Marantz RPTV repair


I have a Marantz PV6080W 60" CRT RPTV with issues. I think the blue lamp is going out, as all blue images on the screen have significant halo or border fuzziness. All other color images are crystal clear. Is that typical of a failing lamp, or one that needs to be redirected/refocused?

I've tried dealing with Marantz CS for hours on hold and through their poor online support. Finally, they just told me to talk to Phillips CS, as they don't support their own DLP products anymore.

If it helps, I could take a picture of the screen to demonstrate what is happening. If it is one of the above problems with the blue lamp, is it reasonable for a relatively tech savvy person to attempt the repair?

Re: Marantz DLP repair


A picture would be good. Did this just start? If it did, then I'd have to think about causes. My first reaction is "chromatic aberration" (aka "fringing"), which is a lens quality issue, often with blue.

BTW, for a DLP, there is only one lamp, so it would be the blue filter (segment of the color wheel) that might be dirty.

Re: Marantz RPTV fuzzy blues


This has been going on for some time and seems to be stable, but very annoying. For example,what is intended to be a sharp blue box image actually appears to be cloudy at the edges, like a street light in fog. The soonest I could post a picture would be tomorrow evening. Also, I might have the technology wrong -- it may be a CRT RPTV (see link to model info here). Thanks a lot for the help!

Re: Marantz DLP repair


I am not specifically familiar with that set, but I suspect that it was made by Philips and you are experiencing the contaminated coolant in the blue CRT that is very common with Philips CRT RPTVs. The green will do the same thing. The CRTs will have to be taken apart, cleaned thoroughly, re-assembled, new coolant installed, and the set will need to be focused, converged, and gray scale will need to be adjusted.

As far as I know, Marantz never had a DLP set in a RPTV design.

Because this is a common problem, I will be starting a thread with details about the problem and how to resolve it. Look for it over the next few days if you plan to DIY. If you will have it done by a tech, stay away from anyone who says that they change the coolant without taking the tubes out and without disassembly. This is not the proper way to solve this problem and is dangerous. Any drips or leaks that get onto a circuit board, the high voltage leads, or the yokes can be catastrophic.

Re: Marantz DLP repair


The blue glowing is most evident in a dark room. The image below is supposed to be a sharp blue rectangle on the screen. So, do you think this looks like contaminated coolant on the blue lamp? If so, I'll look forward to your DIY repair thread. Thanks in advance for you help!

Re: Marantz DLP repair


I would say that it is very likely, but it could be some focus related problem as well. The only way to know is to look into the lens with a flashlight when the set is off and see if the coolant is clear or cloudy.

Re: Marantz RPTV repair


I changed the title of the thread from "Marantz DLP repair" to "Marantz RPTV repair" to avoid confusion.

Re: Marantz RPTV repair


CRT Fungus and other issues are definitely out of my league. Have to bow out now.

This definitely looks like a focus or coolant problem. Have you taken the set apart to look into the lenses?
