Re: Continuous click noise like its trying to turn on but...
I have done some research and found a notorious cap and diode problem with this set. The two 4700uf caps (C14113 and C14115) on the DM1 power board (the board to the left of the sat. box when you look at the set from the back) are under rated and will eventually fail. When these caps fail they tend to take out diode CR14105. This may be your problem. If it is, you can replace the caps with 4700uf 25V 105c and the same as original diode.

yes this is a power supply problem. it has shut down due to a fault, for safety reasons, to prevent a fire or explosion. You need to get a "Quote" for repair. Please note, a unit such as this will more than likely be an un-economic repair.
It seems that your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done. It is that sound that gives it away, this is a typical switchmode Power Supply problem.
tv wont turn on when i hit power it makes the clicking noise like it is going to turn on, but never does and the red timer light next to the power button just flashes. help! trinitron kv29f1u only clicks and blinks
Well, I have found out that the number of red light blinks is a "blink code" that indicates the nature of the fault with the TV. Usually these are various failures of internal fuses or circuit boards. There's a fair amount of information on threads at techlore.com on this, so try searching there. Teh specific codes and manuals are usually it seems under license from Sony and not available for free to the public. Sorry!
The slight flash on the screen is usually because the CRT (picture tube) is holding a better than average charge and this is what we call "pre-glow" The noise that you hear, is that everytime you turn it on or just after it has been off for a while? If only after the set has been sitting off for a while then your noise is the internal degauser for the CRT and that noise is 100% normal. The degausers in Sony TV's are so strong they usually make the plastic cabinet vibrate a bit.
If you dont here anything then it sounds like the switching power supply or the horizontal output circuits not starting up. this requires troubleshooting with a variac, as well as maybe a scope. If your not trained to work on HI Voltage circuits you should seek assistance with this repair. Theres HI voltage inside these sets even after they are unplugged for a while. sorry i couldnt be of more assistance.
