Question about JVC HD-56FB97 HDTV

2 Answers

I have a JVC HD-ILA HD-61Z575. The color engine was replaced under warranty a few years ago. Recently, I started noticing some color artifacts in the picture... basically in a dark picture, you can notice red, green, or yellow stars randomly on the screen. If I turn the TV off and back on, they usually go away and don't come back until the set has been off for a while. I tried cleaning out the bulb area and that didn't affect the issue. I've also yet to have to replace the bulb in the tv, and it's been about 5 or 6 years since I bought the set.

    Looking at the pictures online of the burned pixel issue, I don't think that is it. These aren't little stars like what you see at night... These are large, generally 2-4 inches in diameter, and looks like a lens flare effect in photoshop, just in different, random colors... and not always in the same part of the screen.

Sometimes with just one, sometimes 5 or more.

I only have bad news for you. This tv uses an engine assembly. It is impossible to replace the color wheel only. The entire assembly is quite expensive and wouldn't be worth replacing for a tv of that age. (By expensive, I mean roughly $400-$600, before labor). To replace the assembly the tv is basically broken completely down for this repair too and thus very expensive for labor as well.



Sorry for the bad news, but with no warranty you seem to be out of options. Some people choose to just live with the color issues, while saving for a new tv.



Thank you and have a nice day! :)

    I would agree you do not have burned pixels at all. Your condition is known as the "blue spots of death" as some people call it. Not always will the spots be blue, it can be any color on the color wheel within the main assembly of the tv. I still have to stand by my original solution due to the fact I have ran into this issue many, many times. That is the problem with tvs that transitioned from LARGE projections, to DLP, then to flatscreens. They had to find a way to make them smaller, hence the color wheel assembly. These reduced the size of the tv considerably, but this is a VERY common problem with DLPs, in general. I wish I had more good news for you, but your options are...new tv, OR new main assembly to correct your image problem.



    Thank you!

That is the so called burned pixel common issue on LCD projection TV. There is no repair in this kind of problem and is very expensive replacing the LCD screen inside the projection...just like buying a new TV set...

Gray spots on screen on a JVC HDILA model HD 56G 787


The HD-ila sets accumulate a lot of dust in the light engine. The worst offender is the little fold mirror just under the lens. I take my set apart about every 8 months or so to clean all the dust from the light tunnel and all lenses, mirrors, diffusers etc. The picture really regains it's pop when this is done. Unless you are a skilled technician though, I would recommend against attemptimg this procedure as you need to disconnect the individual color lcds. Check with a local service center to get it properly cleaned.

Green Tint on half of the screen


This is most likely a defect in the optical unit (about $1500.00 part). If out of warranty probably will just have to live with it. Those op units are also hard to get.
