Bad components in the horizontial/vertical output. High voltage (flyback), even a bad relay or weak component. These 'steady' failures are often thermal problems as some components fail, they work when cold, turn them on, they heat up, they fail, they cool off, they work. You can pinpoint with some cold spray. When it fails hit the chip or component you suspect with the spray, if it comes right back. Thats your circuit.

Have a black screen infront of my tv picture but not when I use the vcr I have a toshobia cn35f90


Turn off closed-captioning on the TV. It's gotten turned on and set to "text" mode. There's a button on the remote to control captions and it's easy to do without realizing it. Use the button to go through caption settings to turn it off and the box should be gone.

The red light is blinking and the tv sounds like it on when unplugged and replugged; but there is a black screen.


Hello,

If you are having sounds but no picture, it is either the lamp or the t-com board.

But if it does bot display anything or make any sound at all but from inside the unit it sounds like there is power in the unit, then it means there is a problem with the main panel of the television. Most likely a bad capacitor.

Have the unit checked for bad capacitors and replace them and the television will be in good condition once again.

Take care and good luck

While watching my toshiba cinema series 36'' television yesterday the screen faded out and made a popping noise for a couple seconds. The picture came back but I have no sound now. Any idea what system...


I'm going to speculate. Audio system component shorted (output), changed bias and picture faded, *POP* component failed completely, bias returned to normal, picture returned.

?Shorted resistors and/or chips in audio output circuits?

I wouldnt expect electrolytic caps to be a problem in these newer units, but you might check for open caps too.

Check your level from the power block, if you can scope your B+, check the ripple. If its bad, the PS block may have been damaged.

Take this with a grain of salt. I'm not real framiliar with these units.

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.
