it in---easy to remove--check all the diodes(the two large ones first)
If either of the large diodes read like a fuse you FOUND YOUR TROUBLE.
LET me know if you need ANY help or Advice--I am here to help people---I have seen several sets identical to yours with the problem you describe.
Regards, SD TECH
