JVC VM-42wv74 Problem

I am having an intermittent problem with my display. It periodically displays what I call a "gamma" problem that flashes up in the lower half of the screen. I have attached a photo of what it is doing. This is not a constant thing, nor can i find anything that I can do in order to make it happen. I am assuming that it is not something terribly wrong with the display portion since at other times it displays the image perfectly in the same areas? It only flickers the problem on and off at times there seems to be either vivid bright colors in the bottom area, or very dark regions that cover a large area of the screen.

I dont mind doing some parts replacement if you might can tell me what parts to replace and where to get them! It is currently hooked to me Mac as you can see in the photo, but problem persists when hooked to any input, composite, S-Vid or Digital. If you woudl rather, my email is madison.p@insightbb.com

Thanks in advance,
Philip

If the unit is under warranty, send it in for service. Send along the picture as it will help to show the problem. Explain as well that you can not force this to happen thus it is an intermittant problem. That will help if it can not be "fixed" at this time. The re-appearance after the warranty ends will still be covered as it was reported during the warranty period. This is usually a logic problem within the video processing. Unfortunately, without reproducing the problem and measuring inside the unit, there is little that can be done remotely to resolve this.

JVC PD35D30 Plasma won't turn on anymore...


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

Our 42" JVC plasma now has a black line right in the middle of the screen with some colored bard similar to performing a "defrag" on a PC. Is our set "shot?" it's only around 6-years old. Model # VM-42WV74...


I had the same problem with a JVC VM-42X795. The repair man said a wire in the monitor is probably borken that provides power for that enire row. I stared with one bad row, but ow I have two.

I have the same problem with my JVC PD-42WV74.


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 hope I shed some light on the subject for you.
