I am working on a JVC NV-55BX6. This unit has a weird symptom. It does not have a distinguishable picture. It's like there's a blob on the screen in the middle. The audio is fine. You can see some colour around the blob but even the colour that you can see is not a very distinctive picture. If I switch to the A/V input, the picture is all white. you cannot see any on-screen display. Just wondering if anyone else have had this type of problem! What part(s) might cause this?
