Check to see if horizontal output is shorted, But will have a damper diode, between the base and emmitter, will read 0 ohms. That's okay to check like that, Check for shorts between collector and emitter and collector and base. If ok, check for 130v dc on the collector of the horizontal output transistor.

Power surge


Yes possibile there's some IC's that are burn inside it and also the power supply can be damage so resetting it will not do anything , if you can take it to a repair center and let them check this unit and fix it.

Good luck........

Toshiba TV won't turn on


Toshiba? Suspect that if it uses a Lamp for brightness (a model number would help) it may have failed----customer replaceable and if remove look to see it is not shattered inside--2 year, 2000 hour life is normal.

RED LED FLASHING WANT STOP/TV WANT COME ON


Check power supply to see if its working, check across main cap, Do not use chassis ground for 160v. If good, check for 130v on the collector of the horizontal output transistor, if missing voltage, check for either an open low value resistor in the power supply or an open pekoe fuse or a bad voltage reg ic.

When we try to turn on the tv (toshiba model 32A43) it makes the sound of turning on then off and the screen stays black and a red light by the power button keeps binking


You're either losing high voltage or power supply is not producing the horizontal drive signal, Check for 130v on the collector of the horizontal output transistor, if you're missing your voltage, you have a power supply problem. If voltage is too high you have something open in the power supply such as a low value resistor. If its low, something is shorted in power supply, possibly voltage regulator ic.

I have a toshiba 32A43 and my screen is flashing green. Any ideas on what it could be?


green normally means exspensive to fix. the bulbs are the most exspensive part to fix like draging a magnet across the tv, get what you can out of the tv a start looking for a good deal but avoid phillips and magnavox please.

Toshiba 32a43 32' picture garbled mess


If you can get the tv to display the blue blackground(usually happens when there is no antenna or cable feed to tv) check to see if the whole screen is a solid blue, if it shows discolored areas around the screen then you might have to "demag" the screen. See if you can rent a demad coil from a tv shop and with tv on turn the coil in circular movements all over the front of screen till blue is solid.good luck!

Toshiba 32A43 Horizontal Bars, pop, no picture.


First of all, there is no such thing as a "high power flyback converter". There is a flyback transformer, but if it was bad you would have absolutely no picture at all. The fact that you dont even know what the basic components are suggests that you should not be "diving in" to someone else's TV. Do everyone a favor and allow an experienced tech to service the set.
