No picture and the power light blinks


A red blinking light could mean that the lamp timer is at it's limit and it is time to change the lamp. You will also have to reset the lamp timer by pushing and holding down 2-3 buttons on the tv or remote. Refer to your user guide for the proper way to reset and or change your lamp.

Tv won't come on


Mine is Toshiba 55 TZ, have it since 98', shutdown and red light blinking problem, search the ned 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 mo $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.

Lite in the front of the TV when you turn on keeps blinking and no picture.


Q510, Ta1316 is your sync processor and probably the problem you're having here. It's a common one for this unit and you could pull the board and check the solder connections it has with the foil - - but you may need to replace it...
