I trawled the net and forums looking for how to access the H-amp/V-amp/H-pos/V-pos settings on the PV500 service menu. I know how to access service menu 2 but where are the above options as there are only 13 options set out like the following: option 1 (01), option 2 (b3), option 3 (73) etc.Whilst I've worked out how to alter these options they don't seem to change the image in any way. I've found threads for the PE30 where the service menu access is identical to the PV500 and it appears the H-am=/V-amp options are actually on the service menu 2 so why not on the PV500. Does anyone know where these options are, why would they have removed them from service menu 2 when they were on the previous model. I'd appreciate any help as i really need to find H-amp.
