Question about Hitachi 53UWX10B 53" Rear Projection Television

1 Answer

DP23 LED not lit on deflection board no picture on tv

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

Good Day, Gil;
Your problem is in deflection circuit (115+v) check these: FP05, DP15, Q777, QH01, TH01, T701, etc. BUT suspect C707 1k pfd, 2kv, and check all the pico fuses (brown) 2" to the right of cap. Good Luck, big IRISH.

Blue droopy line in middle of tv, everything yellowish above


Your convergence ICs Stk-392-110s Replace Both ICs.If 110s use 180s if 020s use 040s other wise Go by number on ICs .Mat electronics has parts 1-800-628-1118.Thats Cheap for 300.00 if you only have to replace ICs! Check all resistors around ics replace them if burt/read bad.RK42 3.3ohms RK46 1.8 RK50 2.7
RK54 1.5 RK58 3.9 RK62 2.2 ohms.

Blue won't line up at the top in digital array


you need to replace both convergence ICs and the six 1 watt feed resistors. The ICs are both STK392-110 and the resistors you need one of each RK42 3.3 ohm 1watt, RK46 1.8 ohm 1watt, RK50 2.7 ohm 1watt, RK54 1.5 ohm 1watt, RK58 3.9 ohm 1watt and RK62 2.2 ohm 1 watt.

Blue convergence


Thats the classisc sign that you need to replace both convergence ICs. You will need two Convergence ICs STK392-120 and then six resistors they are RK42 3.3 ohm 1watt, RK46 1.5 ohm 1watt, RK50 2.7 ohm 1watt, RK54 1.5 ohm 1watt, RK58 3.9 ohm 1watt, RK62 1.8 ohm 1watt. You can get replacement ICs and resistors at the following link and they provide free instalation instructions with pictures so you can repair the set yourself. Heres the link.
