Question about AOC 177S-1 Monitor

1 Answer

Sometimes my monitor screen turns a pinkish or purplish color. This may last for a minute or two and then it corrects itself. Do I need to replace a bulb? Which one do I buy? Or is thi another problem. By the way, the pinkish color makes it very hard to read.

Cwtigress122, Try this first! With all power off. connect and disconnect 177S from the pc several times, then when connected power up everything and see if that cures your "pink or violet" screen. If that not cure, then your unit may have bad "switch-mode-power-supply" and you will need to make decision to fix / refurbish or trade unit for new. Your unit listed as "over the hill" and "time to replace" on retrevo .com!!! Also visit YOUTUBE for video clips of owners/technicians that refurbish their units back to life for 1-3 years more use, to see if that is option for you.

Monitor displaying purplish colour and sometimes blinks


Have you checked the cable that connects from PC to monitor ? If its VGA, it will be a 15 pin cable. please check both ends of the cable if any PIN is broker or bended. or remove it and tight it again. If that does not solve, the monitor will have some hardware issue.

Pink Monitor


Hello,

Are the monitor and computer both new or are they used? If the monitor is used then I would bet the problem is the backlight tubes. The backlights in LCD monitors are fluorescent lamps just like in your house or office. When the bulbs get old and about to burn out the output light changes from white to a pinkish color. At this point if your monitor is several years old and you have a pinkish display you need to start looking for a deal on a new unit. It is possible to replace the tubes but it is very hard to do because they are so small and fragile.

I hope this helps.

My l g monitor screen suddenly turned into pinkish colour..i dont know whats the problem..i did degaus also but no use..


Dear Sir
Welcome to Fixya Customer Support
We will Help You
Generally this problem arises due to faulty monitor Signal cable or by broken fins of VGA cable.check your monitor connectors for bent or broken pins. usually happens after swapping cables or monitors on a computer.you could also have a bad cable or monitor.

Is the monitor a CRT or a flat panel.... loss of one color is very common on CRT monitors, and could be a bad solder connection on the CRT driver board, or a bad video chip..... flat panel LCD monitors don't usually lose a color, although it is possible.... the most common failures on LCD flat panels is total power supply failure (no power at all) or display matrix driver failure (colored stripes across or down the screen), but a cable failure is also possible, like i said above, check the connectors for bent or broken pins..... there are 3 rows of pins...... at the widest side of the connector, there should be at least 3 pins next to each other on that row (sometimes there are 5), the middle row should at least have 3 consecutive pins as well (and again, there are sometimes 5)
the last row (the smaller side of the connector) should have at least two (but sometimes all 5) pins in it. the first row and last row of pins should line up vertically, and the middle row is offset a half a space, so from top to bottom, the columns of pins make a zigzag...... if the connectors are alright, then your most likely problem is the monitor..... if another monitor works on the computer, it's the monitor..... if another monitor has the same problem on this computer, then it is the video card (or the motherboard's video output, which is fixable by installing a video card)

You have a bad connection on the CRT board thats mounted on the end of the picture tube it sounds like, or the socket on that board that plugs into the TV set is intermittant or has a bad solder connection on it. Good Luck
