Re: tv won't turn on?
The main power supply section is not working.
(standby supply is OK)
Common possibilities are:
- High-voltage section (flyback transformer) has failed
(happens sooner or later, about 8 years typical))
- CRT tube has failed overloading the supply
- Power surge has popped the power input circuit.
(Fuse, rectifier diodes, turn-on relay etc)
- One of a hundred of electrolytic capacitors has failed
short overloading the supply. They dry
out with age, are cheap to replace, but hard to find which one it is.
- Or any of many other possibilities.
In short, you need a experianced tech to troubleshoot this.

If the TV does not turn on or off, does not respond to the remote
control or the control panel buttons, or has audio but no video:
1.) Press and hold the POWER button on the control panel for ten seconds. The TV will turn off.
2.) Power on the TV and the green LED will flash quickly for about one minute. The changes you made most recently, before using SYSTEM RESET, may be lost.
If the TV does not respond to the remote control or to the control-panel buttons and TV will not power on or off.
• Unplug the AC power cord for 10 seconds.
• Press and hold the POWER button on the control panel for 10
seconds to perform a system reset.
If the TV turned itself off and the light on the front panel started to flash:
• Momentary power fluctuation can cause the TV to turn off to prevent damage. Wait for the green light to stop flashing and turn the TV on again.
• If the TV does not stay on, press the POWER button on the
control panel for ten seconds to perform a System Reset. If this happens frequently, obtain an AC line power conditioner/surge protector.
• An unusual digital signal may have been received, triggering a
protection circuit. Wait for the light to stop flashing and turn TV
If the TV will not power off, press the POWER button on the control panel for ten seconds to perform a System Reset.

I would not recommend using compressed air or any other method that would blow dust around- since the dust could make its way into the set's circuitry via the grille or vents and cause problems. Use a vacuum cleaner with a brush attachment instead.
ok, this may be a silly question but when you turn it on and it starts flashing red, have you tried pressing the stand-by button on the remote. if a tv has been put on stand-by by the remote, and is then switched off by the set, when the set is turned back on it is still in stand-by mode and you need to press the stand-by button on the remote. other than that I don't know.
some tv's always have standby light on, even iff you turn off by tv button. solution 1: with light on, press a number on remote. solution 2: with light on press stand-by button on remote. solution 3: with light on push the 'on' button on the tv set. solution 4: unplug tv set, wait a few seconds then plug back in, if no light then turn on tv using button on the set, and then channel number.
If you don't have a code follow this auto search mode, this will automatically search the remote control the code of your unit.
1. Power on the unit(TV).
2. Press and hold SET key and TV key at the same time. The led light will be on at the moment, then released the pressed key.
3. Press the SET key again, then release it. The led light will flash and it is in the quick search mode.
4. Point the remote control to the TV, then press the POWER key(every second) until the TV react.
Once the TV reacted try the other function key.
Repeat the steps until you've got the right code.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
Press SET BUTTON and at the same time, the appliance you want to set( TV, VCR,Aux...etc). The LED should stay on.. then press on the SET BUTTON again ... the led will blink fast... then press ( in front of TV, of else).. the POWER BUTTON to see what happens, if nothing happens, then press the +CHANNEL BUTTON once, and press power again. Repeat this until it turn off. Then press the appliance button (VCR,TV,AUX, etc...), this will stop the LED to blink and your appliance will be set.
Not sure if you've decided to throw your remote control away already or not. But try using the manual search code. Basically press "TV" (light blinks once), then press the "Up" channel button and the "up" volume button at the same time (light comes on permanently), then hold down "Power" whilst putting the remote RIGHT IN FRONT of the place where your tv receives signal (usually where you can see a light), and I mean right in front! Hold it down until your tv powers off. Then it should be configured and working. It took me about 1 minute or more for the TV to react and turn off. Then you can check if it turns on again and if the channels are working.
The codes are, 0145,1145,...Step 1. Turn the TV on. 2. Press the TV button. 3. Press and hold the SET button until the LED blinks twice, then release. 4. Enter one of the four digit codes, the LED will blink twice. 5. Aim the remote at the TV and press the POWER button, if your remote does not have a power button, press PLAY, the TV should turn off, if not, try steps 1-5 again using a different code....hope this was helpful...
