Flickering screen screen keeps flickering like the pixels are jumping around, mainly when on internet and usually abut 30 mins after warm up, so bad it makes you feel ill, tried config no good, monitor is acer x193w, any help? thanks

Look for bad capacitors, that's generally what makes the pixel issues like this

There are long skinny light tubes behind the screen that use high voltage to operate. What you are seeing is what it looks like right before they fail. They can be replaced, but it is a big job.

The power source to the pixels is defective.

Is this problem on Google Chrome only? try microsoft browser and let me know the result, I would recommend a full scan of your system to rule out a virus. If it turns out Google Chrome is the problem uninstall the program and reboot the machine, now do a fresh install, it may fix the problem.

Your Bulb is DUE, you need to change it, Don't do it your self contains mercury. Your LCD is good IF you do not have bad PIXELS. This white and pink lines shows as pixel problem but it migth also short on LCD, if you placed something heavy on Laptop. You may remove and sent the LCD for repair or all laptop to tech.
You may also need to check inverter. I give service around the Country but it is up to you. My company name is JMC TECHS INC. Registered in Miami Florida. (Check SUNBIZ.com) jmctechinc@gmail if you like to contact me.

I HAVE THE SAME PROBLEM. TV WAS FINE UNTIL A FEW MONTHS AGO. OF COURSE ITS OUT OF WARRANTY. FROM WHAT I HAVE READ, AND BEEN TOLD, IT IS THE POWER SUPPLY TO THE UNIT. IT IS DEFECTIVE, OR IT OVERHEATS AND TRIES TO SHUT DOWN. A LAW SUIT IS IN PROGRESS AGAINST WESTINGHOUSE TO RESOLVE THIS MATTER. KINDA REMINDS ME OF THE XBOX 360'S WHEN THEY CAME OUT. ALL YOU CAN DO IS TAKE IT IN FOR SERVICE. OR, YOU CAN KEEP TURNING IT ON AND OFF, LIKE I DO. I HAVE HAD THIS TV ON ALL NIGHT BEFORE WITH NO PROBLEMS. AS SOON AS I START CHANGING STATIONS, OUT IT GOES. GOOD LUCK. WESTINGHOUSE WILL NOT EVEN EMAIL ME. I HAVE TRIED SEVERAL TIMES TO CONTACT THEM. I HAVE HEARD FROM THE LAW FIRM IN CALIFORNIA THAT IS GOING AFTER THEM. GO ONLINE, AND JOIN THE CRUSADE.

backlight, inverter or loose screen connector into system board

i have the same problem?

The problem in your tv is not external.
The problem is in the power supplies internal filtering.
On the primary side of the power supply main board you will find
a large electrolytic capacitor very near the fuse and the primary transformer( the small one). Next to this capacitor you will find a
large 5 watt diode.( black with a silver band at one end). Next to this you will find one lone 1/4 watt resistor. This resistor in conjuction with large electrolytic capacitor is responcible for the internal filtering of the high voltage side of the board. As your unit heats up( anywhere fron 5 to 30 mins) you will notice horizontal
flickering and prior to that red or green or even purple pixelation.
Check this 1/4 watt resistor for dark discoloration and or a bad solder joint on the solder side of the board. This resistor
is directly responcible for controlling the bias current to the high voltage regulators for the 160 volts DC. At no time should you handle or troubleshoot this board with the line plug in.
Even when this board is powered down that capacitor still holds a charge for up to an hour and can knock your you know what
in your sock. If you do not feel comfortable please take the board to someone else. Hope this helps.
