Hi, well I have seen this similar type of thing in my shop from time to time, whenever a screen is bright white, this usually indicates that the screen is being overdriven in the Brightness area, and it is being made so bright as to white out any images, or variations of similar things.
Now unfortunately there are quite a few things that will cause a symptom such as this, from a faulty supply rail from the PSU, to a broken down Diode in the brightness circuit, or even the display module itself.
To isolate and try to find out exactly what is wrong,one would have to have a service manual, & special equipment, and at the least. to my mind these days it's not that practicable to DIY these sets these days, unless it is a clear cut fault and fix, which this is not. Accordingly it is my recommendation, that you contact an RCA local or head office, and ask for a referral to an authorised service center, at the service center first ask for a "Quote" for the repair, before allowing any repair work to be started.
This way you can then make an informed decision as to repair or replace,as often these days we find, that the cost of repairs can quickly escalate,and often it is better to put any monies that would have been spent on repairs towards a NEW, unit with a full warranty.

I am sorry to say but this will be a hardware fix. Your video board has failed and will need to be replaces, as well as the main power board may need to be replaced. Here is a short list on google of the parts you can get yourself. You will need the powersupply and main board. But I do recommend having it professionally worked on if you do not know how to repair this yourself.

Try to manually make it so that it is set to outdoor settings. Or maybe try low brightness and no flash.

Go to your menus, set all to factory settings or default.
Test the camera by using more of the settings, and notice how it works.
The LCD settings especially are what you want to make sure are set right...not too bright, and of course not too dim either.

The screen won't light up and when the screen slided up the screen display becomes too bright (white) that nothing can be read off it


My MDA loses its settings frequently as well. Go to Start, Settings, System, Backlight, and see what it looks like. Maybe the settings have changed.

Your first step in troubleshooting this problem is to plug in another monitor to your computer. If you are having the same problem it is related to your computer. If the second monitor works fine then your original monitor is shot.
