I have researched this problem and it is so common we that own this piece of junk ought to form a class action suit and sue. It is caused by a bad part or bad connections to a part called a backlight inverter. It seems the LCD needs a higher voltage than supplied by the 12vdc power pack so this part re-chops the DC voltage to generate the LCD requirement.

The date of manufacture is on the back of these TVs and all the problems seem to be from those made in 2006 to 2008

SOURCE: My Sanyo DP46848 LCD TV display goes black when turned on.

My mother's was doing the same thing (purchased 2008). Put up with it about 6 months and took it to a repair shop. Bottom line - the display panel has a flaw in and will cost more to replace than the tv cost. See about it now it yours is still under warranty.

The first thing I would do, is find a buddy with another power supply and see if it was not the system. If your system is still under warenty, they will fix it for free. The power supply is way cheaper to purchase than a whole system, so you really need to make sure you're not needlessly buying things.

On the back of this power supply, Theres a red switch with the numbers, 115 and 230. depending on which way it was switched on. Can someone please explain to me what this is?

Hi inforis,
That is a setting that will change the voltages, and you do not want to flip that switch. If you do there is a chance you will fry your computer. Different countries use different voltages. It's cheaper to make a switch & some circuits inside the PSU than make a whole new one. List of countries with frequency & voltage (
Hope that answers you question well enough.

The on/off switch is not working. The only way to turn it on and off is to unplug and plug it back in.

Hello sir/ma'am, hi! here are my likely solution to your problem:
Let start with the easy one: 1. the power supply switch, you may need to feel the switch, like a click or a snap when you press the power button, if this feeling is not present on your switch, this may need replacement. OR
the serious one: 1. You may need a replacement power supply board. the thing is we don't usually replace the bad component, but the whole board, due to modular construction. so if the power supply board is the problem this goes out and put in we then put in a new one.
The defective board goes back to service and testing, if given back to the manufacturer, this takes a lot of process.

What will happen to the hard drive in power failure?

Power failure as in whole house power failure? Or the computer's power supply failure?
Whole house failure, nothing, the computer will shut off and require rebooting, at which time you may receive a message the computer was not properly shut down, just continue as normal.
Computer power supply failure, same thing, nothing, except the computer will not reboot as the power supply has failed.

Watching television and lost all power. tv is pluged in and still no red stand by light.

You power supply board is bad. This was most likely caused by a power surge.

I would change the whole power supply to fix the issue but you could also try replace any bubbled capicators for a cheap fix.

The capicators will be less expensive but many times you will have the same issue once again if there is extensive damage to the power supply so the best thing to do is just replace the whole power supply board.

7945g can't use power supply of 7940

You'll need to buy a another power supply unless you have power over Ethernet. The power supply for 7940G/7960G is CP-PWR-CUBE and for 7941G/7945G you'll need a CP-PWR-CUBE-3. Yes, I know, I just got one of those and it's a pain to configure it, but I got it working... ;-)

P.S. If you haven't notice, you will be dealing with a whole different thing, the configuration/settings will ALL (except for the dialplan file) different from the 7940G... Good Luck ;-)
