I am replacing a blown capacitor on my LCD monitor power supply board. While I have the thing in pieces I thought I would replace the other electrolytics as well as they may well fail in the future. However one of them is missing part of its value and I'm hoping that someone will be able to help identify it.

The capacitor is rated at 50v and the part of the value that is visible is possibly 8uF, however the characters before are missing (the plastic sleeve is damaged). Physically it is 10mm high, 5mm in diameter. It is part C824 on a Digital Decode Ltd P/N BLM1700P60411 board. It is adjacent to the 817c optocoupler.

As I said above it looks OK so if it can't be identified I'll just leave it and hope for the best.

    \$\begingroup\$ Possibly 68uF? That's the only standard capacitor that comes to mind with 8 at the end. \$\endgroup\$ – Gustavo Litovsky Feb 25 '13 at 20:55

    \$\begingroup\$ @LeonHeller: Where's the ultimate decision that repair questions are off topic? It's ridiculous to ban these questions from EE. This question is a component identification question as well. \$\endgroup\$ – Gustavo Litovsky Feb 25 '13 at 21:17

    \$\begingroup\$ A quick search shows that this particular board (also known as PI-SB02) is commonly used in many monitors, and is widely available as a complete assembly for $20-$30. You may want to just get a spare and be done with it. \$\endgroup\$ – Adam Lawrence Feb 26 '13 at 13:12

It's 10µF (PI-SB02 REV1.3)

Quick look in Farnell for 50V, 5mm diameter, radial leaded cap gives only three possible values: 0.68, 6.8 and 18µF. 5mm diameter caps end at 33µF so I doubt it is a 68µF.
