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.

My RCA Truflat T.V won't turn on and the FPA lock is turned on, I have the original remote. what should i do?

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. Turn the TV on and try again.TV turns off unexpectedly • Sleep timer might have been activated. Go to page 24 for instructions.• KidPass might have been activated. Go to page 21 for instructions.• Wake-Up timer turned on the TV and no remote or front panel buttons were pressed for two hours.• Electronic protection circuit may have been activated because of a power surge. Wait 30 seconds and then
turn on again. If this happens frequently, the voltage in your house may be abnormally high or low.
• Unplug TV. Wait five minutes. Plug it in again.

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 ???

We need help...

Power problems problem on

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.

Tv wont turn on

take your tv to technician who can check your power supply, if your power is coming on and off, than a problem is not as big. firstly let him check a ht of a supply constantly, your supply is cutting.

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.

Power button Flashes

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.
