It seems that the micro-switch to turn on power is damaged. It can be replaced, and can be bought from most of the electronic spare part selling shops. De-solder out one among them as sample, because, pin configuration should be identified when you buy it. It wont cost more, a cheap component.
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!
Just keep smack'in it around, it works for me.
It is the 'protection overload circuit' taking over and shutting the TV set off. This is because it detected a short or near-short circuit somewhere. Most common is high voltage, deflection amplifiers and main power supply. It's pretty much a common fix for an experienced tv repairman. It might set me back in the ballpark of $200 - $300.
ok, Sony had this issue on their early production. The problem you are having is called a leaky switch. The volume down switch on the TV is leaky. To fix this you must replace the switch. This part is called the switch block. Part number 1-473-549-21
Aren you sure that the volume up button is not stuck in . It should feel just like the rest of them A little click? It could still be shorted,or the capacitor across the switch could be defective. If all this seems good then the eeprom, or the microprocessor,or the line or trace going to the volum button could be shorted. This is not a repair you should attempt unless your a tech. Now the button thong can be looked at after the set is unpluged and the back is off, gently slide out the chassis toward the rear of the set just a little and slide it back to see if the button is released. if that dosent help then you will need to take the set to The repair center. Good Luck
