Question about JVC AV-48WP30 48" Rear Projection Television

1 Answer

Night or dark scenes are too black

The problem I am having is that the night scenes in TV shows are so black that they actually look almost like a negative in a film. It is digital cable with no HDTV and setting the brightness or any other setting to compensate does not help. The TV is about 3 yrs old but it I have had this "problem" from the beginning.

    the solution above is incorrect. This is a fairly simple fix. take the front cover off, remove the black cover with the screws, loosen the crt socket board screws, ane gently remove crt driver boards and re-insert them back and forth a couple of times. then make sure they are on firmly and re-tighten screws. Your set is fixed. re-install front covers. manually re-align set and your ready to relax.

The picture is very dark


Unfortunately, there is no easy fix for this. If it were a rear projection TV, I'd suggest a new bulb. Even on a Plasma there are things that can be done. But on a CRT, the repair for a dark screen usually costs more than replacing it.

I have a vizio Vt470m....the picture has always been perfect. All of a sudden when picture shows scenes with very little light (dark scenes like at night, space, low light) the black color almost look


Either the TCON board or the LCD panel has failed. Start by replacing the TCON board. If the problem persists, the panel is bad and the cost to replace it would be too high.

Night seens are very dark


Call a good TV Tech and have him check all crt anodes for proper connection. Also remove & reinstall all crt boards, clean spark gaps. This TV is also known for having bad convergence amp IC's.

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. :(

How to increase brightness in Canon Powersot A620 ?


Are you asking about brightness as viewed on the LCD, or are you asking about increasing brightness on the actual image taken? If it's the image, there are two special modes that you can select on your mode dial. They are "Night Scene", "Night Snaphot", and "Indoor". A description of both, along with your camera's other special settings, may be found here:

http://www.canon.co.jp/imaging/mode/camera/scene-e.html

"Night Scene" can be selected directly from the dial. It's the one showing a person standing under a star. Note that Night Scene should be used with a tripod to reduce the potential for blurriness.

"Night Snapshot" works almost as well, but does not require a tripod. It can be accessed by selecting SCN on the dial, and then pressing right or left with the selection buttons until it shows in the menu. The camera will remember this setting the next time you select SCN. I usually keep my camera always set to this setting so that I merely have to select SCN to use it.

"Indoor" works very well in those large rooms that may produce dark backgrounds when taking photos. It also does not require a tripod. It's accessed the same way as "Night Snapshot" (Select SCN, then right/left until selected). This is another good setting that I like to keep sometimes set in SCN.

Try all three settings, (and don't forget all the others too). Think you'll be impressed.
