Open Question

Thomson 28WF64U crt 100Hz. white pixels comes & goes after period

Some times this CRT based 100Hz TV will function correctly all day. The next individual white square pixels appear. Some times in lines, sometimes around the outline of objects or both. This problem can fade to nothing then the picture can get so bad as to be almost unwatchable. The next day be fine again with no problem. This only started recently but is becoming more frequent.
Anybody any idea as to which component may be at fault?

HI. If it is not a problem with the CRT itself, look for bad solderings on the CRT socket. If it is in the CRT, you have very bright green with white stripes across.
