Soniq PT42SH Plasma has Samsung components inside & no power, no lights & no clicking or sounds when power is plugged in.
It has lots of dust inside but I can't see anything faulty checked some fuses the power board is a Samsung V4C. The previous owner said it just didn't work one day. I have read some old posts but it hasn't helped so far.
If someone could provide somewhere to start please...

Re: IC Number on DPS-286 AP/RDENCA336WJQZ Sharp power board
Hi the C7820 cap measured at 340v
I rechecked the R7914 2.2 Ohm resister again just after I disconnected the power & it showed around 4 ohms one way & nothing the other I left it for a approx 1/2 hour & it was back to 3.5 one way & 2.4 ohm the other way just wondering if I should take it off the board & check it
or is there something else to look at Thanks again
