Cap kit for Sony PVM-2730QM

[PascalP]

So I’ve got a PVM-2730QM which has some terrible geometry and adjusting it as good as possible still looks like crap, so I think it is due for a cap kit.
Has anyone done this before or is there a cap kit / list available with all caps needed to get a proper geometry.

I could go ahead and replace just every cap in it, but then we’re talking about a few hundred caps going by the service manual.
Would take me days just cataloging all caps and getting them, not even thinking about the costs of all these caps…

You generally only need to replace the electrolytic capacitors. I would assume the service manual lists all the caps without specifying what type of cap it is.

As for cost, caps are dirt cheap. They'll usually set you back between 10 to 50 cents a piece.

Yes, I've done many caps before on PCB's and arcade monitors, average about €0,25-0,50 a pice.
But That's 20-30 caps max...
If we're talking 200-300 caps as in this PVM, the numbers change quite a bit

I think I'll just open the PVM and start with searching all electrolitic caps on the PCB which controls the geometry and perhaps the caps on the neckboard.
Should be a good start right?

my advice? replace all the electrolytics, close it back up, and dont touch it for another 20 years.

your eyes will thank you for the cap kit.

That's is my plan yes.
I just finished indexing all the Electrolytic caps according the service manual on the neckboard and the pcb's which control the convergence and geometry.
In total it is 80 caps, I will crack open the monitor to verify and get me some caps

For those who are interested, this is the list of electrolytic caps on these pcb's:
