Question about Hitachi 46F510 46" Projection HDTV
The coolant most likely needs changing in the CRTs. Another possibilty is the mirror has become dull. use a damp soft cloth to clean the mirror then dry also clean the CRT lenses . Dont use windex. You will be amazed the difference just polishing the mirror can make in picture quality. Looking into the CRT lenses while they are on will tell you if any groth are present in the CRT coolant chambers.
