Your set is totally different and it couldn't be a convergence issue. It appears to be an HDMI connection issue. Cleaning the HDMI terminals thoroughly will resolve the problem.To verify, use a different connection or hook a different device to a different input connection on your TV.

In case the problem exists in all of the inputs please let me know.

Replaced projection bulb 2months ago, now everything is pink and green...what do i do?


Sounds like one of your optical screens are out more likly the blue one. In rear projection tv there are three screens that converges on the frount display screen that makes up the picture you see. The three screens are blue red and green. It may be that one is out or is out of alignment. If you don't have good knowledge of electroncis especially high voltage circuits it would be best to take it to a repair shop to have it fixed. The price of repair can range from vary high to just a few hundred. It may not be worth fixing depending on model, type and brand of tv. There are a few types of rear projection tv. Most common are crt, lcd.

EVERYTHING IN WRITING IS DOUBLE AND THE PICTURE IS DISTORTED


Hello Tim this is a very common problem with the projection tv set, the problem is coming from the convergence board with faulty ICs that have to replaced in order for your tv set picture to work properly,they do sell convergence repair kits for your tv set but i would not recommend this the reason being is that if you make a mistake while changing out a component your whole tv set is gone not going to work anymore so for this i would recommend for you to call a near by tv repair shop and have a tech come out and change this ICs for you, after you change this ICs from the convergence board your tv set should go back to working normal on the link below you can check out how a convergence board looks like thank you hope this helps.

CONVERGENCE Problem cannot adjust ( green gun )


Compare your rgb voltages and your cathode voltages(green, red, blue) and also access your service mode settings. It might not be the STK-392-150 that is defective.
