Dune Duo multimedia player Power supply

[smic717394]

Hi,

I need a bit of help. I have a Dune Duo, The psu has the fuse blown, maybe the bridge rectifier as well, but the problem is that the ic controller is damage so I cant read the markings. Anybody can help me identify the chip. This power supply is used in allot of dune boxes. If anybody can take a picture of the psu so I can identify the chip I would be grateful. Or where Can I get another PSU.

Thank you.

the missing piece is in the unit or on that board - shake them over a table

The whole problem is because of this glue!

I can´t find it. its somewhere in another dimension by now. I remove the IC, I thought that maybe on the other side would be some markings, but no luck it just some generic number I think something like L04 02

you think it died because of the glue? I can replace the fuse and the bridge rectifier, but unless I change this, I don't think would do much good. Would be a shame to throw away a perfectly otherwise working unit because of one compontent.

It is more likely that the small electrolytic cap next to the ic is bad. Post a clear picture of the bottom of the board as well as a clear view of the trace side under the ic.

Thank you. I´ll try it there. For now I bought a power supply board module 12v 6A and its working fine, get a little hot, but its ok so far.
