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

A lot here would depend on the model number as there are a lot of different ones with different issues.

Got a model number?

did you hear the sounds? or maybe you have defective power source in hot side..

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.

Hi,
Let me know is it Toshiba 32A43 tv or any other model?
Do you get sound of tv in any input, like dvd playback or cable channels?
Can you test voltage in circuit board with multimeter, it will help me to diagnose problem.
I'll try best to help you to get this tv fixed.
Thanks.

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

I have the same problem, did you have any luck?

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!

Here's the online manual for your TV:

Read the section about the red/green lights in front. It sounds like the lamp went out. Mine consistently goes out once every year to year and a half. If you plan on keeping the television, purchase two bulbs, so you have one on hand in case your new one goes out.

Good luck.

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.

If you have the owners manual look on page 64 and see what it says there about the light lighting up in the front of the unit. if you do not have the owners manual, you can get one for free here: http://tacpservice.toshiba.com/ConsumerProductSupport/Manuals/TV/2004/52-62HMX84_E_R1_093004.pdf
