No picture or sound after a few minutes, replaced blown C812 but problem returned

Hello, the unit has no picture and sound after a few minutes. When this first occurred we replaced C812 which had blown (a 100v10uf electrolytic) and everything worked fine for about three weeks. The no picture and sound after a few minutes condition has returned. Capacitor hasn't blown again yet BTW.

Hello to all, I have a tv zenith model C27V36, and it has a problem I connect it in the series and it does not turn on and I connect it to the network(net) and immediately burns (damages) the horizontal exit that is a trasistor C5905 and it burns (damages) both resistances of the protection,I changed the trasistor C5905 for a trasistor C3997 that is 20 amps and nonetheless it burns it,there are no signs of short circuits. Could the problem be the high horizontal ocsilacion?? But since turning it on it burns(damages) the horizontal exit I do not have way of checking it, because it is automatically damaged . can someone please tell me what to do in this case??? Or where I can find an electronic diagram or a sketch??? Or can someone who has worked on this TV before h
help me out?? It is a zenith model C27V36 of 27 "..
thank you for you help.

TURN T V ON AFTER ABOUT TWO MINUTES IT GOES BLACK


This is a problem with the power supply unit and sounds like a hardware failure. Many times the capacitors go bad but it could be a Transistor that is weak and not working once the unit get's "warm" I recommend having a technician trouble shoot and repair the unit. In some cases you can find parts or a unit that is identical with a different problem on used electronics sites such as ebay. The unit will need the bad part identified by a tech and replaced. I am unaware of any menu items or service modes that will repair the issue. Hope that helps.

WD-73733 Sound no picture, replaced lamp, still not working


I assume you were getting a code flashing on the front indicator showing a lamp problem? 34 code is common and indicates "lamp abnormality" If you are not clear on how to read the code I believe your owners manual has a section explaining that. If the lamp was blown it is possible the ballast board that provides voltage to fire the lamp is also defective and this may also give you the same error code. I would recommend also that you first reseat the lamp assembly to be sure it is fully plugged in. Also be sure the lamp door is postioned and secured properly (this typically will give a different error code, however) Also try unplugging the unit for a few minutes to reset and try powering it up again. Sometimes this will clear a problem.

Picture is gone! :*(


the picture tube (what makes the TV picture work) has blown out. Just call you nearest tv reapair shop and purchase a new one. (these are kind of expensive!)

(Also, if it's fifteen years old, i think it's time to get a new T.V. hint. hint.)

SOUND NO PICTURE


Hello, You have a high voltage section problem I would not suggest fixing this set on your own. You will need to take this set to the shop. Because there are no user repairable parts inside of the set.
