Toshiba Laptop Boot Error

Model: c655d-S5200
Operating System: Windows 7 Professional

1. This laptop was working fine and started to slow down. The next day the Windows and log on screens were extremely slow. I thought this may be the beginning of a virus.

2. I booted the computer and attempted to log on and start a full virus scan. Then, I received an Error: Check cable connection
Error: PXE-MOF: Exiting Intel PXE-ROM.

3. Windows 7 will not boot-up and there is no prompt for log on. The PXE-ROM error intercedes and continuously...

Re: Sanyo Plasma DP70747 Powers Up No Sound Or Picture

I have tried flicking through audio and video sources but there is no change. Can the boards be tested with a Digital Multimeter to detect any faults? I have a multimeter.

Yes, I can see a slight glow on the screen.
Here are several additional photos with much better lighting....

Re: Sanyo Plasma DP70747 Powers Up No Sound Or Picture

I will upload another group of pictures that are lighter and easier to see tomorrow on Monday Feb 11.

When the TV is switched on (remote or side button) the power button on the front of the TV lights up and it remains green color. The screen powers up normal (flickers on) but no picture shows. The picture screen looks dark grey as if it is waiting for a picture to show up. When I turn the power off, the screen is black. Yes, I have a digital multimeter.

My TV clicked and powered itself off. I turned the TV back on with the remote control. The front panel green light comes on, screen powers up but there is no picture or sound. Apparently, no menu showed up with the remote since there was no picture. I tried the side panel button but there was no difference. Next, I tried researching my options and possible advice on line. I removed the back cover and checked the boards but I did not find any burn spots or leaking capacitors. The sticker labels inside the TV states LG electronics, dated 2007-05. I found four fuses, checked them with a multimeter...
