Question about Toshiba 50H81 50" Rear Projection Television
This afternoon, I discovered that my Toshiba 50H81 has a problem. When I power the tv on, the red power light simply blinks. I called Toshiba and the friendly person who answered the phone told me that I needed service. Their assistance was overwhelming. (sarcasm alert) I contacted two local repair shops. The first estimated, over the phone, that the repair will most likely cost $350-450. The second shop was not very helpful and warned they might not be able to get parts because the tv is y yeras old. I searched the Net and found similar problems. Several people reported IC convergence issues and blown fuses. I took the back of the set and quickly realized this is something I cant fix myself. I welcome any feedback or suggestions. Is it worth fixing such a 7 year old tv?
It is in stand by mode, chech your settings...all of them return them to mfg default then go from there

Mine is Toshiba 55 TZ, have it since 98', shutdown and red light blinking problem, search the net and found out, generally a Convergence IC (stk392-110) problem. bought 2 for $15 at suburban-elect.com (ebay). replaced following direction from http://www.casiasfamily.com/repairlog/tp50h15.html
Open back cover, 9 screws and wirings (pls mark), removed(soldered) a electronic board infront of convergence ic. removed IC (stk392-110) (screwed and soldered).
Replaced everything and voila...! it is now working again..
no more shutsdown and red blinking light. Saves me $400 for a repariman. of course just be careful with static and stuff.
I don't know how to solder, so I ask friend to do it for me. But I did the rest. Just to give you an idea that it can be done even if you don't know much about electronics. This in no way a recommendation but just stating my experience. Follow at own risk.
