Samsung HP-S5053 Y-SUS

[dbier63]

Hello I tried experimenting with a picture issue I had and now I have 4 blinks on the set. I removed one of the Y-SUS connectors (the one with the X on it) that go to the panel and put it back on while the set was on. Needless to say I got a pop and now I have the 4 blink problem. Can anyone please help to tell me what I may have done. PS board relay clicks on and then off blue light on front blinks 4 times and goes out. Green led on small board above main board stays solid.
Any help is greatly appreciated.
Thanks.

Ok never ever mess with a y sustain cable or any of the cables going to the panel while the TV is on. Not only is it dangerous but it can cause significant damage to the TV. What you probably have done Is shorted out that buffer board. You can attempt to disconnect that buffer board from the TV and what I mean by that is pull the buffer board completely off the Y sustain board and unplug all the cables then power up the TV and see if you have half of a picture still. If so replace the buffer board. if not you have other significant damage to the Ysus along with a failed buffer board.

What exactly was the picture issue you had that you were experiencing before you pulled the cable and try reconnecting it with power on?

The lines are vertical colored lines? Like from top to bottom? If so that is panel failure as the vertical row Drivers located at the bottom of the panel Are starting to go bad. Unfortunately this is not repairable. Did you try disconnecting that buffer bored and seeing if you still have a picture On half of the TV still?

Unplugged buffer and left ysus in still no boot up. 4 blinks and nothing.
Also yes thin colored line runs from top to bottom

Plug the Ymain back in. Turn all the lights in the room off and close the blinds. Tuen the Tv on does the screen glow at all ?

4 blinks is also not an error code ! Its the normal boot up sequence for Samsung Tvs.

There is no power going to the screen. I hear relay clicking but screen does not come on. All this happened after I reinstalled a lifted cable back to the buffer board while the power was on. There was an arc and then I pulled the plug. I've checked all the fuses and they are all good. Something is blown either on the power supply board or somewhere because power is no longer switching on to the to the buffer boards.
Any ideas are greatly appreciated.

Looks like I blew a couple diodes on the lower section of the lower buffer board.

If them diodes are blown you will have some shorted fets as well.
