I have a HCM4216W rear projection tv. It was


The convergence IC have gone bad, bad solder connections to IC or probably both. The board as a whole can be purchased as complete (look to the web to find where to get) and is fairly easy to replace. Unless you have extensive experience with component level repair I would suggest you take the board to a TV shop to repair. This option maybe slightly less then replacing board. Check with your local TV repair shop to see which option is the best in your area.

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

Sony 65 inch screen tv


The lines you saw, i;m sure they are the ones called retrace lines but know the failure could be located on the red CRT board. Most likely the video amplifier is defective and not necessarily the CRT.
What is the model number of your TV?

Green Flashes - Shuts off


Sounds like the green picture tube is defective. To confirm you can take the front grille and door off and tap the green tube lightly with something plastic, and not to touch any of the adjustment controls to confirm.
