Any help would be great here.
I recently got a new (well refurbished) Packard Bell A726 monitor. Tonight while using it the screen started to waiver at the sides, I was concerned so I lowered the refresh rate and the resolution (Even though I was using it well within its limits) then I got that horrible burning smell (you know when some of the components are melting) as I went to switch it off there was a small bang and a flash of light form the side of the monitor. I switch it off and plugged in my old monitor to check the rest of the pc was ok (its fine).
Now when I plug the Packard bell in to the computer the frame stretches beyond the screen and any windows on it are horribly pin cushioned. It still reacts when I change the settings in win98, but it doesn't respond to the monitor's own control panel. e.g. nothing happens when I change the h.size'position etc.
Does anyone know what has happened and if it is easily fixed.
Has this happened to anyone else.
Is this common with Packard Bells/refurbished monitors.
As I said a the start I would appreciate some help here.
 
I have that problem with a different type of CRT. One of the difflecting amps burned out. My best solution would be to just trash the HP monitor.
 
Professional repair (US) will probably exceed 70.00. May be time to get another monitor. And I regularly pick them up near the repair price.
Waver on the sides probably is a failure in the horizontal output, which in turn causes high and low voltage problems.

Any advice I give is my best judgement based on my interpretation of the facts you supply.

Help increase my knowledge by providing some feedback, good or bad, on any advice I have given.

 
You should know that refurbished monitors are made by taking 100 defective monitors and making 30 good ones from all of the used parts. And, typically the repair places do not burn them in. They change parts until it works and then pack it and ship it. We often find as many as 15 bad capacitors in a monitor. Replacing one may fix the monitor but it is likely to fail early in its refurbished life. We check all caps and replace any that are week.

The burning smell may make this one an easy fix and it could be as simple as a bad connection but unless the repair person does a full evaluation of the unit and upgrades it as needed you might be paying $70 for a monitor that fails a month after you get it back.


 
Especially Packard Bell. Weren't they notorious for bad power supplies?
