The real deal here is the protection circuit has activated. This is caused whenever an excessive amount of current is being drawn from the main power supply. Upon detection of same, it immediately takes over the power management of the set and shuts it down. The clicking sound you hear is the ON relay turning on the set, but immediately the power mangement system shuts it OFF. You should hear two clicks, but they may be so close together that it sounds like one click.

This set is getting rather ancient and I would not recommend you spend much money on it for this reason: It is highly likely that once the set if repaired that another failure would occur. This is because of the law of averages; the first failure is often followed by another failure from anywhere within the set.

Need codes for xfinity remote to work on memorex dvd player


  1. Turn on the TV or other device that you would like to program.
  2. Press the TV button on your remote control.
    NOTE: If you would like to program your remote control to work with a DVD Player, VCR or Audio device press the AUX button.
  3. Press and hold Setup until the red light blinks twice, then release Setup.
  4. Enter the first code for your device listed above. If you perform this procedure correctly, the red light will blink twice.
    NOTE: If you enter an invalid code, the red light will display one long blink and exit the programming mode. Repeat steps 2 to 4 with a valid code.
  5. Aim the remote control at your device and press Power once (press the Play key for devices that don't have a POWER button). If the TV turns off, make sure that the VOL+/- and Mute buttons also work. If so, you're all set!
  6. If not, repeat these steps using the next manufacturer's code (you may need to try several codes to find the one that works).

Did you check the service manual troubleshooting guide yet. You can try disconnecting the power to the inverter board and see if it will stay on and have sound.

Sony KV32FS120 Trinitron TV No picture or sound when power button on remote is turned off. Red light at front of TV blinks nine times per cycle.


Hello,

Once your television blinks about 9 times then it means there is a problem somewhere most likely the lamp of the television. Another source of this problem is also a bad capacitor from either the main panel or the power panel.

If your remote turns off actually it is because there is nothing to operate on the television, so once your television starts the blinking light, the remote will not be able to operate the television, once you unplug the television and plug it back then press the power button, the remote will do the same.

Until the television is fixed is when the remote will work normally.

Take care and good luck
