Toshiba Satellite screen has a "dark shadow" on the right side.


That could be a backlight or GPU issue. Plug an external screen into the vga out to check the GPU.

JVC DLA-RS1U Projector turns off


I have a similar problem. JVC Project (DLA-RS1) shuts off after about 30 min to 1 hour of use. Everything turns off - bulb, fan, even the little light on the projector near the buttons. After 10-15 min the red light comes back on and you can start the projector.

I have seen this happen when I had installed a knock-off bulb. I believe the bulb runs a little hotter and the projector over heats. Now I am seeing it happen even with a JVC bulb.

I am in the process of taking the cover off the projector to see if anything is blocking the air flow (like a piece of broken bulb, which did break a while back). If a problem doesn't show up there I am going to check the fan to see if it is turning at full speed (maybe replace with a beefier fan?).

Does anyone have instruction on dis-assembly?

I have a JVC tv only 1 year old and the picture is getting dark.


Sorry to tell you but JVC is a well-known un-reliable brand and if it's cheap, probably even worse. U may have screen burn from leaving a games console on while plugged into the tv, even if its not showing the game, it will burn it onto the screen. :(

My JVC 56G787 is dark and bright is turned all the way up


You need a professional.
Stop using the TV until it is repaired.
Continue to use it and your problems will multiply and grow more expensive.
Call the manufacturer to find you nearest authorized service center.
