Has a double picture and looks rainbow


A double pcture with two different colours??? more seriousely the rainbow effect could be of an appature grill un hooked in one of the three tubes (THIS IS DANGEROUS IT COULD IMPLODE) you should have a proffessional looke at it and you should NOT USE OR MOVE the TV until then.

Good luck!

Good Day;
This is very odd for having only have of your picture scanning. Let me ask you a couple of questions:
1. Have you tried rebooting the TV by unplugging it from the a/c outlet for 4-5 minutes, plug back in a/c/
2. Have you moved your TV recently; maybe broken mirror?

Please try and let me know if I was any help; Good Luck, Big Irish.

You do not have a vertical problem, you have convergence concern. Try unplugging the TV for 5 minutes. If no fix call only an authorized service center. GOOD LUCK!

Bent picture


Not sure if you fixed your problem already. But the answer is a color convergence problem. You can try adjusting manually via the remote and if that doesn't work it is most likely the two main IC chips that control the color convergeance. It is also possible that not only the IC chips have gone bad but also there are a couple of resistors that usually burn out with the ICs as well. They will need to be replaced. This isn't something that I would attempt on your own. Typically a TV technician will charge between 300 and 400 to fix at your house.

SOUND NO PICTURE ONLY RAINBOW


I just fixed this problem on my neighbor TV. I don't have a manual or schematic, and didn't pay any attention to the reference designators, so I will just have to describe it. The problem was a bad solder joint. Visible thermal fatigue. Looking at the main board, (didn't even need to slide the cassis out). There is a small, narrow, vertical board in the center, adjacent to the yoke connectors with a funny looking little transformer on the very top. Check the connections on that.
