Question about Sanyo DP42848 LCD TV
When I turn it on and the green power light comes on, the screen stays blank. I have tried to change the channel and the inputs, but still nothing. Even tried it with nothing hooked up and the screen stays blank.

Hi there! The panel may be in protection mode. The Inverter board is the most logical area to start after checking power supply Voltages.(5,6,24 and 13Volts). There may be coils on the Inverter Board which have bad soldering or faulty. Other than this it may be main board which controls switch on or off. If all else fails, refer to a repairer. Beware of High Current!!! Best Wishes and Good Luck, Jus004

You may have a defective inverter. The inverter provides the back lighting you need to see video. There is good chance the starting resistors have changed values. It would be best to replace the inverter in your case. I would have to have a schematic to find the bad resistors. Thanks for asking and show a few hands of support.

power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
Hoping that this will help out in solving the problem
