Way too dark screen during night scenes on sharp 32" standard screen

I am contemplating buying a 32" standard screen sharp tv from this guy tomm. morning but he told me that when he watches scenes in movies or tv shows that are shot in the dark they are very dark, you almost can't see them. he said he bought the tv 3 yrs. ago but the problem started happening 6 mos. ago. i called the sharp cust. service line but they couldn't help me without the tv in front of me but they said it could just be stuck on some "ocs mode" but i was wondering if anyone could tell me what the problem may be and whether it would be costly to repair or more likely something i could fix myself. it's not a flat screen or anything special.. just a 32 inch sharp. I'd really appreciate some info.

Patrioticdog-I have just answered a similar problem, you can remove the back and find the flyback transformer. The big part with the round rubber plug hooked to the pix tube. there will be two controls on the flyback one for focus one for screen. turn up the screen ever so slightly,your screen will brighten up.Also if you check the main pcboard ass'y there may be a sub bright control same thing small adjustments. maybe tell the guy to give a bit off cause of repair ,good luck let me know. cooltek Feb15/08

Thanks cooltek......solution worked perfectly. I had the same problem with my sharp (tube t.v.) 32 inch and was about to throw it out until I came across this website and your suggestion. It was a little tricky to get at the buttons but once I did, it brightened up the screen immediately.

Color is grate on my Sharp 26" TV. However night scenes have become almost too dark to see. I have tried to adjust the settings but no improvement. Is this a fixable problem? Using Comcast Cable a


Check 'brightness' and 'contrast' settings in (usually) 'picture' menu. Use a recording (DVD etc.) of a dark scene to adjust the picture. My TV (not Sharp) has several pre-programmed picture settings. If yours has that, maybe one of them will be good. Otherwise, use manual settings.

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.

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. :(

Flicker


I have the same problem when going to dark scenes from a bright scene or during channel changes. Sharp sent a tech under warranty and he installed new software to no avail. He called sharp tech support and they suggested turning on opc. The TV works fine but you must adjust sharpness and contrast to achieve an acceptable picture. I paid $868.00 for the set a Sam's club and will buy an extended warranty. I will not buy another sharp. My 40" sony works perfectly.

Faint blue vertical bars on screen


What you see on your screen are retrace lines, it can happen for various reasons. Jut lower the screen voltage by adjusting the knob specified as "screen" on the LOT, this will disappear.
