A worm drive will always yam the loading mechanism. It is impossible to turn it from outside.
Or it will break by forcing the cassette into the VX. What happened…
This is the trigger to load a cassette… moving the cassette 15mm inside the loading mechanism will trigger the switch on the drive board…
There is the 12V power regulator. It becomes really hot, even if the VX is ok and in standby. 60 degrees are quite normal, consuming 20W in standby… that’s a lot…
That’s why this VX had only a lifetime of some hundred hours. I had some VX5000 not surviving the first year in 1988…
The VX can be modified to save power. But this is a complete and very radical modification. A modified VX5000 consumes less than 10W, the VX7000 can be less 5W…
But… you can remove the analog tuner as a first step. There is no analog radio station on this planet any more… so, it’s a waste of space and electricity… and inside the tuner are also defect caps … 😉
Do you see the missing tuner? It is not necessary at all… just remove it. This works for the VX5000/5500/7000… less is more 🙂
Remove the tuner… or repair it. And when it is repaired, why put it in again? It’s a useless part…
The metall box is the head amp.
Important for noisy pictures and missing sound. It decodes Picture and Sound from the tape… just tape playback and record.
If sound is bad even from AV decoder input, it’s something else defect, not the head amp. (VTAPE – Shift 7 for input….). Worth testing…
But… the front panel has 2 linear potis for recording. And 2x mini 1uF or 10uF caps exactly for recording left/right next to the potis…
As i said, the VX5000 has a lot of caps inside…
Have you made the digital unit already? Can you activate this unit? MX5000 or MX5500?
There are a lot of them in a very special size of RM 2,5mm … very special and really very hard to get in this size. RM2,5 is usually no problem, it’s the mechanical size of them, some are bipolar… that’s why they are red now 😉
All video signal runs through this unit, even if no digital effect is used. Just pass through…
The small board above is the text overlay for the menu. Already done? RGB working? The size is there more than critical, every millimeter counts… i use meanwhile SMD R7y bipolar caps for the RGB unit…
Original function of the signal board of a VX7000… repaired, restored, working, 100% function like it was 1989…
Modified board, repaired, 100% functional with satellite unit using the auxiliary port … and 50% less power consumption.
Original upper VX7000 board with useless analog TV tuner unit…
Modified upper VX7000 without analog tuner, no multilingual analog tuner, using satellite digital unit and can record it.
Critical capacitors? On a VX5000?
That’s easy. 100%
Around 200…
Which one on this picture would you like not to replace? They are all dead.
Repairing a VX5000 means 100% replacement of all caps. Not even some percent. It really means 100,00%. Or dont start …
All caps in the VX are leaking. This board is complete dead and cannot be repaired. The acid has done it’s job. The copper is gone.
The counter is inside of the drive wheels… an optical sensor.
And it will not run without it.
But in the VX setup you can select “Counter” and “Title Counter”… 😉
And the “title Counter” will only start counting with a completed 100% rewind of the tape. It will not cound in the middle of tapes, just from the start.
