Hi guys,
I was going to make a folow-up of my repairs on another thread, but decided to start a new one since I need advice of you all.
So my plasma had the three time blinking problem. I checked the power supply board where the two big capacitors where swollen. I change that and check the board on almost all components, and was confident it was ok to put back in. That was yesterday.
My upper buffer board has two blown chips, but after further review two more pair of ceramic capacitors gave me a bad reading meaning they where blown too. Better off to buy a new board on this part.
So I disconnected my lower buffer board and put the juice in the tv to check my repaired power supply. Everything went ok, blue light and fan goiing, no more blinking. I turn power off and plug in the lower buffer board. Put power back on and see the two pictures below. Lines and colors on the screen. The tv put itself on power save mode (orange light) after two minutes. I tried it three times, same result everytime - power save mode. I turned everything off at this moment to check the three large connections on the left side of the buffer board thinking it could be the problem of those lines in the lower part showing on the tv.
I had before plugging everything back on checked a few ic chips and transistors on the upper and lower YSUS board that people in other thread regarding this Plasma TV and everything seemed to be, again, ok.
Well, after I disconnect and reconnect these three large band connectors and started the tv again to check if it could have been this problem, a familiar cracking sound and smoke came along in the party shop and there I blown my lower buffer board where three ic chips are fu***d. I then got the three blinking lights again. I unplugged the lower Buffer board and still had the blinking lights. I almost put the hammer in. I took a quick glance at the power supply and no problems where showing. I took a beer and got to sleep.
I therefore need the two buffer boards for this TV.
I tried the TV again this morning to check if my power unit is alive, and surprise I have the blue light, blinking is gone so everything seems to be ok on that side.
Everything seems to be pointing at a bas YSUS board. I will disconnect it and check everything on it.
Any pointers on where I should concentrate on this board? A fellow member on this forum pointed me on the upper ysus M662 and lower ysus M672 ic chip but they were ok. I'll recheck them and others.
Thank in advance,
Cheers
