The Hantarex Polo 25" assistance

[robbo008]

Hi guys,
I'm having some issues with my Hantarex Polo monitor. The side of the image is curving in. After about 30mins of use flips back to a good image. Is this a capacitor issue? If so which ones might be causing it? I've tried adjusting via the remote but there are no geometry adjustments for that.

I've not done any recapping and not sure if a full recap is advisable?
Thanks,
Rob

either a bad solder joint, dodgy pin pot or failing hv cap
pin pot is on the east/west correction board mounted in the centre of the chassis - thats if this is a polo 25 or 28

Thanks for that. Would it be this pot here? Which HV cap were you referring too?

vertical lin in first photo, the teo pot in second photo are side pin and trap
i doubt its a hv cap but you would need a cap meter to confirm value and not guess
