Look carefully at metal jumpers feeding b+ to convergence IC's.

Both will need re-soldering or you will keep having problems. 

Let me know how it goes.T.

    In the service literature,follow the B+ supply back from the IC's



    I.e. follow the traces--will take you to the metal wire jumpers.

My Toshhiba 53H71 went black and the red power light keeps blinking. Is it worth repairing.


Hello,


You can repair it, it is repairable, the problem is power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Hope this will helpout in solving the problem....

Yes, the convergence IC's need to be replaced. If you are not experienced in TV repair, I would recommend getting a qualified repair man to do it for you.

Toshiba projection tv with lines on screen


I have seen a lot of sets where the problem only happens when the set is first turned on---99% of the time one of the two STK-392-110 CONVERGENCE chips this set uses is Flakey--intermittant---The only way to know is replace both of the convergence IC's and see what you have---a bad IC can cause the set to shut down---and sooner or later the set will just shut down and not come on at all.

Let me know if you need more information about this type of repair as I have done hundreds of sets with this type of problem----every one I have ever seen where the convergence was intermittent----replacing the two IC's cured the problem.

REGARDS, SD TECH

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.
