hiya,

my brother has a packard bell CRT monitor that is only about 6 months old for 'what i can see' no apparent reason.

the problem with this monitor is that about a week ago it started cutting out (i mean totally powering off) when he tries to do anything with it and not just playing highly powered games. it is not a graphics card problem as i have tried the card in my machine and its fine. the native resolutions have been set to 1280x1024 which is appropriate for the card installed. i've tried lowering the resolution but even that doesnt seem to work.

please help as my brothers going mental at me because im not qualified to take these thing apart. i dont know what is causing the problem. :sad:

Brief, practical rundown to complement the replies from , and others.

Because reports the card is known-good and the symptom happens across machines, the fault is most likely in the monitor itself or its mains/power-handling circuits. The following are safe, non-invasive checks and the key observations to collect before contacting support or a repair shop.

  1. Precisely note the failure mode (record on a phone if possible): does the power LED go out, or does the LED stay on while the screen goes black? Is there a click, hum change, smell, or heat build-up? Does it restart automatically or only after unplugging?
  2. Power isolation: try a different known-good wall outlet (not a UPS/surge strip) and a different mains lead.
  3. Monitor-only test: with the PC off, power the monitor and leave it for 30–60 minutes to see if it still dies with no video input.
  4. Video/sync check: try a different VGA lead or adapter and set a standard refresh rate (60 Hz) and low resolution to rule out sync/EDID issues (this is different from only changing resolution).
  5. Environmental check: ensure vents are clear and the monitor is not cramped; note if failure happens faster when the room is warm.

How to interpret what you see: LED extinguishing or audible relay clicks that coincide with power loss usually point to the internal power supply or thermal/overcurrent protection. A steady LED with image loss points more to deflection/video circuitry. None of these are safe to open at home.

Next steps: gather model, serial, purchase date and the failure log above, then contact Packard Bell (warranty/RMA) or get a written repair estimate from a qualified shop. Repairs on CRTs often approach or exceed the cost of replacement, so compare quotes before authorizing work. Do not attempt to service the CRT yourself; as warned, capacitors and high-voltage parts can remain lethal even when unplugged.

Ok, I know you've tried moving the graphics card, but have you tried moving the monitor to another PC? Have you done the obvious checking of the cables, both power and the pins in the d-plug? I have seen monitors go 'bad' in shorter time frames than this so it could be legitimately dead. I wouldn't recommend taking it apart, they never end up being the same anyway, if it survives the surgery.

So, try moving the monitor to another PC and using a different power source then let me know how it works out.

thanks for your advice wally. the monitor cuts out on all the machines i have apart from this one that i am using to compose this reply. there doesnt seem to be anything wrong with the cables or the power supply. im baffled

Seems like the power supply on the monitor might be bad. This is actually a fairly common source of CRT failure. If it's still under warrenty, get the monitor replaced.

Is replacing the power supply costly ?
What % of the monitor cost is the estimate ?

NEVER touch the components of a CRT. just go and buy a complete new one

Yes, you are likely to kill yourself if you do. Get a new one
