Screen series of coloured circles

The repeating image is a ghost image, and here is described what it can be. Probably if you solve this, you also solve the red-dot problem. If possible, I would suggest to replace the wiper blade.
Repeating images on laser printerThis likely means a faint ghost of the main printout at a distance equal to the circumference of one of the rollers or photosensitive drum.

Depending on where the problem originates, this could be a bad wiper (cleaning) blade, faulty corona, or incomplete fusing.

• If the distance between successive images is equal to the circumference of the photosensitive drum, it is a wiper blade, erase lamp, or corona problem.A residual latent image or residual toner is sticking to the drum and not being properly cleared.
  
  
• If the distance between successive images is equal to the circumference of one of the fuser rollers, then the fusing may not be complete due to damaged rollers or an incorrect temperature setting.

It is easy to determine where the problem is located: Interrupt a printout in mid-stride (where part of the paper is between the toner/developer and fuser. If the un-fused image has ghosting, it is a fault in the area of the drum

pls, soldiring his crt base, all pins

It sounds that there is some magnet near by TV that is affecting picture tube. Please remove any extra speaker or any thing that has strong magnet inside, unplug TV for 20-30 minutes, replug back in, turn it ON, hope that will solve your TV problem.
Thanks.

i would have a service tech check out my degaussing coil inside of the tv. hey, that was a great idea to degauss it bravo

NOT HD: Make sure red goes to red, white on white, and yellow on yellow, also make sure the switch that is on the xbox wire plug says TV not HD.

HD TV: Make sure red on red, white on white, yellow on yellow, blue on blue, green on green, etc. Also make sure the switch that is on the xbox wire plug says HD not TC

Hello Roloi,

This sounds like a problem with your yoke transformer. I would suggest having a qualified TV technician work on this problem, because it involves testing a component that could have dangerous current in it.

I hope this helps,

Thank you,

the problem is in your degausing coil and its circuit. probably it wont start every time you turn on you TV.

your problem is simple it is called colour patch. it is basically due to change in direction or you must have shifted or tilted. it might be due to magnetic effect like spkr,telephone near by it.just remove from that location. put of the set for 15 minutes &put it on .problem will get clear. ask tv tech. to degauss it by dega.coil.it hardly 1 second job. regards

Hi. The problem is either the degaus positor has failed which is an easy repair. Or have you recently placed hifi speakers or something with a strong magnet in side near your tv set.
