Question about Televison & Video

1 Answer

I have a rear projection TV 50" TN50X81. The unit will frequently turn off for no apparent reason, and unable to turn back on for awhile. It seems that maybe when it reaches a certain temperature, it turns off, then must cool down again(?). Thank you.

Hello,

All you have to do is to open the back cover of the television to check for dry soldering, bulged capacitor, You need to check the output voltages of the power supply to see which one goes off. It may be due to short circuits some resolder where necessary, but if otherwise the power board is bad. you can check on ebay.com, shopjimmy.com for a new power board for the television.

Hope this help in solving the problem.

Toshiba TN50X81 50 TV


More likely is the set is in shutdown---most common issue on this type of set is the convergence---to know you would have to locate and unsolder both 18 pin convergence chips---with them out of the circuit if the set comes on (will not look good) one of the two chips is shorted--these sets have very good protection circuits to prevent many parts from being destroyed at one time..

These are the chips--STK number is right on the front.

Television will not turn on - power light blinking


i have seen before that model have pretty severe cracked solder connections on the power board. otherwise those types of tvs can have convergence failures that will keep the tv from turning on.

No picture after replacing convergence ICs on TN50x81


You likely have shorted soldering. If you bought a kit from someone go back to their site and ask for help.

Convergence Issue on Toshiba TN50X81 - Service Manual & Parts Source?


Replace the convergence IC's - P/N STK192-110 with part STK192-150 or 180. Then you can go back in and make the detailed convergence settings and get your picture back in alignement. Also check the flame-resistant resistors around the ICs to make sure that none of them have opened up.
