check first the connection lead between pc and pj
to make sure pj is seeing all signal pins on sub d lead.

check the wireing in the new bulb . My new one had the wires in the wrong holes like if there are 4 slots in the connector then my orignal was in slots 1 and 4 the new one was in slots 1 and 3 so I took the wire out and put it in the #4 slot and put it in and unpluged the machine and did a reset and restart and it came on green. Hope this helps.

SOURCE: I replaced the bulb in my projector and now it

You need to hold the help button on the remote control for ten seconds, that should reset the lamp hour. NEC decided to make it inoperable after 2100 hours on the bulb.

Red line across the top of the screen. bulb was just replaced


HELLO,

IF YOU HAVE A SOLID RED LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER


I HOPE THIS WILL HELP OUT IN RECTIFYING THE FAULT AND DO TAKE CARE IN SOLVING THE PROBLEM , BECAUSE THE TELEVISION CONTAINS HIGH VOLTAGE....

Purple blotches


Ok, so I'm about to flip a lid with my TV. I am showing purple quater sized blotches all over my screen. I bought it for a discounted price because of this issue, in hopes i could fix it. I took the back panel off the TV. ( about a 6in * 6 in plate) removed the light bulb and cleaned the bulb and lens, where the light bulb faced. I used a dust cleaner and special cloth. NOTHING! I took the entire front screen off cleaned it and then cleaned the mirror and second lens.... NOTHING! Then i heard that dusk sometimes gathers behind the lens and that should be cleaned. Try this, Its 4 screws, just be careful and remember the way you took it out, because it has to be replaced the same way.

Thick color lines on screen


Hi ,Sorry, this is not a solution. I have a question about your line. Is it transparent? (can you see through if the picture is bright)Does it remain there all the time if you change inputs? My LG 42" just had a blue transparent line appear on the right side of screen. Tried a few trouble shooting things w/ no change. About 1 hour later it went away. Did you find a solution and what was it?

Projector Colour Problem


Could be a few things....first you need to isolate a signal source issue or a faulty LED lamp. Simply unplug your signal source and run the menus on the projector. Purple Gone with source unplugged = faulty source our signal Purple still there = faulty device Sounds crazy but make sure you have no interference devices running real close within say 2 feet. cell phone, microwave, magnets, high voltage eletricity...etc
