Caps inspection first, voltage checking next.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Does this TV have a replacement bulb?


hi Traci.

The online references, manuals, etc, refer to a back light, but then generally start pointing toward the backlight inverter, which is the power hook-up for the light source. They can be found on eBay
toshiba 65 ht 2 backlight inverter . Videos such as this one talk about replacing such a unit in a Toshiba, along with diagnosing what exactly has failed between power and the picture screen that's gone black.

Hope this helps!

Sony KDL42V4100 - No picture (and no menu), sound only?


There could be several things that can cause this. Could be a bad CCFL bulb, inverter, power supply problem, main board, or T-con. You will need to have the set diagnosed to track down the problem.

Engine check light stays on


If the vehicle runs fine it could be your oxygen sensor. Some auto parts stores (like AutoZone) will diagnose the check engine light code free of charge. You could also buy a handheld OBD2 code scanner and diagnose the code yourself. The scanner plugs into a connector under the dashboard.
It's pretty simple to use. A descent scanner will run about $50, and you can use it to diagnose codes on all your vehicle's thereafter.

Sony vaio desktop wont turn on


This type scenario normally indicates a power supply failure. Try connecting a known good power supply to your Sony Vaio desktop.

If you do not have a spare power supply, (many people do not) the alternative is to short the the black and green wire on the power lead connecting to the motherboard using a paper clip. This is not a desirable solution and very dangerous, but will help to diagnose the problem. Do not insert any objects while the power supply is energized. Ensure it is unplugged first.

Should the computer start with the green and black wire shorted, the problem is with the power supply. If not, the problem is likely at the motherboard level.

Hope this helps you.

Black screen


This denotes a power supply issue. I would venture to say that it is the part of the supply that controls the plasma ignitor if this is a plasma TV or if this is an LCD screen it is called the back-light and inverter circuit. The power supply board would be the chief culprit in this case.

I hope this helps,

Thank you,

No Picture on LCD TV


The back lights can burn out, also the power supply capacitors leak and blow out. The bulb(s) are a tough fix, the capacitors are somewhat easier.
