If its a vfd (vacuum fluorescent display) try looking for an e-cap on the vfd board and change it.
I learnt this from my old boss back when he was repairing VCR's 20 od years ago.

Andy Shiekh,
thanks for your input,Silicone oil is dielectric works good as insulator grease & Lubricating but doubtful that it will prevent further oxidation with good Electric conductivity.

Thank you! Toyo,
i just cleaned it with IPA, not familiar with the product which stop future corrosion & same time allow proper electric conductivity.

The rubber contact strips also can be found in older lcd watches.
