Shine a flash light on the screen up close when the TV is on. If you can see anything at all the board that controls the white light isn't working. If you see nothing then the board that controls the picture is bad. This board has one or more flat ribbon cables running to the bottom of the screen.

Testimonial: "Thanks for the assist Lawrence. I feel that it would probably be cheaper to replace the TV than to try to repair it."

    Oh, don't give up so easily. I spent 36 dollars to replace a bad screen controller board on my Sharp aquous TV. Took 1/2 hour to make the TV operational

Model: LC-70LE732U Problem: No audio or video. Error code: flashes 1 long, 1 short Tried: Reset to Service Mode: Replug W/ holding Input + volume down Response: solid light for 10 sec, returns to...

According to the information I have on error codes for that set this is a back light issue. Try removing the plugs to the back lights then plug the set in and see if you have normal voltage, if you don't it may be a power supply issue but I think your going to find the voltage is normal with the plugs unhooked and they drop off if they are hooked up, meaning you have at least one bad back light strop

The yellow light comes on inside but the computer won't come on neither does it beep?

First remove any power cables and batteries(if laptop) from your system and hold down the power button for 15 seconds.

Plug the power cable back in & attempt to boot.
If this does not solve your problem then you will need to remove all non-essentials from your system.

If laptop, this simply consist of battery, ram, optical drive & any other removable bays or devices. Unplug all cables except the power cable & attempt to boot.

If desktop, you will need to remove any cables plugged into your computer except keyboard, mouse, power, video, sound, & network cable. Open the case & remove any PCI cards, except video cards, unless you have on-board video, unplug the data & power cables going to the optical & hard drives. Now attempt to boot. If you have no luck you can remove your RAM sticks & try again. If you get an error beep warning you about no ram then you might have a bad ram stick. If none of the above works then you may have a bad power supply or motherboard. Power supplies are pretty easy to test with tester or use a spare.

My new gaggia accademia won't work. It shows error code 19. Can you help me?

Hi, Error 19 is not known by me. Sounds like something is not resetting or has failed. Try turning off the machine at the main power switch and unplug it from the wall for a few minuites. Remove the dreggs draw and drain tray and replace them before you plug it back in. This will allow the machine to reset. Dazza REPAIRER

My Sony Music system DVX MP3 is not getting on when the power button on the music system/remote is pressed. The red light is blinking. Please let me know what is the problem?

Possible that the output is short as the protect is shutting off the system.
remove off the speakers and try once again.. If not remove plug and keep aside to reset or try to depress menu/select while power plug is put into.
If the fault satys you will have to disconnect the output, power to sub circuits and check if the set triggers.
Make sure the mP IC gets voltage and reads remote signals.

Hit power button and nothing other than lights flicker once

Remove everything from the board except the front panel hookups.Make sure you remove memory, video card, hard drive and cdrom cables, hard drive and cdrom power, anything plugged into the back except the power. If it will power up this way start plugging things back in between power cycles. Start with memory then power down. Then add video then power down. Continue with Cdrom, then hard drives. When it stopps wanting to power on you know where the issue lies. If it wont power on with nothing on it then the motherboard is probably bad. Hope this helps.

No display

Try swaping your memory with a known good stick of ram.
Are you sure your monitor is good? Video cables?
Try changing (if pci) slots when installing video card.
Other than these 3 things the only pretty sure thing is; sorry, mother board or cpu.
