Mitsubishi Rear Projection TV Model WS-55311


Rear projection TVs are dinosaurs. Sell it if you can get anybody to buy it and get an HDtv they're pretty cheap now not to mention thinner, lighter and better for your eyes. Imagine the space you'll save if you mount it on the wall and the cost of electricity. Not trying to be a jerk but it's time to move into the 21st century. The picture is waaaaay better.

I have a phillips rear projection tv model no 55PP8620/79. Its showing a a red haze and poor picture quality. How do I fix this?


If the red haze is not convergence---that requires parts.

The set has three picture tubes---with set unplugged and back cover removed clean the three large lens that are topside---as for the red haze a quick way to know what is wrong is with set on turn the color to zero----what color is the screen? Should be black and white--if red to some degree tracking or screen controls may need adjusting inside the set---Yellow picture in that situation is a different issue.

The crack you hear could just be the speakers or a intermitant ground problem in the audio circuit more likely the spealers if its only on strong Bass

My 60inc phillips magnovox has poor color, what do i have to do?


we just bought a 55 inch phillips magnavox and told it was working fine when we got it home and turned it on it was a red screen and was really foggy. we looked up some tv repair places and ONLY 1 told us it was the picture tube and to look down them with a flashlight for bacteria! sure enough the green and blue had it. so we found one place that would sell us the coolant fluid that you have to change the others could get it in or wanted us to bring the tv to them. we did it our selves the stuff was $17.00 a bottle or if we took it in it would be about $375.00. we have a great picture now and it wasn't as hard as all the other repair places said.

Poor picture quality on my samsung HD TV


Hey xf1racer,

Based on the description that you provided, it sounds like you are using a bundled composite video cable to connect your cable box and TV. Composite video cables generally consist of three color-coded cables: one yellow, one red and one white. While the yellow cable is typically used to transmit the video signal to your TV, the red and white cables transmit the right and left audio channels respectively.

Red/green/blue bundled cables however, are often referred to as component video cables - each of the three colored cables is used to transmit a different portion of the same video image from one device to another, and require a second separate cable (typically red/white) to transmit an audio signal.

The primary benefit of using component over composite cabling is that many users may report a cleaner, more brilliant image on their TV as a result. Please keep in mind however that this is not a guarantee that changing from your current set-up to component cables will improve the picture quality on your TV, as picture quality is often based as much on personal preference as it is the actual configuration and settings of the equipment used.

Additionally, many retailers may suggest changing your current configuration to one using HDMI cables instead to improve picture quality even further. Unlike composite and component cables, standard coaxial cables, and S-Video cables which transmit analog signals, HDMI cables are designed to instead transmit uncompressed digital signals. This typically means that more information is available for your TV to process in terms of color hue, color intensity, as well as image resolution. Again, remember that any perceived improvements will be based on both personal preference as well as your home theater configuration.

Should you have any questions or lingering doubts, I would strongly suggest speaking with a Magnolia Home Theater agent at your local Best Buy™ store for more information. Most stores will have similar TV's on display using more than one type of connection, and sales associates are always able to provide additional suggestions if desired.

Hope this helps you out.

Sincerely,
Aaron
Go Ahead. Use Us.
