Check out Ceramic Capacitor C514 by the horiz. output transistor (burned/shorted?) My question is how do you find the specs of the capacitor and where do you buy one?

SOURCE: AKAI 32" LCD HDTV WILL NOT TURN ON

The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to jah2mil@hotmail.com

You most definately have bad capacitors in the power supply. try and get it repaired as soon as possible, not an expensive repair that iv'e seen.

SOURCE: JVC LT-32P679 Blinking Power Light, Automatic Shutoff

1. Hold [menu] and [vol-] button on the side of the TV
2. while holding these, press the [power] button on the side of TV (NOT remote)
3. blue light comes ON and stays ON
4. wait 10 seconds then let go of [menu] and [vol-]
5. wait another 30 seconds and some type of picture should appear

I think this is right. I got it from the JVC call centers guys so sorry if I missed or messed up a step.

I replace the lamp and now the tv powers on and after a few min turns it self off and power button blinks red


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

9 year old Sony Trinitron TV 27 inch; a red light is flashing "standby, timer"; have tried to cancel this but the TV won't turn on, just hear a clicking sound when pushing the power button


The key here is the number of blinks. The standby light should blink a count followed by a few second pause with the count repeating. That count coupled with the model number will giveme enough information to provide you with a solution. Can you uipdate this with that info please?

Thanks,
Dan

I have sony lcd hd ready 50inch rear projector tv model number KDF-E50A12U tv comes on after couple minuets tv clicks off to stand by then red light in stand by flashs 3 times gos back to green repets


Hello
Three blinks of standby light to Sony TVs indicates that the regulated voltage output from power regulator board is above thatn normal. The problem is with its power supply regulator board. Replace all the electrolytic cpacitors on that board with new ones. Replace all of them including small and large ones, at one time. OK.

Blinking powerlight on front when i try to turn on tv


This is more likely a power supply failure. Most causes of tv failure are due to bad capacitors on either a system board or the power supply. In this case, it sounds like the power supply. You can test the capacitors with a capacitor tester to determine faulty capacitor. You can also test other components like power supply current with voltmeter or mulit-tester.

Standby light keeps blinking. tv wont turn on


If the TV goes off completely, then is usually a faulty power board.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

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

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

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 , starting the flashing light.

If you are in situation one, then the TV 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.

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.

Jvc av-56wp74 power up failure


Hello hwkdoc,

 

What has happened is that your shutdown circuit relay has tripped and it looks like it also may have malfunctioned. This however is not the cause of your problem but a symptom. The cause of your problem is an over-current condition caused by one of the systems in your TV, I would suspect the high voltage power supply or the switching low voltage power supply. These are the first places to look, if they are not the problem then check the convergence correction amplifiers. Right now the shutdown circuit is keeping the TV from coming on. If you do not have a background in electronics I would advise you to have a qualified TV technician analyze and repair your TV.

 

Thank you,
