RCA F36650 Chirping

This is an RCA Model: F36650 Chassis: ATC113CA1
When TV was plugged into the wall it made one click, which is normal I think.
Press power button, the power light came on for 1 second, went out, then came back on for another second, went out, came back on, went out. In other words, it would try to power up 3 times with one press of the power button.
I think something else has gone out while attempting to troubleshoot.
I powered it up with the 2 wire plug with red and green wires(deflection board?) disconnected.
It had the same symptoms as above, but 10 seconds later it started making a really fast high pitch chirping noise.
At this point, it does this as soon as the TV is plugged in. There is no solid click after plugin now. It just chatter chirps. Power button has no effect and does nothing to change the sound.
DP80 gets hot while this chatter chirp is happening. I measured 160 degrees F and climbing before unplugging the TV. Removed DP80. It checks good with diode tester.
Plugged up TV with DP80 removed. The loud chip chatter is gone, but can still hear high voltage hiss around LP03. No solid click at plug in.
Removed TL02(HOT?) . All 3 legs measure dead short between each other.
Plugged up the TV with TL02 removed. High voltage hiss still around LP03. Still no solid click at plug in.
If I had just replaced TL02 at the start, I am betting it would have fired up. Since the initial plug up click is gone, something else is popped. What should be checked next?
