I brought a R52WH74 2yrs ago, I have already replaced one fuse FL231. Now the TV tries to come on( still just the green light on, no picture) but now I have the thin color bars horizontally in the center of the screen, now what?. TV tries to reset three times and then goes off.

On same Board that you replaced fuse Look at cp 150 if it is puffed up on top it is bad so replace cp150,114,120 one will be 2200u 16v
other 2 caps will be 220uf 35v With tv turned OFF Press and Hold Vol- and CH - at same Time on Front Panel board wait untill set comes on you should now be in Service mode Go to Convergence Try to aline convergence Do Auto converge
ok, the problem with short detect.... unsolder all convergance ic's and try to turn it on. does it come on? if no, check all diods in the power suppy area. check h-output unsolder all convergance ic's and try to turn it on.
does it come on? also might have a vertical ic. mmm, check all fuses including the solder in pico fuses. beleave they are sold green color. when i get one that comes in they have 1 or 2 blowed pico fuses and that means convergance ics need replaced along with fuses. good luck!!
Instead of taking the board out, I just soldered two wires to the old fl231 fuse on the underside. Installed a fuse holder with a half amp fuse. And I re-soldered all of the flyback points. My tv is working like new. thanks for everyone's help.
