Magnavox 51MP392H/17 51" Rear projection tv. Tried to converge the colors using the remote, but it appears that the red projector needs adjusting. Is it possible to remove the back and adjust it at home? I'm quite handy!

No, if the Red doesnt adjust with the remote, You will need to replace both STK392-120 Convergence ICs. Its a fairly easy job if you have basic soldering skills, and you will also need about four 6.8 ohm 1 watt resistors for your model. You can get replacement ICs and resistors at the following link and they provide free instalation instructions with pictures. Heres the link.

Currently, the red and blue color alignment is off and I am unable to adjust this. There is a red shadow with a blue hue. Have tried to realign the colors but can not get the red to move.

How do i reset the convergence on my rear projection tv


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 photos of convergence problems.

e87380c.jpg
Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

Magnavox 51MP392H Rear Projection Television convergence problems


You need to try to adjust it with the original remote in the TECH mode---you can save the adjustments there--

With the set on a video input with nothing connected:
hit the following buttons: 0 6 2 5 9 7 STATUS

The menu should appear with choices---green(do not adjust green) red to green, blue to green etc.

On that initial menu will be a item that says store or save. Depending on the remote you have once you select red to green (cursor on remote) a grid of lines should come up---on screen will be instruction--menu to adjust and or status to navigate.

When you have the red--to green adjusted hit the status button until it takes you back to the menu where Store or save is listed and right cursor on it.
This will store the adjustments.

Go back by selecting blue to green and adjust that also and when done go back and save it.

Turn the set off to exit the service mode and see what you have---IF THE SET DOES NOT RETAIN these adjustments made in the Tech menu something is wrong with its DCU--digital convergence unit---that stores the adjustments.

Magnavox 51" Projection TV Red Convergence


he is most likely trying to rip you off. You need to replace the convergence ICs. Theres a kit at the following link for your model that has both ICs and the 12 feed resistors plus step by step instructions to do the repair. Heres the link. this is the kit your model uses. http://servicemanuals.vstore.ca/product_info.php/pName/phillips-dptv-305-dptv345-convergence-repair-kit/cName/convergence-repair-kits
A convergence problem such as your describing can blow a fuse if you try adjusting it when the ICs fail. and its all centerd on the SSM panel the LSB panel wont be affected. Alot of TV repair men dont have a clue they just try to sell you some boards instead of repair the issue.

TV- rear projection


If you try to adjust this you will make more work for yourself. The problem is convergence amps go bad and anything you adjust now has to be readjusted when problem is fixed. Also, convergence problems are a very common problem in all brands of projection televisions, not just magnavox, because the amps run pretty hot holding the colors in aligment. It's unfortunate you had bad luck with this set but we are also now seeing LCD, DLP and PLASMA sets that barely make it through the first year. More and more brands only carry a 90 day warranty now, so they know the life span is decreasing. To repair your set you will need soldering/desoldering equip. and test equip. or you could pay someone with experience 175.00-375.00 to solve your problem for you. That's why we're here. Lots of luck, Russmann.

51 magnavox projection tv-color mixing wrong


The are controls on the inside of the tv above the circuit boards for focus and to turn up intensity of the projector lamps (red, green, and blu). If you turn it up too far all three projector lamps kick off. If this happens, power off the set and turn down the lamp that you turned up. Power it back on and slowly turn the projector lamp up until the picture looks OK. You have to take off the panel on back of set to get to the controls.

Bad color


Your TV most likely has one of two possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • 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.

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

2c07611.pngSolution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


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.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.
