Re: Won't Power On
As you have seen inside that no power & no light.
problem seems to be in power supply.
1 check fuse.
2 check switching ckt.
3 check for loose contact or print break.
4 now if you get power on & still tv is not ok then check for hor. output transistor in hor. output stage.
if you are not tech person please do not try to fix it as high voltage is there inside.

TV won't turn on • Press the TV button. Make sure the TV is plugged in.• Check the wall receptacle (or extension cord) to make sure it is "live" by plugging in something else.• Something might be wrong with your remote control. Press the POWER button on the front of the TV. If the TV turns on, check the remote control solutions on page 26.• The front panel controls may be locked (disabled). Use the remote control to unlock the front panel controls by selecting the Lock Fr. Panel in the PARENTAL CONTROL menu and press OK (box won't have check mark).Buttons don't work • If you're using the remote control, press the TV button first to make sure the remote is in TV mode.• The front panel controls may be locked (disabled). Use the remote control to unlock the front panel controls by selecting the Lock Fr. Panel in the PARENTAL CONTROL menu and press OK (box won't have check mark).• Unplug the TV for two minutes and then plug it back in.

I have a Sony SRS BBE Trinitron (WEGA). The last few days when I tried to turn it on using the remote the Red Light would go on but the TV did not turn on. I would have to press the power button again to turn it on.. I tought the remote battery was just low.
Today when I tried to turn it on nothing is happening and the Red Light is blinking 9 times ??? I tried to unplug it and try it again, still does the same thing ???
I would try a power drain: Unplug the TV's power cable so the TV is not grounded to the house. Then press and hold in the TV's own power button for one minute to drain the capacitors. Plug the TV back in and see what happens. If the TV will still not turn on, I would say you have a problem with the TV's mainboard as a dead power supply will not light any LED's for you.
Try these simple trick to find out yor remote control working or not....
Point the remote control towards the Camera of a Mobile Camera
phone,with the camera on. While pressing remote, we can see a light
(Infra Red) coming from its IR LED through the Mobile Camera if the
Remote is working. If the problem with the component that mentioned by you, write down the Number written on that and replace it with the same by the help of a Soldering Iron. Also see the writing near to it for finding out what the component is.... For eg. C=Capacitor, R=Resistor, TR or Q=Transistor, IC=Chip, D=Diode etc.
For the first one, please list the model number and count the blinks. Also, can you please post each problem separately. It will get too confusing trying to address 3 sets with different but similar problems.
