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.

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. :(

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.

Static 'white' sound


Good day.
Try to remove the cover of your unit and clean the tube with a dry cloth. try to look for the anode cap. the one tht is connected to your tube if there are holes in it. This causes the problem.

response is highly appreciated,

Brightness of picture


If you feel good about opening your set then you can try this: Look for the flyback (high voltage) transformer, with the thick red wire which goes to the top of the picture tube. There are 2 controls on the flyback transformer, focus (top) and screen (bottom)Turn the brightness and contrast all the way down and then increase the screen control until you see retrace lines, and then back it down until those lines just vanish. Return the brightness and contrast to normal and adjust the focus control, if necessary, for a nice sharp picture. Let me know if that brings your brightness back.

Picture adjustment questions


*The brightness control setting determines how bright your picture will be. *The contrast control sets the gain of the video circuit. This determines the difference between dark and light scenes. Low contrast settings make the picture "hazy". High contrast settings make the picture more distinction between dark and light scenes. *The sharpness control determine the frequency response of the video circiut. High sharpness settings give better resolution but also shows more noise in your picture. Lower sharpness settings smoothe out the picture removing noise but also fine detail. It needs to be set for the best all around picture. *Picture Enhancement is pre-set adjustments which give you different picture qualities. You just select the one you like. Stargazer
