Xr30 g4 burnt capacitors

[ntec]

I have a radion g4 that has several caps that burnt off which is not shown in the pics. Anyone know the exact value of the cap circled in the pics so I can order replacements.

Usually the numbers are on them, take one off and turn it over, but, they may be generic

These caps don't have numbers on them and I don't have a lcr meter to properly check value as I only have a fluke meter.

My lamp is short circuited, when opened i found those capacitors burned, any news?

mg, what makes you think those caps are burned?

I found two burned caps, exactly as the picture, the power supply shut down automatically as soon as I connect the lamp, i removed those two burned caps now the lamp works again without the caps but want to replace them, they are there for something, maybe these caps with the coil produce some frequency for the LEDs, don’t know. i have the equipment to remove one good cap and test, be back soon. Photo attached…

Ok, here my results…

2.3 micro farads

Ok, the top one is burnt. Don't know about the one below it but you could replace them both. You can get them from Digi-key. Search on 2.2uf capacitor. 2.3 is not a standard size. That will get you close, however you will need the correct physical size to fit and the voltage.

Ok, capacitors replaced.... and is alive!!!!

Yes, changed to 2.2 uf ceramic, small ones, just fit inside.

I had two damaged, the one below the burned one on the picture was ok, there is another one at the opposite side of the board that was damaged as well, replaced both, the short circuit was fixed, now seems everything is ok.
