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.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.

If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light flashing codes, circuit diagrams, test points, and part# lists. Usually, cost under $20. And most cases the new part cost less than $15.

I hope I shed some light on the subject for you.

I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one
circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.

SOURCE: i have a 42" plasma

that is most likely and most commonly a faulty power board or power inverter. It will hold just enough power to light the lights but nothing else. Sometimes the tv may even turn on until you press a button and it turns off.

Can jvc vm-42wx84 be used as a monitor without tuner


This is a screen with a media box. The box has two connections to the display panel. The first looks like a DVI connector. The second is the proprietory control port connection. This is how the set receives commands about brightness, contrast etc, scaling, aspect ratio. It might even control such basics as power on/off.

You could try the panel just with a DVI connection, but you will have to make sure that all sources are scaled to the panel's native resolution (1024x768) before they reach the screen. This is part of what the media box does. You might be okay if you're driving the panel direct from a PC graphics card. But if you want to run it with a variety of different sources then you really need to use the JVC media box.

I can't say if the Hitachi media box would work.

Jvc AV42PD20ES 42INCH TV


Hello gladwin6,

You may have at least a blown fuse. However you may also have other damage to your power supply. This often happens due to the voltage spike caused by the power coming back on suddenly. You can check to see if the fuse is blown, however once you change the fuse and if this does not take care of the problem, I would suggest that if you do not have a background in electronics, that you have a qualified technician take a look at your TV set.

I hope this helps,
Thank you,
