I need to know first if your TV is on standby mode (red LED lit) or not?..If the green light lit your TV your high voltage (HV) is switch but you have open line on heater that cause of no picture and the sounds is chirping because of analog(antenna)/digital connection or bad audio chips..
I need this information above for specific diagnosis and to prevent more damage and failure..Also I need this information to avoid mistakes to buy a parts with no help...
also I need the model # because on my tread there are 2 model # which are correct? is it 60PP9202 60" or 55PP8620?..for specific diagnosis and for possible get a diagram..
The deflection board needs replacement. The chirping is indicating the deflection circuit has an issue. You can get a replacement deflection board from www.tvrepairworld.com which includes instructions on how to remove and replace the board.
Without examing the set. IN general as a techs when they hear chirping noise is an indication of what is know as a Bad Flyback transformer; You may possibly have a shorted Horizontal Output Transistor or both that will need replaceing.
NO - - signal did nothing to the set... Sounds like a shorted HOT (horizontal output transistor) and the feedback your hearing (chirp) is on the horz. transformer as it tries repeatedly to startup... Don't allow it to do that for too long...
That usually means a problem in the start up or deflection circuits. Diode, Horizontal ouput or driver transformer. What Chassis is this set, and I will be ableto give you some better information. Rca , GE and phillips need to be diagnosedwith the chassis number. Let me know the chassis.
