I have a Samsung HT-TZ212 DVD player with a burnt out resistor (SMR60) on the PSU board, can anyone tell me the value of this component as it's impossible to read it.

I didn't see that part location on the schematic. Parts list leaves ALL location numbers blank for some reason. See for yourself:

There may be several components need replacing among bulged caps(if any). Common problem with those series power supply and there was a service bulletin which is linked in that forum. Use Google translate to see the information posted here; (French)

Thanks for your help, that was very useful...I now know the value of SMR60 (470ohms) and the modification which involves adding a load resistor (220ohms) at the discharge line of the D5V, between the jumper wire? and SMR46.
