JVC PD-42WV74 tv turned itself off and unable to turn it back on. Green light blinks on receiver and TV.
I had the TV on yesterday for about the length of three different dvds. In the middle of the last one, the TV turned itself off and both green lights on the receiver on the TV were blinking. I was unable to turn it back on last night and couldn't do it this morning either. I just see the green lights blinking. Could it have anything to do with overheating? Does it usually take that long for it to return to "normal" and turn back on? I have never encountered that problem before. I had to assume that it had overheated but I was stumped after it did the same this morning.
Re: JVC PD-42WV74 tv turned itself off and unable to turn...
For no known reason, we experienced the same issue. Our TV turns off on its own and the light starts blinking. I did unplug it for 5 seconds, but that really didn't resolve the issue. Perhaps unplugging it for a longer duration of time? Will try. Other then that, has any one else been successful at fixing this issue?

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. http://electronicshelponline.blogspot.com/
Yeah, I was going to suggest power supply issue. Plasmas IMHO, are not worth spending the money to fix. Its the reason why they are so cheap these days in comparison to LCD's. I had a 50" Samsung Plasma that went out on me within 2 years (E Buffer board and XMain problem). Its not about the manufacturer but more about the Plasma technology. Do a few searches about plasma and you will find a lot of problems with these tv's. Id say cut your losses, sell the TV for parts and buy a more reliable technology
Did you replaced lamp in TV recently? I think TV needs new lamp as existing is either broken or dead. Lamp replacement procedure would be mentioned in user manual or let me know to provide you more info. Thanks.
The most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board. I can't say it's 100% the problem because I can't actually look at the tv over the internet. If by chance the TV is still under warranty, go that route. If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.
I believe that this monitor will not work unless you have the cable from the media center to the monitor hooked up, I have all the parts from one of these due to the screen being defective on one of my customer's TV like yours. I have the connection cable that I could sell for $ 20. + Priority shipping of $5.65
It is protecting you and itself with high probability.
Power supplies in modern electronic devices are designed to cycle if there is a fault in circuitry they are servicing and because of the design, also will not turn on completely if they are failing.
The older style of power supply was 'dumb' and unable to do this so could cause fires if the failure wasn't teh 'right' kind to blow the main fuse.
I agree with the manual; this is a job for a tech.
guess what? I have the EXACT same tuner that u're looking for... my place was broken into and they TOOK the tv monitor... but left behind the tuner . smart thief. if u're interested in buying this tuner to make ur tv complete again. (its in MINT condition) email me at FAIR1968LANE@aol.com and put in JVC PD 42wv74 plasma tv in subject so i d know who it was. thanks.
