Scrambled screen Turn on computer and the screen is scrambled/ snowy

Scrambled is a subjective term that is useless in trouble shooting.
Sounds like a virus.

DEPENDS ON WHICH BOARD THAT NEEDS REPLACING. Look on Shopjimmy.com they list boards and parts. If you know how to solder I would first resolder boards and check for Bad Capaciotrs they will be puffed up on Top.

Likely another board is bad--GET IT IN FOR REPAIR UNDER WARRANTY BEFORE NO WARRANTY SITUATION

I have a similar problem:

I have a Compaq Presario SR2010NX desktop computer. Recently, very occasionally, the computer would freeze and the screen would scramble. It almost looks like someone chopped up the picture on the screen. Then we would have to manually shut down the computer and restart. It would always work fine afterwards.

Yesterday the computer did it again. It restarted fine but when my boyfriend tried to install a new mouse the computer froze again and the screen went scrambled. Well this time it did not start back up. I tried to unplug the computer from the wall and restart but that got me to the COMPAQ screen and then the computer froze again and the word compaq was doubled all the way down the screen. We continued to try to start it in PC recovery but it would get the the program and freeze. I actually got it to run once but I couldn't see what it was doing because the screen was scrambled.

Now we have restarted it so many times that it will start up, light turns green, and stays green. The computer sounds like its starting up and it seems louder than normal. The computer doesn't do anything and the screen is black. The lights on the keyboard do not turn on but the light in the mouse does. The CD drive will light up and run as well but nothing happens after that. I can't see the cursor and the keyboard does not work.

I opened the computer up, cleaned the dust off, tried to re-install my old RAM and that did not work either. I disconnected the CD drive but that did not work. Tried to start the computer with nothing plugged in except mouse, keyboard and monitor and that did not work.
I don't know what to do! Help!

Test the camera by taking a picture and saving to the memory card. Then download it from the card to the computer and view it. If it is clear, the problem is in the playback system or the LCD.

maybe overheating graphics card, check the fan is actually turning on, usually you can hear it whirring around.

Snowy screen, unresponsive to remote control... Sounds like an interference from something. An example... A hairdryer can mess up a CRT really bad. Anything that is likely to create small EMPs will surely mess up your TV and even interfere with the infra-red. Not marking this as a solution, check everything and test the TV. Here's the test: Turn everything off, except for the TV. If it's still doing it then the remote infra-red is just a coincidental failure with the snowy screen. Sorry I can't help you further.

check eye settting or its a fungus inside lens black screen is due to virus

Normal 0 The Mitsubishi WD-52525 has a serious capacitor problem as discussed in this forum overseen by a Mitsubishi certified repair technician: http://www.hometheatershack.com/forums/mitsubishi/11703-problem-mitsubishi-wd-52525-scrambled-picture-no-picture-2.html. There has been a worldwide problem in computers and TVs over thepast several years with faulty electrolytic capacitors (from Taiwan) thatdecay, dry out, swell and die. The power supply is often the firstcomponent to go bad, but other systems also degrade over time. As theforum explains , this problem is widespread in these sets causing multipletypes of display problems after several years of use. On my set, I also got a blue screen with a lighter blue ball in the middle. Mitsubishi is awareof the problem and will cover most of the cost of repairing the chassis, evenyears out of warranty, but apparently ONLY if you get an estimate from aMitsubishi certified repair station and contact their customer support BEFOREdoing any work on the set. I just followed the recommended procedure onthat forum and Mitsubishi is covering half the cost of my $700+ repair when my3+ year-old set recently died and showed only this blue screen on all inputs.
