This is most likely an inverter problem. This is kind of like the ballast in electric light. If you shine a flash light at the screen, can you see a faint image of whats displayed on the screen? If so, you have a bad inverter. You can find them on eBay for around $5. Just type the name of your computer in the search thing followed by the word inverter. Such as "Compaq dv2500 inverter". Once you have the new inverter, remove all screws from around the screen. they are usually under the rubber feet or round stickers. Once the screws are out pull the bezel off from around the screen. There are clips holding it in place, which usually come apart when you kinda twist the bezel. Looking at the bottom of the screen, you will see a long narrow board with a wire sticking out of both ends. THis is the inverter. Is you computer off? I hope so, because you can get a nasty jolt from the right side of that board if its on. From here it should be pretty easy to replace the board. Just remove the screws, pull the wires and put the new one in.

The LCD Memorex model MLT3221 turn off the display with no reason the sound remains work properly


If the screen has gone off but the sound still works then its most likely the inverter has gone bad. Check for open fuses or leaking and expanded capacitors.

I need to replace a broken screen on a sony bravia kdl40ex400. I have worked on a lot of electronics, but never a tv screen replacement. Can i get the parts myself, and if so, is it changable by me?


Yes - just be careful with the ribbon cables. You are going to be replacing the LCD portion - behind it is the backlight assembly. Some may come with the entire assembly in one. You may need to do a little research to get a replacement - use Google to find a distributor.

Hitachi projector problem


Many Hitachi projectors use 3LCD technology which supposedly makes colors more realistic. 3LCD means that the projected light must pass through 3 seperate LCD screens. Each screen has one color but when mixed, they form a nice picture. I would guess that one or more of the LCD screens have gone bad. That is a hardware problem that I would recommend talking to the manufacturer about.

Power supply tv


Only between exact same models. Even then some models have several different versions depending on type of LCD panel used. If you have another power supply from the same model and all the plugs are the same you should be fine.
