SOURCE: Burnt Zener diode... Voltage spec??

On the cathode of the zener diode look for a filter cap and check its value the voltage of the zener should be less than the working voltage of the zener. Basicly its likely being used as a shunt regulator as protection and regulation of the voltage. When the zener hits a certain threshold it will breakdown and start conducting to ground until the supply regulates and then it will recover. If the filter cap for that voltage rail was 25V I would guess that the zener would probably be regulating between 12 and 20 volts. I'd pick a 15V Zener its probably +- %10 on the original and any system should be able to take a %10 tolerance as a general design rule.

Hi.

If you have no picture, no sound and the TV stays in standby it is not the remote sensor. That is the TV in protect mode (forced standby). The TV goes in forced standby when an internal problem is detected. Most Sony have buttons on the TV set. If problem is the IR sensor the TV Twill wake up if you press the channel buttons on the set. Try disconnecting power cord for ten minutes. If that does not work call the Sony support number listed in your user guide.

Regards.

I know its a 32 inch TVand its probably about 2 years old, give or take. If you got a warranty on it, I suggest calling whoever you got it from (BestBuy,Amazon, etc) and seeing what they can do for you to get it fixed for free. Otherwise call Sony abotu getting a real tech out to either fix or swap parts on the TV at your house, or where to send it for repair. Depending on what it costs, you are probably better off buying a new 32inch LCD TV for about $400.

It seems you have isolated it down to the power supply though. If you are confident enough, you can get a replacement on ebay for abotu $100.

Just depends on what you value more: time or money.

Whenever i plug my sony bravia KLV-32U300A, it click twice and doesn't turn on,power sign goes completely off. I have to unplug from the power source, wait 5 mins and try again, it rarely turns on, but...


Hi,

This is an indication of out-of-regulation in the power supply section. The very common caused of this fault is the leaky electrolytic capacitor in that section. It will drop the supply from normal voltage and will disable the unit.It needs a little warm-up to make itself stable but the symptom will get worst, times will come that it will not power up at all. Sometimes it has a bulged/dome at the top but not all, it is better that you have a capacitor checker/tester to determine its condition. Your unit will back to normal again if the leaky capacitor is isolated.

If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored electricity enough to hurt you with a little mistake only.

Also check if your unit is under warranty /extended warranty, avail it because the manufacturer of your unit will fix it for free. Don't open the back panel, this will void the warranty.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.
