Help with repair of Turbo Express

lol, i checked the chart before responding.
everything with a 900 number relates to backlight
500 is power supply Q506, C506, VR500 -24V/ VR501 +5V
700 series is logic/chipset ect

Cool.  How about the pin out for the board side of the AC adaptor jack?  The traces are really bad in that area on mine so I can't really see how to fix that at this point.

One time I had a TE that was acting up like yours. I smell something burning. I opened it up , fired it on and saw smoke coming from the transistor near the cap you mentioned. I had a short across that cap. Sure enough I saw a piece of solder wedged between two contacts of the connector that the controller pcb connects to. I remove the solder piece and that cap no longer shorted. Funny thing the fuse didn't blow and it works just fine after that.

My TE Video has died. I changed the Caps as I had the Dark Screen issue. Now everything is unchanged after  a complete Recap. The Unit works, Sound is there but the Backlight is only very dark, Constrast Adjustment does nothing. I decided to create a "Check your GT Testpoint-Values" Spreadsheet. Here are my values - Excel-Sheet on Fileupload:

The Chart is not complete yet, so please feel invited to add working Values and fault Values. Maybe we could create a Quick-Test System: If TP 50X shows that Value, Part no XXX is broken/trace is dead.

I need to find out, why -24V are missing and why Q500 / CC501 /L500 are getting hot...
