Default Re: Acer GR235H partially losing backlight

So plot twist, I've ripped it apart and found a bloated pair of Su'scrud caps. Unfortunately my picture-taking capabilities are about as high-quality as these capacitors, but it looks to me like they feed into the 2x OZ9998GN backlight drivers. Do you reckon it's worth recapping these and seeing if it fixes the issue (I'm just wondering what the odds are of two LEDs going out at once!).

The board is an L0256-1M, and doesn't seem to have been documented elsewhere on this forum. C121 and C818, screenprinted back and front on the board (corresponds to bottom-right of rear photo).

EDIT - added a better photo of the circuit
