Well you can tap the convergence board and the crt boards see if you can find a loose connection, however be careful there is high voltage

My samsung 61in. Dlp screen flashes green/blue pic is viewable but everything is the two colors, also screen will flash icon check fan #1


You have 2 problems. Problem 1 either you main board or light engine is bad and needs to be replaced. Problem 2 is exactly what your TV says. Fan#1 isn't functioning properly so a heat sencor is being actiated to shut down your set. Make sure all the fans are free of debree and spinning. If one is not spinning, make sure it has voltage going to it. This will let you know if you have a bad fan, or a bad board.

MY SONY KP41T35 PIC FLASHES ON OFF ON OFF AND GREEN PROJECTOR IS ON BUT NOT SENDING PIC JUST GREEN LIGHT


Sony PTVs do get bad CRTs, to confirm you can pull the front cover and tap on the middle CRT (green) neck with a plastic handle if the green screen flashes back to normal or brighter and causes the TV to shutdown then the CRT is bad. sometimes you can make it stay working for awhile, but eventually the CRT will need replacing. if this doesn't help you can turn the bottom middle control counter clockwise to lower the green .
hope this helps

Turns green and shuts off


I had an electrician come over. He pulled out the bulb that was dead (for me it was the color that was flashing before it would turn off) and now I have a blue and green TV with no red. He said that the only way to fix it is to replace the red lamp with a new one.
