Question about Multimedia Projectors
Picture not playing sound is
This can be any number of things. Your description from a technical point of view is very vague. It is sort of like calling a doctor and simply saying I can talk and walk, but something is hurting.
Some basic examples that can cause no picture:
Main power supply failure.
High voltage supply failure.
Short on one of the boards, or a scan failure causing a protection shut down of the high voltage.
Set is in protect mode due to one of the above failures.
On each of the boards involved there are hundreds of components that can cause your symptom. The set would have to be properly diagnosed by an experienced TV tech who is used to servicing the type of set you have.
