One of the drivers in the high voltage section is bad. It is most likely leaky electrolytic capacitors in the driver circuit that need to be replaced this will fix your problem.

Half the screen is black


The white dots are most likely to be failed pixels in the LCD screen. When the picture elements fail, they switch to clear and what you see as white is the backlighting.

The overheating issue in laptops is generally caused by dust and fluff blocking the cooling fins and ducts or a failed cooling fan, but it could also be caused by a hung process which runs the CPU at a high processing speed. Press control (CTRL) ALT and DEL and look at the task manager and see if you can see any processes that are running constantly near or at 100% to eliminate this being the problem.

The failing display is unlikely to be related to the overheating issue.

Black box blocks out lower half of television screen


Check your closed-caption settings. If you have captions on and set to "text" mode, this can happen. The TV blanks out the area on the screen where the text should go, but there's nothing to display. Turn off captions or set for regular caption mode, and that should clear up the mysterious box.

42 PHILIPS PLASMA HDTV 42PF7220A37 Hello, The top half and sometimes the bottom half of the screen would go black now and then, now the bottom half is distorted and theres some issues in the upper half...


Download philips latest firmware here: Click sometimes glitches can be cleared with their firmware. Also this could be a sign that your vertical buffer drivers are over-heating due to a faulty Y-sustain problem. The best way to check is to remove the back cover turn the TV on and see which buffer IC is getting red hot by touching it. Be careful as the voltage levels are dangerous, get someone who's technically proficient to do that little test for you....

Dell Inspiron 2200 monitor issue


Could be that the monitor is going out, but it sounds more like a connector has worked loose or corroded and isn't making a good contact. Check and clean the screen connection, screen to inverter, and screen to motherboard.
