I have a JVC model number 47 x 579. It is about 2 years old I haven't wached it in a couple days. I turned it on and it didn't turn on. The power light starts flashing after about 12 or 13 seconds. It will not access any features. In order for it to turn off I have to unplug it. When i plug it back in and try to turn it on again the same thing happens. I really enjoy this tv and I'm confused as to what the problem is. Could you please help me out? I don't know if you need my email or not to get an answer so here it XX.XXX@XXXXXX.XXX
I have tried repetedly hitting the power button, accessing other functions such as games, only way to get the blue power light to stop flashing is to unplug it. I plug it back in. I try to turn it back on and after about 12 seconds it starts flashing again.
How long have you had the set for, and when did the problem occur?
Was it after a storm or power outage?
Does the standby/timer light blink continuously, or in a pattern (such as 5 blinks, pause, 5 blinks, pause, etc.)?
We have had the set for 2 years and 7 months. the problem started three days ago.
there was a storm two days ago but there was no power outage and the set wasn't being watched and is hooked up to a surge protector. we've had power outages in the past and it has never effected it.
The standby/timer light blinks continuously.
Okay, just to be clear...a good surge protector will not prevent damage to the TV's power supply capacitors during a storm. It simply cannot react quick enough to voltage transient peaks (which can occur at the speed of light) Also, it can take several storms, surges, etc. to slowly start to damage the capacitors......so each one could have started to short the capacitors little by little. That being said, please disconnect the set from AC power, then press and hold the power button on the TV itself (not the remote), for 10 seconds. After another minute, plug the set back in and press power once. Do you still have the same problem?
Yes it is doing the same thing.
Are there any buzz, hum, or clicking sounds coming from the set, or is the only sign of life the continuously blinking light?
The standbye/power light will stay solid for about 12 or thirteen seconds then a click and then it will start blinking. other than that no sound while the light is blinking.
The click is the power supply disengaging due to a short on that board, then the blinking light indicates an SOS (failure).
It is most probable that there is a failure on the power supply board inside the TV. Commonly the capacitors on this board will receive a surge and then fail. They can sometimes be visually verified by removing the rear of the set and inspecting them for bulges or leaking fluid at the top or the base of the caps. This is the most common mode of failure for these sets.
The capacitors are located on the power board inside the set, where the AC cord plugs into and can be replaced by a Tech for no more than $200 parts and labor.
Unfortunately there is no sequence of buttons or reset you can perform to get the set working again. Do you have any experience testing live voltages, or soldering on electronic equipment?
If not, then I would suggest using the link below to locate a technician in your area:
