Re: SCEPTRE U550CV 2.5v standby... (should be 5)
The board is fully disconnected from TV when I checked 5VSB (same for that reference board).
Caps look fine visually but I haven't desoldered any of then to check

More info:
Obviously - the power supply doesn't work. No standby light on TV, it doesn't turn on. The pin is 5VSB and it has 2.5v on it. Fluctuates between 2.3-2.6.
Also, I've bought a similar PS (from different Scepter TV model). Similar enough to use it for reference measurements (same pins) -...Last edited by dentheman; 08-09-2018, 12:53 PM.

SCEPTRE U550CV 2.5v standby... (should be 5)
All components look OK (nothing burned or leaked). The STB measures around 2.5v instead of 5... Any suggestions? Thanks
