Default Thermador Oven Controler Dim display

Hello everyone,
I'm trying to repair a Thermador 486752 Oven controller. There are many posts on the internet about replacing bad capacitors but I can't find the actual value for the Caps. I pulled the board out to look for myself but I can't see the value unless I de-solder the component (it's in a tight spot) I would appreciate any help I could get. I have attached a picture of the board.

Thanks in advance

OP, can you switch off power and try using a small mirror? Also, measure the diameter of them. They come in standard sizes like 8, 10, 12.5mm etc.
edit: also a cellphone camera pic can work, just stuff the camera in there in macro mode and you'd be surprised what they can capture.
I can read the capacitor part values and size from other pictures on the Internet but do not want to post the wrong info and cause confusion.

Thanks very much for the reply. I did try a small inspection mirror and I found the value of 2 of the three caps. the last one (c3) is pretty tight to the transformer and looks like it may be 3300 Ufds. so far I think I have
(1) 100 ufd 50V
(1) 470 ufd 16v
(1) 3300 ufd 16v (best guess!!)

Thanks again for your suggestion it helped

OMG price gouging for these boards is criminal!
Repair your oven control board by replacing $5 worth of capacitors! Just to stop from throwing the whole appliance away.

Oven/Range Control Board - Thermador 486752, Bosch 35-00-571, 14-33-347, AP2836528, 487604.
The board is made by OEM Robertshaw, design used in many different makes/models of ranges.

Same power supply section as Frigidaire, Kenmore 318012903, 318010300, 318010101, 318010102 which gets the cheapest Lelon capacitors

We're only missing the one cap value at the side. So far I have:

C1 3,300uF 16V, size skinny 12.5x25mm LS=5mm
C5 ?0uF ?V, size 10x?mm
C8 470uF 16V, size 10x20mm LS=5mm
C9 100uF 50V, size 8x11mm LS=3.5mm

Can you see any writing on C5? I can then give some part number recommendations for replacements.
