A TV actually uses 2 different video processors. One for black and white, one for the color. Since you are missing color, you have lost the color signal. This could be a bad video chip, or a loss of power to the video chip, or a loss of signal in or out of the video chip. Re soldering the whole board is not reasonable. Have a tech track down the problem. It could be a loose solder point, maybe a bad component. Only a tech is going to be able to trace it.

Its the problem of loose soldering joins on the main board that has to be cleared to make this problem solve,
just dry solder whole board or get it done with a local technician.

The light is blinking a code. The code will be a series of blinks, a pause and the blinks again. Phone Sony service and give them this code. They will be able to advise you as to the problem.

there are 3 leds on the front that blink the error code. which leds blink gives you the error. if its just the standby/temp red led blinking, it has overheated for some reason. there are a couple other fans you could clean but check your ventilation. many people put too close to the wall or close it up in a cabinet. it needs atleast 4" from the wall and someway to vent out hot air and get cool air in. a different model had the temp sensor cause this issue, it is the silver thing right atop the lamp. you will have to pull the whole back panel possibly, there are two wires that hook to it and two screws holding it to the engine (lamp housing). if you get lamp and temp leds blinking, reseat the lamp door. timer and temp leds is a fan error, all 3 leds is a lamp error (lamp, ballast, colorwheel, dmd)

No picture, sound OK...setup menu shows up, able to get picture in PIP


You will need to check the inputs on the television. You more than likely have a bad video in signal. This can be a bad cable or a loose connection either at the input of your television or at the output from your receiver, (cable or satellite). First, try wiggling the cable and then try replacing it. This should fix the problem. If not, your signal may be routed through a stereo or other switching device?
