Triple colored ghosts


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. This is called convergence.

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,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

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

Red and blue ghosting,


The most likely cause is shorted convergence chips and possibly a few pico fuses.

Red ghosting


There is a bulletin that addresses this problem, but you must follow it EXACTLY as it invoolves changing settings in the service menu and you could easily make your TV unusable if you change the wrong thing. if you want the bulletin i could send it, but I would recommend you have a Sony qualified tech do the adjustment

If the red is colored outlines or 3d picture then it is a convergence problem.

If convergence is ok, then most likely screen/focus control assembly.

1.5 days after replacing both IC chips the blue started ghosting again and then...


The biggest problem you stated yourself. You bought aftermarket type IC's. You should have been smarter and purchased the correct IC's for the set. All IC's are not alike, even with the same number on them. Aftermarket IC's are just that. Built in China or are factory rejects. You might get away with replacing the iC's again from a reliable dealer or you might have messed up the power supply in the meantime. Good Luck

Red ghosts


red convergence went haywire... you need to relace I'm thinking two convergence ICs mounted on heatsink on convergence panel. replace both for usually they both blow replace any burnt resitors too, and hardest of all now you need to reconverge the whole thing.....which is a fine art.....u might be able to do it with the remote ...but u need a manual to go throught the steps really ..but not me i do em in my sleep. take it to shop unless your technical.
