Screen on 42 inch green after patch to resolve other problem

I have a sony grand wega, I had a sony tech come and install the patch, (the tv was going on and off), he installed the patch, when the tv came back on it looked yellowish/greenish, so I ordered the new bulb, that fixed the on off problem but it is now greenish, could that be from the software install and what are my options for fixing this? How much is an optical thing and it sounds expensive

Hi

The problem is that your Convergence chips(IC's) (amplifier chips that send a signal to the projectors) are shot. The typical cost to get this fixed by a pro is about $300 - and it doesn't mean that he/they will do a job better than you do. The parts are less than $100 (about $20-$30 for the IC's) if you want to do it yourself. Replacing only the IC's MAY solve the problem; however, many people have also had blown resistors requiring replacement. Why would you ask should you replace both of the IC's if only one is shot?! If one is shot the other one is not far away and for that little price of the chips it worth changing them both at the same time. Also the convergence board should be checked for cracked solder. If you replace the ICs and the resistors are shot, the ICs may blow again almost immediately, meaning you may have to do the repair twice.

Please do accept the solution and revert for further assistance.

Thanks
Rylee

Check the options of contrast or tint, if your adjust them to your preferences then maybe it will work, or maybe it is just old. Glad if I helped.

I hate to say it, but your Optical Block aka Light Engine is going out on you. Sony has been extending Warranty on these since they have been so problematic, but this has been on a case by case basis. Your best bet is to call Sony and keep at them. If this gets you nowhere, it will not be cost effective to fix.

If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

Please make sure that the videos sources are connected properly to the TV.

Try Power Resetting the TV.

Please disconnect the power cord from the wall outlet (for approximately 1 minute), then reconnect the power cord and check whether the issue is resolved.

Also try connecting the TV to a different wall outlet and check if that helps.
