Question about Epson EMP-TW1000 LCD Projector

1 Answer

My Epson TW1000 projector recently developed a problem whereby it would start to display red vertical lines over the picture. This began occuring infrequently a few months ago on start up but now is permenently there. It occurs when the projector starts up and when there isn't any video source connected. The lines aren't fixed and will change position and intensity dependant on the colors being displayed from whatever source or menu being displayed. I've been through all the display setting and nothing makes any difference. I have clean out the filters and the projector seems to be getting good air flow.

First, try using other cables you are using from the source, for example, if you are using a laptop or PC and you are using VGA cable, try using another one. This also applies to any other cable such as S-video, or the simple Video In RCA cable.
You may also want to check the plugs or the port connector, specially with the VGA or D-Sub on some models, look for obstruction or bent pins. Loose or obstructed or even corroded terminals and ports contribute to such "streaks" or even worse poor image quality.
Another thing to consider, specially if you are using a PC or Laptop, is to check the setting on the OS,(Graphics Properties). Be sure to set it according to, or as stated, or required resolution depth.
Lastly, if the lines you are referring seems to grow, or multiply as the projector heats up.Or, the lines seems to be "rolling" or "moving"- try one of these simple steps;
-- try other cables -- try locating the "SOURCE" away from the projector, put them separated, away from each other -- if you are using HDMI cable try using a new one -- if you have plugged in the projectors power cord "along" with other electronics, in the same SOCKET, or extension, consider re-locating on of them, if possible, let the projector have it on "solo" -- if your projector's Power Plug being a three prong, try plugging it in a three prong socket, or you can buy a 3-to-2 plug adapter
If none of those mentioned steps the following could be a possible fault;
-- LENS or the projector -- the board or its components, IC'S etc
wherein any of them could be costly, firstly, the availability of parts, specially that being a digital equipment,thus, its quite hard to pinpoint the "real" fault, without actually trying to test with instrument or another replacement part.
But as for my experience on our ACER projector, the Plug relocation just did the trick, somewhat an interference caused by the grounding (improper).And making the projector "solo" on an extension or wall socket.
Hope this helps.

After i replaced the lamp on my epson emp tw700, the red flashing warning indicate something wrong. What can i do to fix this problem?


My tw-700 warning light was flashing red (1sec) and this is what I did to fix it.

Take the top cover of the projector, you will see the PCB on top of everything.
Remove the PCB, be careful when disconnecting the ribbon cables.
Looking from the rear of the projector, you will see a metal bar held on by
2 black screws just in front of the lamp. remove this bar which is holding in a
small plastic door that has glass in the middle.
Remove this plastic door and lubricate the bottom of it with some high temp
grease. now put it all back together and with a bit of luck and if you plugged
everything back in properly, it should work.

This worked for my red light problem anyway, hope it helps you.
