Toshiba 50H81 Has Power but No picture or Audio

Toshiba 50H81 had the dreaded flashing power light so after checking TV forums on the net I found that the convergance ICs could be bad so I replaced them. Also found 3 blown fuses on power board.Replaced them also. Now power light stays on but no picture or sound. Any help would be greatly appreciated. Thanks

Ok i'm goin to need more info about your problem. you stated fuses and didn't say the location numbers of the fuses. Also, have you rechecked your fuses to see if they are all still good? 3 fuses sounds like more then one problem. once you tell us your loc#'s of your fuses, we can look into your problems.

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.

Red power light flashing; will not turn on.


It is very likely that one of the convergence correction chips has gone south on you (either that or a capacitor). What you want to look for is a swollen capacitor , or a burnt resistor near the two large heatsinks on the signal/convergence PCB. The flashing LED is an indication that the power supply has detected a fault, your mission is to determine what that might be. another thing to check out at the fuses on the power supply PCB (these have labels like FXXX were XXX is a number). If you find an open fuse, that will help determine where to look for the fault.

Have a toshiba model # tp55h95 tv. The power light is blinking


Something is keeping your power supply from starting up. Bad capacitor...most likely. Replac 'em all! They're cheap!

Toshiba TP50H95 No sound no picture


Sounds like a problem in the deflection circuits either vertical or horizontal. You may also want to check the solder connections in the tuner as they have been known to develop cracks over time. But the prior shrinking tends to say deflection problems.If I can assist you further please let me know.

No picture no sound and power light blinks.


Did you check the supply fuses to the convergence ICs? Did you check the output resistors
other wise i would replace the convergence ic first.
