What is convergence IC problem


Convergence has to do with how different colors are displayed on a screen or monitor - typically the rear projection and some other types. When colors are overlapping to create unexpected combinations, or leave gaps between areas where overlapping is expected that results in a shifted red, green or blue image strip or edge - that is an indication of a convergence issue. They can look like this in severe cases:

Colors will drift, so manufacturers often include a utility to help you nudge the colors back in the right place. Most times this utility is buried in the Set Up Menu and when activated, produces a screen like this:

6c0170ed-2cd6-4dfa-bbcb-a10a7d20f92f.jpg


You will need to adjust the red, green and blue colors for each cross so that only a white cross is displayed. Keep red, green and blue fringing to a minimum. When you're done, the screen should look black and white, symmetrical and straight - like this:

Problems arise when you are no longer able to coax the utility to give you these crisp, B&W results with no red, blue or green ghosting. This is often due to a failing convergence integrated circuit ("Convergence IC"). Many times, replacing it will solve the problem, but other times it can be the result of failing components either ahead or after this IC. If you're attempting to replace this IC, please make sure the TV or monitor has been *unplugged* for 24 hours or more to allow the dangerously high voltages to dissipate.

your convergence settings are moved and they need to be adjusted and if you adjust and still have the problem then its the problem of convergence STK ICS and they need to be replaced.

Change element tv from 480 to 1080


The TV will play whatever signal (480,1080 etc.) it is being given, that is to say if you have 1080 available that is the resolution it will switch to, so there is not anyway to change this.

Panasonic pt-47wx53g red is out of convergence range


Have you moved the TV recently?, if so the red can(Red source) in the back bottom of the TV may have physically shifted in its holder, this is common when a rear projection tv is moved, jostled. Take the back off, look at the three cans,Red, Blue, Green, see if they all look like they are nested the same, bet the red is shifted a little.Good Luck with it!

Mitsubishi 55411 projection tv has red band across bottom


go into the customer menu and select convergence with the original remote; if either the red or blue will not move in some direction, you have a bad convergence IC(the WS-55411 uses two STK-392-110 CONVERGENCE IC chips)

Red Green Blue Across The Screen


Yes, especially big screen. It sounds like convergence is out of lign. Try menu and straighten out, wait until set is warm first.
