SOURCE: screen went black on my 42" sanyo model dp42647 lcd

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

Try disconnecting the connector KBL on the main board as shown in my picture #DSCF0585 to see if the backlights will come on, if it does, the main board is bad.
Also check the voltages on the output connectors of the power supply.

Why does my sanyo dp46848 screen go dark but whites are too bright?


First try to gently push the cable between the main board and the LCD controller (T-CON) board and if that doesn't affect the image then replace the T-con board.

No picture there used to be lines at the top


It sounds that there is some loose contacts with any cable connectors, or to any solder terminals at the circuit board. It will be best to contact any service technician, or the authorized service center for Sanyo. Gopakumar Gopalan Google

Sanyo DP46848 im stumped lol... with nothing connected ( aka ) cable and or any other components .. just plug and turn on .. the screen has a solid blue bar from top to bottom with small white lines in...


Although you have not posted a picture, I believe you may have a screen or LCD panel problem, the panels have film connections that go from the t-con module, through the panel control pc boards then through thinn film connectors from the lcd screen. Likely this is the problem.

I have the sanyo dp46848 it 3 months past warranty , we had a thunderstorm ,my wife turned off the tv but we did not unplug it. when the storm was over we turned it on and all we got was a led power light...


It can be the main logic board EPROM is scrambled since the TV was plugged during the thunder storm, and /or the power supply module are damaged.
You will have to do more in-depth troubleshooting.

I have a SANYO DP46848, after i turn on the TV after a few minutes the picture turns a blue/grey color. There is still a picture and sound, but poor picture quaility. Need some help?


The ic on the T-con board is failing you could confirm this by spraying circuit cooler on the ic . The T-con board is located in the middle top on the unit has a cable from the mainboard to the t-Con
and two other going from it to the panel
You can try either Shopjimmy.com or TopsElectronics in Haverhill Ma
