I'm celebrating because it took so long to find anything thats close to the schems for the 42H83 model. Thankfully this one has the same layout on the signal board. Problem now is knowing connection points that get soldered. Would it be obvious DUH? I did'nt finish my classes so I am ignorant when it's comes to reading these, so maybe someone can help.

lddude: I imagine that at every inline point there should be a soldered connection,like the crude example in black arrow. Although the pic i'm showing is the foil side of the board i'm thinking that my assumptions are right,please correct me if wrong. Jumping around the ground for the Hyper Module seems like rational thinking. Let me know, I'm always over thinking!!

Thanks for viewing,responses welcomed

I am not following your question. The diagram shows the traces on the board. You need to repair any broken traces but there is no reason to add connections beyond what was there in the first place.

Well thats my fault, your not understanding my query. Previously I posted the thread Toshiba problems and at the time I had not come across any schematics. The boards a wreck and in the earlier pics its hard to tell what is where. Since I don't have an Oscillascope to test any wave patterns, I'm really taking chances in this endeavour. Therefore I ask the questions and though it may be an obvious thing, I apparently need some sort of confirmation. Thanking you graciously for yours.

You really do not need a scope to repair damaged traces. You need to look at where the traces are supposed to be on the diagram of the board and make those connections. You just need a multimeter to check continuity.

I still do not understand what your question is at this point.

Just wanted to be sure of where to solder. You answered that and I'm thankful. Obviously the arrows are pointing to the right connection points.

I would not say that this is obvious at all. You need solder where there are components that need to connecto the circuit traces. If there is a component or jumper, it needs to be soldered. You find the paths of the traces with the board layout diagram and you verify the connections between components using a combination of that and the schematic.

You are right sir because on the schem sheet its saying that a chip jumper 1608 type is required at junction GJ201. Now i am confused because I can't recall if there was any component there or what a chip jumper is. Any clues?

A chip jumper is just a jumper in the form of a surface mount device.

So would you say that I can place a chip with no numbers on it or one that has a 0 on top wich I think means 0.00 being the same as having no indicator. Is that true?
