A common cause is a short occurred in the electron gun of the CRT. This usually causes collateral damage to support components in the CRT drive circuits.

The set will require proper shop service to determine the exact failure. I personaly would not invest any money in a set of this age. I would consider replacing it with a new LCD type.

Tv just shut off, so i un-pluged it for a few, turned it back on green light flashes for about 20 seconds then red lamp light flashes, tell me the bad news

Yup.. it's bad.. sounds like a typical Switchmode power supply fault or some other fault that is shutting down the PSU, to stop any more problems and prevent a fire etc. I guess it cannot hurt to obtain a firm "Quote" for repair from a reliable service center?

Toshiba 50H81 Sound but no picture

if you heard a pop that would be a capacitor unable to take the voltage, hopefully no other damage, you will need to identify the capacitors that have gone and replace the parts with the same number ie 40v 300uf 105c remember don't touch the 400v or 200v capacitors as they will still have power in them, discharge them by placing a metal object over the + and the - on the capacitor and then the board will be safe.it could also be the bulb has gone. you would need to check this as if the bulb has gone the tv will shut down. and flash but usually there is an led that flashes to tell you bulb failed.

Tv is pluged in,will not come on when on button is pushed

is the unit competly dead? no flashing lights.first unplug the set for 30 min then plug back up and try again if there is no lights then i suspect main fuse has blown. however this does not mean replaceing will fix. something has shorted to cause fuse to blow if there is flashing then the computer in the set has seen something wrong and shut down.

Av-32d302 tv

The set is shutting down because a problem has been detected. Replacing the remote will not help. Count the flashes and call a JVC servicer to get an idea about what the specific problem may be.

Lcd sharp tv flashing green light

Try unplugging the unit and while unit is unplugged hold the volume up button and channel down buttons down and while depressing both buttons plug the unit in. Let go of the buttons and the unit should come on in the service mode. There will be a small k on the screen. With the sharp remote press the channel up button once. This should bring up a menu that will show a lamp error line. If the lamp error is = to 5 the unit is in lamp error shut down. User channel down to highlight that line and curser right arrow to highlight the lamp error #. Hit the enter button to clear the lamp errors. Now unplug the unit and let it sit for a minute and plug back in. I hope this corrects the problem. If the unit does not come on by doing this or if it does and you do not find lamp errors the power supply pcb may have been damaged by the surge.
