Brightness adjustment wont work. When trying to adjust the screen to get a brighter picture it stays the same, can barely see night scences on the tv

There are several brightness adjustments on this TV. Download the manual from the following link. Set the size to a readable %. Then click "Edit", then "Find", and type "bright", then click "Next" repeatedly to review all your brightness options. http://www.manualslib.com/manual/82813/Jvc-Lt-32e488.html#product-LT-37E488

Your set is probable defective

The has a light sensor on the front trying to adjust brightness when brightness or light changes in the room.

Look in the owner manual to see if it can be switched off.

Go to your TV MENU (you can find the button on the remote or on the TV itself)
Go to PICTURE SETTINGS- here you will find color settings and brightness settings
Go to COLOR SETTINGS and just adjust the bars until the picture on the screen is the right color.
Go back and click on BRIGHTNESS- here you can adjust the bar to make it brighter and easier to see your picture.
Save your settings and exit the tv menu.

yes! those are the screen and focus adjustments. 3 for screen, 3 for focus. try this. go in menu....turn down color, brightness, contrast all they way down. you should then have no picture, but in your case a little red. then go to back of tv and turn those 3 screen adjustments all the way down. slowly turn the screens back up until you get barely a picture. because remember, your brightness and contrast is all the way down. the picture should be dim but seeable and with red, green, blue adjustments, make it a black and white picture. when balanced..... turn up color , brightness, contrast in menu. enjoy!

try to adjust the screen at the back of the plyback.a big parts inside the tv with a wire attach to the picture tube. thre's a two knob there, the lower knob try to adjust it

Hi Angel,
Are you really sure , your set has video? How dark is it ? As if really nothing visible? Am, sure you can hear sounds. You can adjust the brightness + button to increase the brightness. But if nothing happens , you have problem with your TV set. The problem might be in the Video section. Please let an expert technician to check it. Please don't do it by yourself, it's risky.
Please send feedback whatever comes up. So we can help you further in the future.

Thanks,

Hi Dawn,
The TV does have a screen control on each of the picture tubes ( there are 3 ) although I do suggest you have a qualified technician make the necessary adjustments as an improper adjustment can cause damage to the set. Should you deside to make these adjustments yourself, you'll need to remove the back ( or front in some sets) ( PRE-CAUTION, UNPLUG THE SET FROM THE WALL BEFORE PREFORMING ANY ADJUSTMENTS INSIDE THE SET ) The screen adjustments are located either on the bottom of each tube or in a group component located where the main High Voltage Wire ( large red wire from the black transformer on the deflection board ) is connected to. Look for a turn pot ( screw type adjustment ) that is marked SCREEN. When you locate it ( whether it be on each tube or in the group component ) turn it up only slightly and not to much, as excessive gain ( turning it up to much ) may cause the TV to shut down. When you have the proper brightness ( when it looks good to you ) close the set up and enjoy the renewed picture. Good luck and I do hope this has helped in some way
