Have a dark blotch on bottom right of screen. What is this? Transported in the rain and fear water got through carefully wrapped plastic. Help


It's possible the mirror has dome dust on it from jostling during the move. W dried water spot will do it too. The front screen will come off by removing the screws on the bezel. Be extremely careful cleaning the mirror.Any scratch by a cleaning cloth (never use paper) will permanently ruin it.

Red wavy red line on top of picture.faces distorted, but bottom part of picture ok


sounds like you have an output power supply going bad.

the tv is crt projection...which is to say due to its age and technology it will probably be cheaper to just get a new tv.

Sometimes these older style sets end up with compenent board solder breaks that can be spotted visually and fixed by a talented repairman.

My friend had this done to a similar 55 inch set he has about 3 years ago....he just won't give his up either!

good luck and be careful! There is lots of high voltage inside that tv!

Akai DLP projection TV. Picture is fine except lamp is not illuminating a 3-4in area on the left side of the screen. You can see the picture over there but it is dimly lit. I can't seem to find a way to...


The problem is the light tunnel is collapsing. This is a VERY common issue with the Samsung/Akai DLP TV's. It is four mirrors used to transfer the light after it passes the color wheel to the DMD board. When part of it collapses the grey bar that you are seeing is the end result. This is a part that usually requires a technician to replace as there is a little tear down of the light engine itself and you would be handling delicate parts. The part number for the tunnel assembly is BP96-01961A and I have included a link so you can purchase it through the Samsung website. Please take a few moments to rate my answer. Thanks..

How to get to mirror and lenses on a pioneer SD-643HD5?


unplug tv. Remove 4 screws from bottom of tv in front right below speakers on right and left side. Bottom panel slides up and out. Don't disconnect just rest panel on front of tv. Remove two screw at bottom of trim strips on each side of screen. Each one of these strips will slide down and remove. Last piece to remove is trim strip at top of screen. There are no screws to remove. The whole piece simply slides to the right about 2" to 3" inches then will unlock from mount brackets. Pull towards you and slide up and off screen. carefully lift screen up and out of bottom brackett. Top trim piece may be a little tight. Just tap on it with the palm of your hand and have somone pull on strip from other side.
