Do you have heater voltage because if you are hearing high voltage you may need to replace a resistor and capacitor in the 200v circuit or you could possibly have a anode not seated right arcing on somthing or a bad flyback

have you tried a power reset, unplug all components from the TV unplug it from the wall, then push and hold the power button for about 30 seconds, then plug all components back in, plug it into to wall then turn it on again.

Magnavox 42 LCD 42mf438b/f7 turns on/off by itself


Mine was doing the same thing. Update the firmware and it fixes the problem. Updating the firmware is done by downloading the file to a thumb-drive from the phillips product support page then plugging in the drive into the side of your television and turning it on. See your manual for slightly better instructions.

The screen on my 1 year old 42 inch Akai plasma tv suddenly went blank although I still have sound. Any clues?


Reset the cable/sat box and tv by turning them off, unplugging them both from the wall outlet, and replugging them after 30 seconds. See if you get pictue back when they get the correct handshake. also, make sure that there are no loose cables going into the TV or into the cable/sat box. You can try using a different type of connecting cord from the cable/sat box to the tv to make sure it is not a bad connecting cord.

What type of cable is connecting your cable/sat box to the TV? Is it HDMI?

Are you using a video game system on the plasma?

Toshiba 42H82 RPTV: Sound but no picture


It sounds like the 200v supply to the crt's is missing. this is the source for driving the tubes, other than the high voltage generated by the flyback transformer. If the set got really bright gray with wome white lines that are kinda on a diagonal, this is generally the cause. the source for this voltage is a diode on the secondary of the flyback transformer.
