Convergence without a remote

Hey I have never done this before so I hope someone can help me.  We have a big screen magnavox bought about 3 years ago.  before we moved it began to have shadow figures on it and I didn't know what to call it but now I see it is the convergence thing.  It has the red and green and yellow shadows like there's 3d going on.  My problem is I don't know how to get to the convergence menu.  We lost the remote several years ago.  Could someone help me maybe tell me how to get to it or do I just need a service man?  Thanks so much for your help, Sincerely, Kelli

First off, you do need the original remote to adjust the convergence, Second, the service mode will not fix your problem. If the colors have all drifted, you have a problem in the convergence drive circuit. Most likely the convergence IC's are bad or going bad. The service menu is not a fix all for the problems with the convergence. The service mode will or can make minor convergence adjustments,not anything where all the colors are off. If you have no solid state repair experience, call out a service person to assist you in this repair. Good Luck

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

Hello linda, hi, I dont think the remote or manual can help the color issue problem, the tv needs to be looked at by a qualified technician. If the TV is a tube type, there are magnets on the neck that needs alignment, this alignment is done while the TV is ON. so high voltage risk are likely. keep out and call service.

I have a Mitsubishi VS-60607 Tv and it started out


Without going in with troubleshooting equipment it is hard to determine if the problems are related or not but it is unlikely since you seem to have a video problem and a convergence problem , which are two separate circuit(signal processing and deflection). Hope this help.
Please do not rate this answer(unless it helps)as it is only a suggestion.

Concave tv screen colors distorted just had tv repaired one year ago for same problem


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.

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 from the link below.

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 - TV may also make a chirping noise.
Here are some photos of convergence problems.

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.

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 solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Picture not centered on my philips 47'' lcd tv


NOTE:(Edited and copied from another thread on Fixya.com, c7carl)

Picture is not centered on monitor leaving a 2 1/2 inch; black border on Philips LCD
By dmorrow54 on Nov 13, 2007
Again, nothing in manual for Philips LCD will correct the fact that the picture in HD-D mode will not center. The picture runs off the monitor on the left (facing the monitor) with a 2 1/2" black border on the right (facing the monitor). Using the format button on the remote of directional arrows will not correct the issue. The wide-screen/ full-screen function with format does nothing. Moving into TV mode, the format function works to display screen in several ways 4:3, 19:2, super-zoom, wide-screen, full-screen. Help, please. posted 3 years ago

I have a Philips 30 inch LCD and solved the problem by using the circular arrow button on the TV remote. Pointing it at the TV and clicking "right" (3 o'clock on the button), the picture moved right. Same thing on for "left". Worked for me.

My philips magnivox rear projection TV has a cloudy picture..is it worth fixing


Yes, I used to work in Best Buy and one of the key things about rear projection TVs and the reason they push those service plans on you is that the tubes/colors need to be calibrated each year. You can do this yourself by checking out the following website:  

http://lgknowledgebase.com/kb/index.php?View=entry&EntryID=3229 

If you are not able to adjust the convergence using the remote you will need to replace the convergence chips. 

Typical Symptoms

1) Convergence menu does not work for one or more colors.  
Such as: Red moves up,down, but left or right fails. 

2) Screen is bowed looking.

If you have one or more of the problems above you need to replace the convergence chips. You can get a kit and instructions from www.TvRepairKits.com  

Hope this helps :)

BIG TROUBLE with my 52" Phillips Magnavox Rear Projection Tv, HELP!!


It sounds like the 3 "GUNS" are not aligned.
One the controls at the bottom, left hand side You will see an arrow pointing to the first 2 on the left.
That will allow you to scroll down the list of options until you see....CONVERGANCE!
make the red gun center by using the up/down arrows on right. Then add the next 2 until you see a white X or cross.
Thats it!

Tilted tv screen


The complete convergence for the Philips projection sets usually requires a clear plastic overlay which fits over the screen and has many precisely spaced black dots. The remote is then used to enter the service mode and converge all 3 colors onto the dots, and then the settings are stored in an EPROM IC. This should only be done by someone with experience with the Philips sets.
