Da-Lite Cosmopolitan Screen stretch marks

did you adjust the valves and are you sure after you put belt on and have it tensioned that you ran the motor around by hand at least 2 full revolutions?

if you do this and then find the marks are off...you either got it wrong to begin with, or the timing belt is stretched...hope you didnt try to reuse the timing belt...anytime ya take one off you should change it

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

take off end of track and manually release the spring.

After pulling the screen down to the desire length, The mechanism will lock itself once you stop pulling.

To retract it, you need to pull the cord down again and allow the screen to retract on its own. The screen will retract rapidly at first but will slow down to a gentle stop when it reaches the case.

Try it.

Assuming your screen a motorised type and is able to move down and up when you press the remote, it means that the motor is working well. 2 possible reason are:-

1), The limiter mechanism to stop the movement for the up and down position is faulty or misalign. Up limiter in this case require check and realignment.

2), The end of the screen ( the bottom ) while closing ( move up ) stopped too late, over shot and it fell down on the other side causing that extra length hanging. Up limiter in this case require check and realignment.

Pls contact your local Dalite support if you are unable to find a repair man.

there is a problem with your convergence circuits which align the red,green,and blue colors this must be serviced again. sorry.

Hi,

Hope you have the correct resolution selected:

HD View Modes: When viewing an HD program you can select the following 4 viewing modes.

• Dot by Dot (1080i/p only): detects the resolution of the signal and displays an image with the same number of pixels on the screen. When a 720p signal is being input, the image will be delivered in full screen.
• Smart Stretch: suitable for stretching 4:3 programs to fill the screen.

Also verify if you have set auto timer to 30 mins or so thats why the TV shuts down after a particular time.

Thanks

take it back and exchange it.

Replace upper screen and the Upper front bezel.
Or replace the upper screen and the complete DS Lite Housing. You can find them on the well known auction sites. Please be aware that you must know what your are doing. If in doubt, send it to Nintendo or a local Nintendo repair service

Hi there

We've had this problem once before and at the end of the whole story the supplier had to do it for us , because they use a machine to do this.
