Testing V,H.F. today and found screen not working properly. Do i need to replace same and if so can i replace screen only?

Best of luck. You will need it.

I have had this problem.
You can take the front of the unit off after pulling off the control switches and unscrewing the fixing scrws,carefull with the connecting forks when pulling appart.I expect you will find the larger connecting strip connection will be furred up. I cleaned up both connecting surfaces, applied some silicone grease and put back together, now OK.
I would also take out the "O" ring seal between the face and main unit, clean silicone grease again and reassemble.
Hope this helps

Had the same problem at the end of last season - lost most of the pixels and couldn't really read the display.

Was all set to take aprt and fix as suggested on other posts. However, I left it over the winter. The boat's stored in a garage and it must have dried out, because it's worked fine this year. However, I'm a LOT more careful when washing the boat down. I keep the hose well away from the VHF in the console, whereas before I used to just spray away merrily on the understanding that the VHF was waterproof. Someone also suggested removing the radio and putting it in an airing cupboard for a while to dry out, but I didn't need to do that.

You might be lucky also, but who knows whether it's a long term fix...
