    Sorry for this crazy question, but where do I check the voltage at on my LCD? Do I need to take the back off to check this?

If the audio still working, It means the standby voltages are not working properly on this LCD. There are not many service parts available anymore, so the only way to get the LCD working again will be to replace the defective parts.
If you require more assistance, let me know.

    Is the 5 volts DC that power up the microprocessor, if this voltage drops below 4; the LCD will behave erratically up to the point of not turning ON anymore.

  • Jaime Hernandez Jun 17, 2008

    To measure these voltages you will need to remove the back cover to get access to the power supply.

    I would suggest to be careful when doing this because of the high voltage surrounding the power supply circuitry. If you're uncertain on how to do it, I could repair your power supply, write to jah2mil@hotmail.com for more info.

Protron 32 in pltv3250 will not come on


Does it have a YHI power adapter or an internal power supply? The YHI type has a power adapter box with a low voltage cable that plugs into the TV. The internal power supply TV only has a power cord. dave@thola.com
