Flyback transformer


A flyback transformer is one of the more expensive components in a projection TV. If there is no clear reason, such as a known power surge, you could well replace the flyback transformer again soon because the root problem was elsewhere.
An OEM transformer is not necessary but you might have trouble convincing an authorized factory service technician to use anything but the original manufacturer's parts.
As with many of today's electronic devices, if it is more than a year or two old, you will find the new products cheaper and with more features. The next generation of projection TVs will use lasers and scanning will be done with optically controlled micro-mirrors - no flyback transformer required.

Having Problems getting my tv to turn on


It could be a Flyback transformer problem. Check th flyback for loose solder move the transformer a little bit and look on the underside of the circuit board. be careful ther may be current left over. Put your left hand in your pocket.or away from you. if it is not that you may have a faulty circuit board (burnt resistors) near the yoke going to the screen.

Could I possibly have a bad flyback transformer


I would try resoldering the flyback connections on the Circuit board. if the flyback was defective it would operate and you usually get 3 blinks on the LED indicator. Sounds more like a solder issue.

The lead going from the flyback to that other device is a voltage divider or splitter as they're incorrectly referred to... To remove the leads press down firmly, twist and then pull up...

Lamp issues


No its a tube and not a bulb. If thew line is green then theres an issue with the red and blue as the green is stationary on most sets unless thers a green centering ? Its a componet on the convergence board thats bad or going bad but if you replace any components on the board most likly your gonna need to do a convergence alighnment I would let a pro handle this repair unless your an experineced repair tech Good Luck
