Re: wavy lines

I have the same problem with this tv. i took it to a tv repairman, and he told me my convergence circuit board was the problem. the circuit board itself is about $300 and the labor to fix it is another $150. So i never got it fixed, cause it's just too expensive.

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

My picture is warped or bending in the middle

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

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Your TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

Red and green lines on picture only in the corners of the pic

YIKES, I dont know about Coolant changes but I'll post my general post about the 51MP392H/17

it has links to the SERVICE MANUALS and info to other sites that might help...

GOOD luck

General post....

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

Manual Library you should find all you need here:

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.

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

Hello bullmuscle,

This is a power supply problem, I would suspect the HV power supply because the primary and secondary supplies anymore are tied to the HV power supply. This type of repair requires certain pieces of equipment, to test voltages, look at signals, and to if need be test for shorts in inductors (Switching PS transformer and Flyback transformer). I would not recommend that you try to fix this yourself, The cost for this type of problem is not that expensive and can be done in one evening, if the parts are available. You may be fortunate and it could be just a blown fuse, in the HV or LV power supply circuit

I hope this helps,

Thank you,

Magnavox television

Basic TS - Turn tv off and unplug from wall outlet for 30 seconds. Make sure cable or sat box mute is off. Turn back on. If still no sound, just make sure that a dvd player, vcr or anything else connected to TV has no sound. Check antenna as well as cable or sat channels. If nothing has sound, call a serviceman to check out.
