Question about Televison & Video
JVC LT-26C31BJE lcd tv standby light blinking nothing else happening except for a clicking relay smps board number LCA90256
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?

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 firstname.lastname@example.org

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.

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.

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.
