[REPAIRED] Konami The Simpson color error on tiles

[Tailsnic Retroworks]

Hi, I am trying to repair a partially broken Simpson board. It has the error of not showing good the palette colors on tiles. The sprites are drawn correctly.

Checked the palette rams, the 3 x LS157 near the 053251 custom and 053251 itself replaced. Where should I go check?

Could they be the culprits the 2 customs in charge of the tiles' section?

Repaired. Culprit custom 052109, replaced and thanks to it, I could see test screen for a broken tiles' mask.
