Question about RCA HD50LPW175 50" HDTV
there are many possibilities
a) turns on and off - might be on the power supply board
might be bulge or dried capacitors on the secondary side of the chopper transformer
b) color appears to be double -- convergence problems
might be open fusible fuse, or capacitor
c) more gray -- digital circuits
Initially can be check by a visual inspection of the boards, then the voltage checking on some points.
important is the B+ it determines the status of your TV, once it is noted some points can be isolated and checked.
include the make and model of your TV .
