HLN567W DLP TV - Component pix perfect - Analog inputs have RF type lines in pix - Lines get less noticeable as TV warms up. Help!

Sounds like the digital board, could you be a little more specific or can you take a picture of what it looks like so we can be sure.

They are diagonal lines that float thru the pix only on analog inputs. They start out large and get smaller as the TV warms up. Sometimes they are stationary and other times they drift up or down thru the pix. I was thinking it must be something common to all analog inputs - Like a power supply problem.

Negative, I don’t think it’s the power supply, if it was you wouldn’t get any picture at all, check the digital board for any swollen capacitors at the top and replace them, if not then buy a new one and replace the entire board, good luck.

I'll try the caps - Thanks for your help!
