We have a mitsubishi HD 1080 series rear projection tv made in fall of 2000. the DVD player thru component video works fine on either 1 of 2 component connections. Every other connected device including games, cable tv, and Roku (thru component or red white sound yellow video) work intermitently, then screen goes blank with about an inch of screen visible at top only. struggling with what to do - I opened back, no obvious loose connections. Ideas? I certainly would appreciate specific direction to a fix that saves me from bringing the huge tv into the repair shop - is there an adjustment to make? is there a likely component or board that is at fault here? Thanks

Simplest thing would be that your component cables are not HU'd correctly. Having them reversed would do this.

Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

Does the input menu appear on the screen when you press input? If so its probably the IC Regulator 9v supplying the video board. If the green light on the front is blinking then powering off it is one of the 7 capacitors and you should just replace them all, 30-35 bucks. If the power stays on and its just your video isnt coming on(audio as well) it is the IC Regulator. Mine called for the part - BA09FP IC REGULATOR 9V It is about half the size of a pinky nail and located directly behind the video input board in the back of the tv. It has two prongs on the left side and one wide tab on the right. It solders directly to the top of the board and not through it. It says BA09 on the chip. This fixed the problem for me.
