IBM CRT Monitor - monitor off, red LED flashing

My monitor worked great for 4 years now, suddenly it didn't wanted to connect to the PC, although the Video Card was OK. The red LED was on so it isn't a problem with the power supply. It recovered in a few days then went off again. And now the red LED is flashing instead. I don't have any experience in repairing monitors, though I have repaired electronic appliances around the house like recorder, phones, washing machine and stuff... Can I fix it myself or do I really have to get a repairman?

Ibm e74 17 crt monitor screen is black with the indicator light flashing green.

after 4 or 5 yrs EHT ( transformer that supplies voltage to CRT TUBE - MONITOR TUBE ) becomes weak - then 1 of the indication is ....monitor LED just blinks & no display solution is EHT ( also called as flyback transformer ) should be replaced....... {{ few details about EHT---- its size will be around 3inch X 2inch X 2inch ---it will have 2 or 3 knobs to adjust focus , brightness ------ at bottom around 10 pins will be there ------- from EHT 1 thick red colour cable goes to CRT TUBE --------- on EHT its part number will be there }} -------- so if user is a technical person having idea about components ( resistors, transistors, diodes, etc ) , having tools like multimeter ( to check components) , soldering iron, soldering lead, flux, desoldering wig ( for removing components), etc also little experience in servicing field( very much compulsory) ----------------- then user can remove EHT from main board ---- take to electronic shop ----- buy same type EHT --------- fix to mainboard ( knobs on EHT should be adjusted according to picture --- after switching monitor --- this adjustment is very important ) ----------iam from bangalore (09986222774, ----- here EHT's price will be around Rs 250 ( US $ 6 ) & for my customers (in bangalore) i will take another Rs 500 (US $ 11) as service charge......i don't have any idea about EHT ' s price & service charge in your place.........since it is very risky job i suggest to contact monitor service engineer ------- because they are highly experienced & can fix this component very easily.... SOME TIMES ALONG WITH EHT....A TRANSISTOR ( BIG IN SIZE & FIXED NEAR EHT) ALSO GETS DEFFECTIVE...........SO IT SHOULD BE COMPULSORYLY CHECKED BEFORE REPLACING EHT

My E771 monitor colors suddenly shifted with

1. video-card gone bad;
2. video-cable gone bad;
3. video-cable not tightly-connected to CRT;
4. video-cable not tightly-connected to video-card;
5. "red" gun inside CRT gone bad.

Disconnect the video-cable from the computer, and try again to adjust the "red". If red-free, then it's time to responsibly recycle the CRT.

Reconnect & wiggle the video-cable, to see if that induces any "red" onto the CRT.

Connect the CRT to the VGA-output port on a notebook computer, to see if that video-card generates "red" as one of the primary colours.

Give the CRT a strong "whack" on the side, to see if "red" makes an appearance.

Sir Help me with my Compaq monitor MV520 it won't turn the power led flashing orange to green continously

it could be th epower supply and it could be the monitor.
power ON button should not flash orange regardless what you do. it should stay green. then orange. not orange to green to orange.
try the monitor on another PC if you can fine one.
the other thing is are the 2 monitor similar (CRT to CRT and LCD to LCD), you can't mix the the two, they will work but need different video driver to function correctly.

Ibm 14"crt monitor white light is blinking screen is blank

The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

  • Video cable.
  • Video adapter on PC (sometimes integrated on motherboard)
  • Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Flashing Green Light on mx705 monitor

If the HP has onboard video but you have an add-on video card, remove the add-on and connect the monitor to the onboard vid. If it works you have a bad add-on video card. If it doesn't or you are already running on on-board video hook the mx705 up to a compatible HP. The older PB may be TOO old to handle it or not hve the correct drivers.

Flashing monitor

the ram itself is not related to your problem, but check the VGA lead connections at both ends and see if the connection is loose and also check the power cable. Other than that it may be the monitor circuitry or CRT itself thats the problem and after warming up the problem goes away, so a repair may be needed or a replacement monitor.

LG Flatron 795FT - Led blinking

there is a step by step procedure 1.check the power cord. (try with a new one) 2.check the monitor on other pc, even if it is not working on the other pc, then carry to a service centre. 3.if it is working on the other pc then check the vga slot/card of your pc then 4.try to change the vga card and try connect an other monitor to your pc. so basing on this you will be able to trace the problem. 5.still the problem persists the consult the service centre.
