53H71 Toshiba Here is the problem , I have a Toshiba 53H71 there was a blinking red light and it would not turn on i replaced the IC's the TV set turned on and was working fine. After about an hour same problem , i noticed the 851 was blown replaced it , than 850 blew. I replaced both of them now the tv set will go but there will be no picture. There is no more red blinking light problem the menu does not come back nothing , the lamps do not go on? what could be the problem thanks.

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.

Here is a link with instructions on how to do this, if you feel adventurous:

Should you find this info useful, kindly take a moment to "Accept" it. Thanks.

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

Either the convergence or cracked sautering. Just had my tv repaired but now I have a double blur in the upper left corner.

omg.. i have the exact same prob...
is it a conindenice that we are all having the SAME prob around the same time?

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.

Convergence amp ic bad
