Hello everyone. looking to get some help on a bit of troubleshooting on a dead Samsung. It has the infamous no turn on just clicking going for it.
TV is apart and I have started to trouble shoot. 1st thing was I verified all the fuses are good.
The next thing I did was tried to disconnect the x and y boards individually to see if the tv turned on. No luck there either. Unplugged the y board, clicky clicky, no turn on. reconnected the y board, discoed the X board and same thing, click click click... no turn on.
At this point, with all the boards connected I checked voltages out of the power supply. Output to the X, Y, Logic and A/V contrl Boards were all constant at 15.14, 15.13, 5.15, 5.4 volts DC no mater how bad the relays were clicking. The voltages that were way off were the Va and Vs. Va should have been at 55. I was only able to measure 32. Vs was suppose to measure 202, i was only getting 92. The other strange thing was that the power supply was clicking in a set pattern of 5 cycles then it would take an 8 sec break and start over. each time it clicked in the 5 part cycle the voltage grew a little with the Va and Vs, but never reaching what it should be.
Va would be 29, 30, 31, 31, 32 while Vs would be 80, 87, 90, 91, 92 then the cycle would stop for about 8 seconds and repeat all over again.
My question is, is this enough trouble shooting to say it's a bad power supply or are there other things that need to be done to draw that conclusion? I'd like to fix the TV without throwing money at parts it doesn't need.
Thank you in advance for any and all help you can provide me.
