Reverse polarised an lcd controller and blew capacitor

euser1984

I put a 12v power supply in but mixed the poles up by mistake....

I soldered a new capacitor in today and it still doesn't turn on even though nothing else has any appearance of damage.....I thought that the capacitor may have taken all the damage......

The capacitor blown is the one beside the dc jack....25v 220uf

The 5 - legged thing just above it is probably a regulator - test around there

For the cost of it not really worth fixing / chancing though in case it fails in the future and takes out your LCD panel

I get 12v out of one of the regulator pins and that's all - the rest have no reading....

I crossed the 4th and 5th a little by mistake and a light came on on the power button board....but a little spark came from the regulator.....that 12v is still there though....

Can I rule out the capacitor as being a part of the problem now?
