If it's a clicking/pulsing noise suspect IK04 and IK05 the convergence IC's. STK392-150's. Don't forget to check the bias resistors.

Just changed Wednesday both convergence ic's ( sanyo STK392.150) and six resistors (RK-42,RK-62,RK-54,RK-58,RK-46 and RK-50). Noise coming some were in the middle of main board. Any idea or concerns? Thank You for your continuing response!!!!

Check C905 220uf/250v to see if it exploded and D918 to see if it's shorted. Also a common problem is a bad vertical IC. It will cause a dead set. No vertical deflection will cause a dead set. C614 in the convergence being bad also. Does the power light stay on?

Yes, Power light does stay on and all LED's are on both powerboard mounted on the side and main board on bottom.

Smack the crap out of S901. "Tap it with the handle of a screw driver" It's a relay that's notorious for failing. #FJ00142
See what happens.

minnie,
I am going ahead and replace these parts you suggested me to check! I got them online for a total of just under $14.00, let you know the out come.

Minnie,
I replaced the parts I listed in our previous contact to no avail. I do notice that the DP37 LED (red) dims located on the mainboard, it dims along with the clicking sound.

I hate to say it but, this one's going to have to be taken in. No easy button on this one. Sorry. I'll keep looking.

I know you suggested a repair shop for my problem, but got a fix on the clicking/chripping noise coming from LP06 (filter coil) that is in sync with DP37 red LED any last suggestions before I spend the big money? Shocked
