Re: magnavox mwc20t6

DO THIS ONLY IF YOU KNOW YOUR WAY AROUND A TV.......... there are a lot of possabilty, but i would start at the crt board, there is 3 transtor there, q2503, q2502 q2501 check the voltage on them, they should all be the same give or take a volt or two, if you find one that is off voltage compaired to the other two, then....... pull the crt boad off the crt and turn on set, check the voltages again see if they check the same.
if the one that read diffrent still reads diffrent transtor is bad, if they all read the same with the crt board off the crt then the crt is bad.

All lines of convergence is wrong who I can restart adjusments?

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

No picture will talk, picture dark

If you mean you have nothing on the screen, either the backlight or its associated power supply has faiiled. Look at the screen at several different angles; if you can see some sign of motion, then the LCD panel itself is still ok.

Magnavox Model # MWC20T6

Manual will not help - if you unplugged it all night, and it will still not power up, try one more outlet in the house. If it still will not help, then you need to replace the power supply for the TV. Sorry.

Picture suddenly went dark

Hi, Apparently you have a possible component failure with your Panasonic PVQ-2510. This would involve the circuitry at the back/neck of the picture tube. Diagnosis would require familiarity with discreet components, use of a VOM, soldering and general component knowledge. In as much as it is possible that your red drive transistor (or an IC) would require replacement or resoldering, your best bet is to seek the services of a qualified professional. Should you venture to do a do-it-yourself, pls post back. Good luck and kind regards.

Dark Blue Screen

You might've done this already, but first I would try the "Magic Focus" The button can be found all the way to the left of the buttons panel on the tv itself. If that has no effect, try playing around with the settings within the tv. Click menu on the remote and see what happens when you try settings like color, balance, and contrast. Report back.
