Question about NEC MultiSync FE2111SB 22" CRT Monitor

1 Answer

Small colorfull,verical lines on my COMPAQ V70 monitor.

I have a 17" CRT(cathode ray tube),COMPAQ V70 color monitor.It was ALWAYS running great,pruducing superb imeges.But recently,some small,vertical lines or some wave-like shapes appear.They really don't bother me a lot,but i have seen similar cases and usually it leads to even more complicated problems.I took my monitor apart and tried to see what might be the problem.But i didn't find any problem,everything seemed to be okay,but i noticed something strange:i have two speakers to the left and right of the monitor,and when i move the speakers,the lines change their position...so it clearly is a shielding problem.But from where?? If anyone knows what it might be,please tell me. Thank You for reading!!!

    If you have access to another monitor, we can quickly rule out a number of things. 


    I wonder if your video card in the PC is the problem. What video card is in the PC? Sometimes they fail. 


    Physically unplug your speakers power. Wavy lines still there?


    Lastly... I used to deal with these monitors quite a lot at work. They had a higher than normal failure rate and we always seemed to have 1 or 2 out being repaired out of the 1000 or so we had.

    My monitor (CRT) only has half a picture--the top half is not projecting; I heard you might solve this by "zapping the tube" which allegedly knocks off extra electrons that have accumulated. What doyou think.

Open the monitor- with a wooden stick, or rubber eraser end of a pencil, gently poke and press on different areas of the boards, especially the neck board [the one the crt plugs into] - sounds like you may very well have a bad connection, especially a groung connection.

My IBM c170 crt show differents colours(yellow,pink,red....) on display plz help me


omg, a CATHODE RAY TUBE not Crushed yet.
raise the flag, get a medal of honor.
my guess, ?
( I did crt from 1965 to first flat screens) even RADAR !

you are lucky its still glows at all. no , really !
no photo , no guess. sorry, the examples of bad presentations
on any screen, made is near infinite. only photos work.
some CRT had a color bar test mode.
so turn off the test switch.
you never said what it was plugged into? Windows 3.12?
if its a mushy blob of colors? a blob like of stated 3 colors
wel, that is the newer TV stars, riddled with ugly nasty tattoo's.
find a new Youtube channel.... LOL

Monitor image is "posterized"...red,yello, blk and white only


you have defective RGB circuit, or re solder all CRT Board maybe you have lost contact at the RGB CRT Board. RGB means red, green, blue. CRT means Cathode Ray Tube.

Unfortunately, this is not a fixable problem. Samsung CRT monitors are well known for losing color; they have defective cathode ray tubes. I recommend that you buy an lcd screen. sorry if that wasn't what you wanted to hear! don't forget to rate

Screen is whitish and its blinking with white lines


The Cathode Ray Tube (CRT) can develope a short circuit in the neck area of the tube that will cause this. I suggest that you remove the plastic cover of the monitor, and tap on the neck of the cathode ray tube with the plastic handle side of a screw driver. Be careful while the cover is off of the monitor not to touch any wires or the high voltage wire that connects to the side of the tube. There is very high voltage used to operate the CRT and it will zap you!!

Compaq 21'' monitor power supply led is not working


I didnt know they still made cathode ray tubes. Id suggest you junk that thing and get a decent LCD screen.
It is beyond the scope of this website, and possibly your skills as an electronic technician to go through complete troubleshooting scenario.

My monitor model.No 700E i Start My Moniter showing Yelow Screen


You could have a bad cathode ray tube or you have a bent pin on the VGA cable.
this could also be due to a color correction circuit on the monitor circuit board.
Your monitor may also have succumbed to age.

Please tell me what is flyback 1600V working voltage PF (near the horizontal transistor)


Hi

Flyback is a step-up transformer multifly the voltage depends on the size of the tube and supplied high voltage to cathode ray tube.The minimum output voltage of this is 14000v DC for 14 inches crt monitor what if your crt is 17 inches 17000v DC very dangerous if you are not electronics repairman.

Crt monitor video chroma processing


first you check the signal cable continuty by multimeter then correct it if faulty .if ok then give -ve click at red cathode on crt base in on condition if red raster comes on screen then red cathode is ok same thing for green and blue cathode if green cathode do not shows green raster after -ve click then crt is faulty then give -ve click at R point at color raster ic which has heat sink if red color comes then ic is ok same thing for green and blue if ic is faulty then replace it if not then check bipolar capacitor if faulty then replace it

Red colour missing


- A bended color pin at the VGA connector. (If pin one is bend then there would be no red color)

- A defective VGA signal cable. If the internal wires were broken then there would be missing colors. You can check if the signal cable is good or bad by doing a continuity test using a multimeter.

- Dry joints in the CRT board such as in the CRT socket pins, video pre amp and driver IC and even at the connector pins. In fact this problem contributed about 80% of Monitor color problems. Applying fresh solder would usually solve the color problem.

- A defective IC either in the Video Pre-amp or Video Driver IC.

- Faulty components in the CRT board. It could be a shorted driver transistor or even electrolytic capacitors that the ESR reading had shot up!

- A bad CRT socket. Sometimes decayed glue could cause the internal pins rusted and thus affecting the colors. Replacing only the CRT socket would definitely solve the problem.

- A weak or a defective picture tube (CRT tube). Yes, I do came across one of the electron gun (most probably the cathode materials had used up) in the tube faulty caused a missing color in the screen. There’s no way to repair this type of problem-the only way is to replace the CRT tube.

- In the newer type of Monitor, color setting is save in the EEPROM IC . Thus, if the EEprom data is corrupted, you would also get a missing color! The only way to repair it is to reprogram the IC or use a soft jig to tune it back the color setting.
