"Dead spots" on a monitor

Post by Alec » March 1st, 2009, 1:56 am

Hi everyone.

I just bought a monitor and had it shipped to my house. I'm powering it up for the first time and there are some small black spots on the screen where the pixels do not light up. About 4 or 5 in total. The monitor frame was all bent up when it arrived. I have a replacement for the frame, but I know it was a rough journey.

Does anyone know if there is any fix for this problem? Or at least what caused it? I'd really like to save this tube because its otherwise brand new.
Thanks in advance.

get a replacement sent-sounds like it has been dropped badly
pixels missing normally is down to real bad build quality in the first place

This was the replacement sent :cry:

I actually have another tube that will fit this cabinet in the house still, but the pins on the neck are not the same. Would there be any way to fit the chassis to that tube? This monitor is a Sanwa PFX29-46. The extra tube I have here is a Samsung A68 tube from an Atomiswave cabinet.

all depends on yoke specs and crt specs but i doubt they are compatible-you will either have to live with it or get a replacement sent

Bummer. I mine as well mention that theres also a bit of discolouration in the tube, more than likely from being dropped. Just for everyones reference, here are links to some pictures I snapped to show the seller. I've circled the spots on the monitor. On further inspection theres more like 20 spots, not just 4 or 5. Its a Sanwa 29PFX-46.

They must have dropped that realy hard... That looks like the shaddow mask has hit the back of the tube surface removing some of the coating.

I'm suprised the chassis and neck survived, there's bound to be some fine cracks that'll cause problems later..

Send the lot back and get it replaced.
