I am having a problem with my Samsung HLN4365W DLP Television. There are 10 vertical grey lines spaced about 3 inches apart running across the screen. Furthermore, the whole screen appears to be broken up by vertical lines. Any Advice??

Hello,

Thanks for contacting Fixya.

Have you removed the back of the set and cleaned the fans every 6 months. It is a projector that depends on two computer fans to keep the lamp and the DMD control module within proper temperature limits. If those fans get dirty and slow down or stop, bad things happen. All it takes is a screwdriver and the brushy atttachment to your vac hose.

Now this happend, because a bad soldering connections in that module. Lines will come on and off. Probably 1 day will stay on. For last 2-3 years im seen that only on hlm and hln series. Probably
happens on other models. but, i never seen that. Is not that hard to replace that module. You have to remove 2 screws from left side and 1 screw from bottom righ side of module and 4 of them
from around dlp unit unpulag all cables ( i think 3 cables ) that it. Same way install new one in.
but you will need to adjust a module position to get picture to fill whole screen.

God Bless

I have a 43 inch samsung DLP tv 2004 model# HLN4365W, I was getting a black and white picture, so i replaced the color wheel which was broken. It worked fine for a couple of days then there was no picture,...


No picture on a DLP when you can see the lamp is working is ALWAYS the DLP chip. BECAUSE you recently replaced the color wheel, i suspect that the LVDS/data cable to the light engine was not plugged in well and has come loose. I suggest checking and rechecking every cable and plug you can find.

White lines equally spaced 1" apart.


This is probably caused by the small signal board. It controls and decodes the picture information before it is sent to the display panel. It can be fixed by a quailified technician and if you contact philips (this is who makes magnavox) they will tell you the closest certified technician. Hope this helps.
