Epson tw3500 purple line + start up issues

Epson tw3500 came up with a thick purple line that run across the bottom of the screen. This first occurred when the projector bulb was changed for the first time, the bulb was changed once more but the problem remained. After a while the projector stopped turning on after first attempt but that has escalated to only turning on after about 10 attempts.

SOURCE: images has a blue color across the center

Wow, 3 in a row. As described on 2 other projector issues this is very similar to those others. I'll repeat the info here.

I assume this is an LCD. I don't remember the s4 being a DLP projector.

This sounds like the LCD panel used for the blue color has gone out. The image is made up of red, green and blue images layered upon the screen. If the blue panel has gone out then there is nothing filtering out the red light in the image.

It looks like yours has just a secone of the panel dying or comming loose from it's connector.

It could be a simple open and reconnect fix. I personally have never opened a projector, so I'm not going to walk you through it as I do not know how hard it would be to tinker with. It should eb a cheap fix for a true repair man though.

SOURCE: When connected to any computer and attempt to play any video,it has a bunch of horizontal lines resembling a barcode running horizontally across image.

Hi my name is Vortash the bars you are seeing are the result of a capacitor or diode failure in the projector possibly in the power supply , they are usually referred to as ac hum bars .. this is where a circuit that should be running on pure dc voltage is being tainted by ac seepage from another part of the machine .. its also possible with the heat generated in these units it is just bad solder or dry joints ,,, best get an engineer to check it though as ot may damage the bulb and I would bet money on a repair being cheaper than a replacement bulb hoe this helps regards Vortash

42 inch samsung plasma tv black vertical lines


Hi, Depeending on the thickness of the lines matters. If the lines are Black and about 1-2 inches thick it may be a bad bottom buffer board or a bad panel (screen).
If the lines are thin 1/16 to 1/8 inch it is most likely a bad panel.
You can open up the set and depending on the model, see the thin board/boards running across the bottom with ribbon cables going to the panel. You may be able to attempt reseating the ribbon cables, but be careful as some retainer plugs break very easy.
If the lines are thick black and the reseating doesn't correct it you may be able to buy the coresponding buffer. Unfortunately some bottom buffers are actually part of the panel. If you are not comfortable taking it apart then call a professional but be aware labor charges start around $200 not counting parts, panels start at $600 up to over $1000
hope this helps
Thanks
Eric
