Question about Philips Magnavox 51MP392H Rear Projection Television

1 Answer

Magnavox 51MP392H/17 picture is washed out

Teh picture on my set doesn't have very good color. The manual convergence blue has a haze around the +. The picture is pretty sharp (Not the best though) But the color is almost like watching B&W at times. Is there something I can change? Thank you

My tv is a magnavox and we bought it about 3 years ago and it is now showing like a double picture the color is hazy and pinkish looking the model is 51MP392H/17


The problem of your unit is the convergence. Try to adjust it using the original remote control in the setting menu, then goto the convergence section adjust the red and blue convergence, you should move red and blue UP, DOWN and LEFT or RIGHT, if you cannot move them far enough the convergence IC is defective, replacing this IC will restore the original setting of your tv. This convergence IC is attach to a large aluminum plate it is the heat sink this IC has a marking of STK-#### followed by numbers, remember be careful when replacing this IC you may accidentally tampered or damage the PCB and cause much damage to your unit. Or you can contact a technician to do it for you and save you from stress good day and best regards. Try to check this link for the convergence http://www.google.com.ph/search?q=convergence+ic&hl=tl&sa=X&tbm=isch&prmd=ivns&bav=on.2,or.r_gc.r_pw.&biw=798&bih=472&ech=1&psi=JZdtTvDCPIe4iAe72sTABA.1315804977740.3&emsg=NCSR&noj=1&ei=MpdtTpa4OKKSiQfBpcjGBA

Convergence wont align on Magnavox 51MP392H/17


You will need the original remote to perform a convergence touch up on Magnavox TV sets. If you are using the original remote - but still can't get it working - go back to the site where you purchased the tv repair kit and ask for their help

Blue haze on the lower part of rear Projection TV


Your TV most likely has one or more 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.

Here is a quick test....

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.

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.

White looks blue


usually there's a HUE setting for color problems. try to go and play with the HUE whih is usually beside the contrast, brightness....etc.

if that didnt work, then there's a problem with the deflection coils focusing, either from shipping or a hard hit. if its still under warranty send it back for repair.

let me know if that helped, good luck :)

yes your model has the 6.8 ohm 1watt resistors there are 11 of them often marked as 6R8 1wJ instead of color bands. They are resistors 3149 through 3160 you can get replacement resistors at the following link.

Blue Color Convergence wont adjust


yes by all means . I will post a link where you can get your replacement ICs along with free installation instructions with pictures. They also provide free on-line instant messaging while your doing the repair which only takes about an hour from start to finish. I am one of the support techs. Your model uses STK392-110 or STK392-120 either IC interchanges with each other except the 120 is a better IC runs cooler.Heres the link.You will need to replace both ICs

Blue Convergence just went out?


High Voltage Capacitor? Leave the set unplugged for 1/2 hour most components will selfdischarge, as for your problem, being a Magnavox, you have one of two problems, the convergence I suspect is what is blown out, this unit probably uses STK392-110 Ic's, I would suggest replacing with STK394-160e chips as they are probably shorted, some of the big resistors (1 or 2) may be opened up also, usually they change color. The only other thing that would cause usually a yellow color in the corners is the CRT Fluid, it changes from clear to Orange in color and clamps off the blue color from the fringes, I suspect the chips need replacement, dont forget to put some heatsink dope behind them, they are usually on the left in the front of the set (from the back) Big long heatsink that is fairly tall (probably the biggest heatsink in the set.) Good luck, and the repair usually runs around $350.
