Question about Toshiba 43H70 43" Rear Projection Television
I have had my 43H70 for about 8 years now and it seems that my picture is getting dimmer. I have increased the brightness level but no luck. Do the CRT's burn out?
After 8 years use, perhaps the lenses and mirror could do with a good clean.

Yes! CRT's do go weak with age and use. It is very possible that the CRT's are the problem.
The service tech can take voltage readings of the power supply, and biases to the CRT's to know if they are actualy weak.
From your description, I would thing very strongly that the CRT's are the problem.
