Clarion 8204R Power, but no light, no sound, only dimmed numbers.

Best regards, I'm Darren from Mexico, I'm fixing a Clarion 8204R for my father, actually was a stereo with amplifier, but inside has this car stereo clarion, wasn't set to ground, so it was a high voltage and Bleu up the fuse on the amplifier and damaged the front panel, but I could fix it already, anyway the Clarion 8204R was also damaged, but still no way to fix it, since seems not physic damage only 3 capacitors 2 electrolytic and a ceramic one, I replaced the ceramic one and could have some interference sound, the two electrolytic capacitors seems kind of chubby on top, but seem to be working fine, I will replace them as soon as I can find them, but still no light or a working panel.
Can somebody check out and tell me if has dealt with such situation?
Thanks in advance and best regards.

I will try to add some pictures, so can people check up.

The ceramic capacitor was replaced by a film capacitor (on the green arrow) and the two electrolytic around seem chubby (blue arrows), I will replace them as soon I can find some.

Check backlighting.

Clean and check the ribbon connector that goes to the lcd on the display.

Sometimes these get dirty and/or damaged.

There is a Cleaning spray that you can use to clean it.

Use a multimeter and try to find out if the display is receiving power.

Otherwise it might be a logic error.

Maybe it's something different than being just a capacitor.
