Question about NEC MultiSync LCD4010 40 in. Television

1 Answer

No display I just got a used NEC Multisync LCD4010. Im trying to hook it up to my computer using the digital harness but nothing comes up. The screen shows a kind of grey/blue tint and does nothing. When I unhook the harness from the screen, a red led comes on next to the green power led, and when i plug it back in the red one goes off, and the tint returns but no picture. Ideas?

When you get the red and green leds lit it means the screen doesn't see an input signal and has gone to stand-by. That the red led goes off when you reconnect suggests a signal has been recognised by the screen but be very aware that it may not be a good signal. As you are using a PC input I will assume the signal is RGBHV, maybe you have the H and V swapped around? I would try another computer source into the screen.
You say you are using the digital harness, please explain exactly what this is.

My NEC MultiSync Lcd4010 turns on, briefly showing input info in the top right corner. Then the red light flashes 3 times and the process starts again. No picture comes on,just the info.


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. Viewing it in "Mosaic" or "Magazine" will make surf easy.

Umada mod lwd400-s1


a matter of broken electric electric capacitors inside your TV.

Solution:
- Open backplate (loads 'o screws and ruins your warranty)
- Remove the connectors from the center circuit board
- Remove the circuit board via 4 screws located on the side
- Remove plastic on the back of center circuit board
- Remove cooling plates of circuit board
- Look for bulging capacitors
- Solder these out
- Go to local radio shack, take the capacitors (and spend about 5$)
- Resolder new capacitors
- reinstall circuit board
- Hook everything up and close the back plate

Voila! (at least, this worked for me)
