Thats caused by failed convergence ICs and the 6.8 ohm resistors. You can get the repair kit called the DPTV305 -DPTV345 & MAG01 chassis convergence repair kit which fits your model. The kit has the components and the CD with repair instructions and its available at the following link top of the page. http://tvrepairworld.com/phillips__magnavox_repair_kits

SOURCE: I have a Magnavox 51" Projector TV. Model 51MP392H/17

Well I forgot to mention that when I do turn on the TV the button flashes 9 times then pauses for a second and repeats the flash 9 times over again.

Is this a error code for the 51MP392H/17 ?

Thank you
Joe

SOURCE: Magnavox Rear Projection 51MP392H/17 has ghosting

If this happened suddenly and the red and green images are bowed in at the center of the top, bottom and both sides, one of the convergence amplifier IC's has failed. The part number is STK392-120. Make sure it is a genuine Sanyo brand replacement; there are a number of cheap imitations out there that do not last. Generally they cost less than $30 each.

Note: there are two of these in each TV. They are notorious for having a high failure rate, so I usually replace both. (FYI: each chip has three amplifiers. Each color gets two amplifiers, so one color uses an amplifier on each chip. That's why we usually see at least two colors go out of whack when this problem happens.)

I assume you have already tried a different video source (DVD, VCR, etc.) to rule out input signal defects. If the problem arose right after the set was moved, either the optical alignment was disturbed or (less likely) there is a stray magnetic field near the set that is causing problems (magnetron from a microwave oven?). There is a procedure (sometimes provided in the owner's manual) for adjusting convergence using the remote control that can fix minor alignment problems. If you want to gamble it is not a hardware failure, try it first along one edge of the picture.

If you cannot shift the red or green dots in the convergence pattern, stop immediately, and make a note of where and in what direction you tried to move the dots. Inability to converge the dots is a strong indication the convergence amplifiers are bad (that is their job - to keep the colors lined up with each other). You will need to undo any adjustment attempts after you replace the convergence chips and any fuses or resistors that got burned when they went out, so don't make too much extra work for yourself or your service tech.

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 www.TvRepairKits.com

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.

For more more examples and find a fix using this link on Fixya http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

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.

yes its repairable
its a convergence circuit failure there are a couple ics and most likely some resistors that will need replacing and possibly a pico fuse

est 300 to 340 you mention only red and green though do you not have blue in your picture
id bet the blue is non exsistant and will need a blue liquid kit changed to correct that problem also

you might want to conatact a local servicer and give a model and ask them what they woud do both for then you can make a decision if you want to do it or not

Based off manufactureing timeline it sounds like you have some capicitors going bad you will need to contact a qualified Service agent for a service call to repair the problem.

Take the TV to a repair shop. It sounds like the convergence chips are bad. Be sure they change them as a pair or you'll wind up with the same problem again.

General post....
51MP392H/17

Actually I have this TV and you need 2 Convergence IC's STK392-120's (120's and 150's will work) of course order 2 of the same type I'm using replacement 150's they allow for a little higher heat and were cheaper ALSO you need to replace the 12 resistors with 6.8 ohm metal film resistors, make sure they are metal film! don’t skimp out here I did and then they blew and fried my IC's and I had to replace everything again!

Great reference link that I posted pictures on, check out page 3

Where I got all my parts that worked:
Suburban Electronics http://www.suburban-elect.com/

Manual Library you should find all you need here:
http://www.techlore.com/group/2/list_downloads



What you need:
(2) STK392-120 OR STK392-150 IC chips
(12) 6.8 Ohm Metal Film resistors
set of star screw drivers
15 watt pencil solder pencil, DO NOT use a high watt iron you will fry the surface mounted item.
good leaded solder, and flux


BTW if you don’t plan on trying this and are going to throw out the TV, I still need a IC convergence board for a 51MP392H/17 TV I'm fixing, I'm willing to pay S/H and buy your IC board that’s not been tampered with. Edwinkraus@hotmail.com

Sounds like your Convergence chips failed, were your red/blue/green colors slowly seperating or was the picture starting to curve on the top or bottom or both? if so see below general post.
Also what model # is your TV and what size?

Green screen


It sounds as thought the lower light strip has malfunctioned & blown the red/blue LED lights leaving only the green bulb functioning, I would ring the makers repair team for a repair if it's under warrentee or a repair quote, if warrentee has expired, from my personal experience showed me that a new TV is cheaper. I hope this helps.....

Yes,semiconductors is the term used to describe transistors,diodes,intergrated circuits(IC's)etc...the correct generic part# for that model is STK392-120 which is an intergrated circuit (IC)which in that TV works as a convergence amplifier.The specific Philips part# is 932212344682. There are two of them you need to change both. Also check the two 6.8 ohm resistors nearby if they are burnt or discolored.
