What size bolts do I need for attaching the stand?

you to tel me what you want ok you want a tv stand do you need to locate where you can get one or what?

You remove the high pressure line using a standard imperial open ended spanner on the fitting where the steel HP line attaches to the PS pump unit.. It will most likely be around 5/8". But, if not that size, if you have a decent range of imperial size open ended spanners you should have no problem finding one that fits perfectly. If you don't in your spanner set then slide an adjustable spanner over the fitting, adjust it up to the bolt on the HP line and then remove and measure the size. Buy a spanner that size (the longer the better) and you should have no issue removing the line as long as the bolt head has not been rounded off.

Contact the authorized dealer for Magnavox. They can help you.

Take the Stand to the hardware store and have them try a few sizes that fit. You need Machine Screws and who knows what length?

while the owner manual does not specify the length etc of bolts it does show there are 4 of them---look like find thread machine bolt---may be able to buy a few at the hardware sore or Home Depot---if the threads are inside the base take it with you as a guide.

pretty stupid as owner manual has everything including dimensions and weight etc but no list of bolts size.

You will use the bolts that you take out to remove the base from the tv.

if your GF wants you to separate the three in one coffe what well you do?

I assume that its Sony KDL-40S2000 model and it needs following size screws to attache its table stand..
