Vertical lines all over image after few minutes turn on

I had this projector for a while and rarely use, lamp life is about 2000 h left to use. Recently after 5 minutes or so of power on, the screen is broken up by many vertical lines ( continously from top to bottom screen )with equally spacing. Picture is still there but degraded badly by these lines ( like mosaic affect ). Colors are ok, sound is ok . Checked connection, cable etc... OK.
Please help me with your expertise. Any suggestions would be verymuch appreciated.
Many thanks

Re: Vertical lines all over image after few minutes turn...

I've got the Proscreen 4600 Endurance. Same probs with vertical blue lines to the left of white. Have tried s-video and composite (single analong) cables. s-video is better. when connecting to computer via data cable image is better yet.otherwise I think it's probably a service job, case seems difficult to open so far.....

Re: Vertical lines all over image after few minutes turn...

Well i think we have the same problem i with our proscreen 4700 and the only thing i found out so far is that the rca and svideo jack on the projector have gone bad. Tried the data connector and the video was perfect. Tested the rca jack with new cables and another dvd player and it was still mesed up. So it is the hardware that controls the input for the rca and s vidoe jacks but still have not found a way to get the case open to see if some thing can be fixed from the inside.

My nec vt48 projector gets hot and turns off. It gives off 3 beeps a few seconds after

This problem and the error beep codes indicate a lamp that needs to be replaced. The correct part number for the lamp is VT85LP. Basically the lamps are rated with a life expectancy of 2000 hours. At the 2001 lamp hour (3001 in eco-mode) the LCD projector will power on, but not display an image, due to the indicator requesting the lamp be replaced and the lamp hours reset (hold the help button on the remote for 10 seconds when powering it on).

Mitsubishi HC900 Projector shuts down after 5 minutes.

You have 1 of 2 possible problems.

(1) You need a new lamp.

(2) You have an overheating problem.

Just a quick couple of notes about your projector. It is a DLP projector (not LCD) and as such the machine as no air filters to clean. It does have air intake and air exhaust grilles, but no air filters to clean. This next part comes directly from the owner' manual for your projector:

When the lamp operation time exceeds 2000 hours*1 *2, the projector automatically shuts off and can’t be used until the lamp is replaced and the lamp operation time is reset.

Your machine is designed to give visual warning messages at 1500 hours used, and 1900 hours used. Did you see any visual warning about lamp life over the past few months?

If you were experiencing an overheating problem, a "TEMPERATURE!!" message would flash up on the screen just before the unit shuts down. If there is no warning, you don't have a heat problem.

If you have a replacement lamp available, install it and reset the lmap hours according to your user manual. If you don't have the manual, google it on the web (it available).

Screen adjustment

Adjust the screen area of the computer’s display settings to match the projector’s native resolution. Refer to your projector documentation for the optimum or native-resolution setting for your projector model. If you can't find this information or are uncertain, most projectors support a maximum of 800 x 600 pixels.
• With certain laptops, you might need to disable the laptop display to obtain the best image, especially when the native resolution of the laptop exceeds the native resolution of the projector.
• Font smoothing will automatically generate a cleaner font outline, both on your laptop and on the projector. To apply font smoothing, do the following:
In Control Panel, open Display.
On the Appearance tab, click the Effects button.
In the Effects dialog box, select the Use the following method to smooth edges of screen fonts check box, and then select Standard or ClearType in the list.

If the projected image is dimmer than it was on the laptop, check your projector documentation for information regarding lamp timers. If the lamp life has expired, replace the lamp for maximum brightness.
If the projected image is not rectangular, try one or both of the following:
• Make sure that the projector is perpendicular to the viewing screen.
• Raise or lower the projector.
If the projected image displays vertical lines, "bleeding," or spots, try one or more of the following:
• Adjust the brightness of the image.
• Check the projector lens to see whether it needs cleaning.
• Adjust the sync and tracking on the projector.

Vertical line

Hi Abouttime

This is unfortunately a sign of Mainbaord damage to any make of Projector.

But do give this a go , you've got nothing to lose.

Try using a different signal cable and then pressing Auto on either the remote of the Projector or the Projector it self once the line appears.

Thanks for using Fixya !
