I have the same TV, and the brightness has been fading for some time, so we have compensated by adjusting the brightness setting up higher and higher. We have the brightness setting now cranked up to 100 (the highest setting) just to make it look almost normal.
The TV is only four and a half years old and gets relatively light use (less than one hour per day). Very disappointing.

Please note: universal remote code lists are usually limited to devices that were programmed 6 months or more before the universal remote was programmed. Since the 36HFX72's manual has a copyright date of 2002, the CT-90121 may not control devices built in late 2002 or later. I hope this helps.
The TV's main culprits to be causing this problem are "dynamic contrast" which maybe darkening the backl light in dark scenes an example a night time or a dark scene in a movie. To make the blacks be deeper (as LCD/LED TV are rubbish at blacks) or brighten it on bright scenes to make the light be lighter and once again to make the blacks be deeper so the images pop out. Also "eco lighting" this will dim or brighten the image based on the amount of light in a room in order to be saving energy. Ether way the easy fix is to turn both of these features off. You will get rid of the problem and enjoy more subtler shades of colour that would otherwise be bleached (brightend) or crushed(darkend) out..
According to Toshiba, the CT-90121 isn't a universal remote control. This remote only works with TOSHIBA TVs with the following model numbers:
32AFX62, 32AFX63, 32HFX72, 34HDX82, 36AFX62, 36AFX63, 36FX72, 36HFX72, 42HDX52, 42HDX82, 50HX70, 57HDX82, 57HL83, 57HLX82, 65HDX82, 65HLX83 Unless you posted the wrong remote model number (?) your Toshiba remote isn't going to work with your RCA TV.

You may have a burnt out blacklight... You can fix it easy by having the tv on while it’s a bright picture than quickly unplugging it... or it would be best to get a new TV.
Can't solve this problem, because I have the same one! I can say that adjusting some of the fine picture contrrols, like brightness, contrast, color etc help a little. This TV is supposed to go 720 and as high as 1080 I thought?..........
you can bring more brightness by removing cover on your tv and then you will see ther 2 button ther in back of your tv one is FoCUs and other is G2 rotate the G2 button till you see more brightness on your screen put the cover back and that is if you dont know to do that go to one authorised service
If this is a CRT-based TV and it's been played most of the time, you may have a bad picture tube, especially if strong red colors bleed to the right. CRT's dim with use, unlike LCD or plasma. But it could also be trouble in the video circuits - none of this falls into the DIY category, unfortunately. High voltage involved, unless you're comfortable around it and want to try turning up the screen controls inside the TV. If you do, let me know - but "no response at all" from the external adjustments points to a more serious problem.
*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.
