Question about ViewSonic PJ755D Multimedia Projector

1 Answer

Image flickers I just replaced what I thought was a bad bulb because the image flickered. New bulb, same problem. I dusted the unit because I understand dust will sometimes cause issues. Also, the unit makes a slight popping sound on occasion. Any recommendations? I am having a difficult time getting an answer from Viewsonic.

It sounds like the socket that the bulb goes into has an intermittant connection problem, or where the wires attach from the bulb socket to a plug or printed circuit board connection, or possibly a bad connection in the bulb driver circuit. Good Luck.

TV wont turn on after dusting


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.

Projector picture flickering


Dusting is not going to help. I could be the lamp if it happens with no input hooked up.

firdt off, did you reset the lamp counter? did you clean the dust out of the projector? it may be overheating as well. if the lamp looks ok, you may have just blown the ballast. try projector doctor online.

Picture flickers on Sony HDTV


Hi,It seems your ballast(board that powers light bulb) is going weak.The ballast was used to provide a lower voltage because lamp didn't use as much as brand new one. A newer one takes more voltage and when ballast doesn't provide as much power it will flicker or produce a dimmer image.I found the one for your tv here: http://www.discount-merchant.com/1091041-KDS-60A3000-p/1091041.htm?Click=48173 Good luck and God bless you!

Boot up problem


It is dust built up inside on the fan wheels. You wouldn't believe it but it is just dust. If you are mechanically and electrically inclined, take apart the housing and blow out the entire unit with compressed air especially all the vents and blower fans (my Optoma has 3). It'll work like new again. I was completely amazed.

Proector image is dim


I have changed the bulb on my LG projector recently. I found the rotating colour wheel to be full of dust. Upon opening the cavity where the light is redirected and reflected onto the imager, I saw all mirrors also had a layer of dust. I don't think it was so dirty that it affected the brightness of the image, but I cleaned it anyway using an earbud. I cleaned both sides of the color wheel as well. You need to be careful in working with the optics of the projector!
