[QUOTE="2cvbloke, post: 930088, member: 199791"] Capacitors are reasonably priced, yes, but like I say, working out which one is the problem (assuming it's not a software bug that Sony missed/couldn't be bothered to fix) as I've said a few times, to find a bad cap that looks okay requires their removal and testing with an ESR meter, replacing them willy-nilly can be a wasted effort if it isn't one (or more) at fault, and if inexperienced with capacitor removal and replacement it poses the risk of permanent damage to the PCBs... But as for which ones you need, you need to look at the ratings on the sides of the existing ones, for example a capacitor of 1000µF 6.3v 105°C should be replaced with one of the same rating (you can go higher voltage rating, but keep the capacitance, the µF (Micro Farad) value, the same) and same lead spacing (the distance between the pins of the capacitor), and try to pick 105°C capacitors as 85°C ones are prone to failure in hot environments. The type of capacitors you are after are mostly Electrolytic capacitors (as opposed to film, ceramic or tantalum types). And as for brands of capacitors, personally I prefer Panasonic caps, but other have their preferences... [/QUOTE]
