Problem started with blue convergence not lining up. replaced red and blue ics and RK50 and RK54 resistors for hitachi 53uwx10ba. connected and powered up tv - 5 minutes into warm up picture started to go. picture went out. tv will power up - red power light is on and all LED's are on except LED DP23 on deflection board. TV powers up but no picture or sound. Have full schematics for tv but unsure where to go from here. NOT a tv technician and trying to fix on my own. Not sure what to do now. Any help would be much appreciated.
Thanks,
Gil
