SONY rear projection TV - Whites have started looking "snowy"


This is your Picture tubes getting very weak.( low in emission ) You have three in there and I guarantee they are no longer available so I would start thinking about investing in a new set, but use that one until you can't stand it anymore.

The screen is not clear


Grainy image = playing standard 480 cable or antenna on a high definition set

Double image - convergence ic's, or circuit

Green shadows - green crt coolant/tube issue

Since i haven't heard back, i'm going to clear this from my queue

sounds like some of the 3.9ohm 1 watt resistors are open some will get destroyed when the ICs go out and you can tell by looking at them they need to be checked with one side unsoderd and lifted from circuit

Pink screen


Pink and grainy almost certainly means CRT coolant leak on
signal PCBoard. Unplug set from AC, then take off lower front
cabinet. With good light, look for liquid spill on PCB.Touch it,
feels heavier than water,but not oily,clear color.Repair would be
expensive,requires replacing at least one CRT + clean PCB.
Most likely,the green tube is the leaker.........T.
