Re: Look at this photo can some one tell me what going on here
I'd first try another video source to be sure which device is faulty.I know that DVR's are famous for electrolytic capacitors to fail.So I change them all and use good quality Low ESR capacitors, plus if the capacitor is say 330UF 10 volt use a 330UF 16 or 25 volt capacitor in its place if possible.Just be sure that the replacements upgraded capacitors can fit the circuit and housing etc before purchasing them.

Re: Look at this photo can some one tell me what going on here
Already try heating the board with hair dryer (cap's ESR goes down with higher temperature)? Looks like artifact due to poor power supply filtering.Never stop learning
