It sounds like the color settings are out of whack, try going to the tv settings and reset them back to default. Then try changing the Red green blue values (RGB) in the color settings, simply lowering the red value might do the trick

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

Hi. My Sony Videoscope XBR's Convergence Allignment


I happen to share this same problem. The alignment of the gridlines on the standard convergence panel are completely abnormal, and if I attempt to auto-adjust the TV, it flashes different colors on the sides of the screen , and then turns off the convergence settings.

Convergence on my panasonic pt47wx53g is out of whack. tried setting to default and tried the convergence steps in book. neither worked. red is especially bad. everything looks to have 2 heads 4 eyes...


Did you try the service menu convergence options or are you talking about the basic conergence steps in the manual?

I have had this TV for going on 9 years and would be happy to walk you through the steps.

55 inch mitsubishi rear projection tv red lamp out of adjustment


Have convergence IC's replaced. I believe this unit uses STK-392-570 convergence IC's Only one has gone bad but replace them both, because if one has failed then the other is not far behind, for Blue and Green. One handles Red, One handles BLUE and Grn. There are only two of them in the set, They are the two largest IC's in the entire set.

Have you tried to do set the convergence with a pattern on the screen? Some tv's have the pattern built right into the setup. Others do it auto just by pushing a button. Adjusting the pattern on one side of the screen may affect the other side, depending on how far out of whack it is.

Magnets (speakers) near by will play havoc with convergence.

No blue auto convergence when performed by menu buttons


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded over.

Convergence


Touch-up Convergence adjustments Enter the Digital Convergence Mode (DCM) by entering 0-6-2-5-9-7-(Status or Index) on the Remote control. The following menu will appear: Select an active channel or Aux Input. A signal must be applied to the set when performing convergence. If any Customer Adjustments need to be made, the Menu button can be used to toggle between the Customer Menu and DCM. The MPOSD ADJUST is used to center the Customer Convergence grid. A highlighted cross will appear along with the Convergence alignment grid. The highlighted cross should be centered onto the center of the Convergence grid. To perform a Touch Up Convergence, highlight SELECTION and press the right cursor button on the remote. The following menu will appear: Selections STORE, RESTORE FACTORY, and RESTORE DEFAULT are not shown after selecting SELECTION. Press the cursor down button on the Remote for these selections to appear. RESTORE FACTORY loads Convergence defaults from the Factory Loaded section of the Convergence Memory IC. RESTORE DEFAULT loads Convergence defaults from the sets software. To perform a Touch-up Convergence: 1. Enter the Convergence Mode and select RED TO GREEN or BLUE TO GREEN. Do not select GREEN (Green Geometry) without placing a Template over the screen. To perform Green Geometry, refer to the Complete in-depth Convergence. 2. Use the Cursor buttons on the Remote to Navigate from one adjustment point to another. Press the Status or Index button on the Remote to select ADJUST. Use the cursor buttons on the Remote to adjust the Red to Green or Blue to Green. Press the Status or Index button again to navigate to the next adjustment location. 3. After Convergence alignments are complete, press the Menu button on the Remote to return to the SELECTION menu. 4. Highlight the STORE selection and press the right cursor key on the Remote to save changes. 5. Use the GREEN TO RED or GREEN TO BLUE selections to perform convergence when the Green CRT has been replaced.
