Re: 42LK450-UB Noob question

Most of the LCD panel spec show CCFL rating of 50,000 Hours.

Thanks budm so i guess roughly 6 years or so if running 24/7

Re: 42LK450-UB Noob question

in post 22 i did ask for the transformer part number but cant find any info on them, also in post 52 can you confirm if you did purchase a new invertor board and have tried it.

I did get a new inverter board and it did not solve any problems.

OK, he needs to check the resistance between:
pin 1 (bottom left corner) against pin 7 (top left corner)
Pin 1 (bottom left corner) against pin 6 (top right corner)
Pin 7 (top left corner) against pin 6 (top right corner)

At school now, but I will test this when I get home. So put a positive on 1 and neg on 7? Then so on?

We are checking the coil resistance so no polarity involved, and no power applied to the set, of course.
