Good day.
its not a problem with the screen but with the internal parts. It could be a cause of a malfunctioning parts along the horizontal section. Capacitors are ussualy the culprit. Have it checked by a technician.

I accidentally cleaned my samsung led monitor with windex. there are streaks all over the monitor. i used a soft cloth to try and clean off the streaks and it did not work. Is there anything I can do to...

Hello mrm552,
The best possible case is to use to a proper tv screen cleaner, ex. monster screen cleaner. The solution comes with a cloth. Spray the cloth with the solution first with one or two sprays. Then in a circular motion wipe the screen. You can get this solution at most electronic stores where they sell TV's. Hope this helps, good luck.

I have a shadow on the screen in the bottom right hand corner what could the problem possibly be.

It sounds like something has fallen or crawled into your tv. Unplug unit and remove the panel on the rear bottom. Now remove the upper part of the rear cabinet if you cannot see the problem. You will probably find something on the lense blocking the light. This would be a good time to clean the lenses. Using a soft cloth and windex, spray the cloth then gently clean each lense using a circular motion. Do not wipe until dry as you may scratch the lense. Do not spray the lense as you will cover critical components with corrosive cleaner. Do not push hard or disturb any lense adjustments. Reassemble unit and your tv should look as good as new. Let me know how this works out. .

Tearing Blue streak from top left.

The convergence amplifier responsible for blue is dying. Soon blue will be off all over the screen when it fails completely. Only solution is to have the convergence output IC's replaced.

Streaking inside of screen

Philips screens tend to be very tough to remove as if you are not careful on removal of the screen frame bolts then the whole screen will come falling off.
