Hello everyone! I recently bought a used Sanyo DP50747 TV which the owners had for a year and then the picture stopped working for them. They took it to a electronics repair store which said that the “motherboard” would have to be replaced, to quote the previous owners. They were were quoted at $300-800 or so for labour and parts. So I cam along and picked it up for $15 from them and found a used powerboard for under $100 (no such thing as a motherboard), and now need to know if there is anything I should know before opening up the TV and replacing the powerboard. Is it pretty straightforward? Is there a manual I should refer to? Should I do any tests on the parts? Is there anything I should be careful about doing? Anything specific to repairing plasmas, as I’ve never done this before… Any input would be appreciated! P.S. I know this article was posted on iFixIt, but there really wasn’t much there: How do I replace the powerboard on dp50747 plasma tv
Mark, here is the Service Manual and it should give you a better idea of what is involved. As in what to watch out for…..CAPACITORS Good Luck
Mark & Old Turkey, Apparently there is more than one Sanyo DP50747 version because when I contacted Sanyo to see if I could get the power Board LJ44-00132A they asked me for the chasis #. Mark if you still have the board LJ44-00132A & can’t use it I need one for a set I am repairing & no one seems to have one. contact me at jseeaz1@yahoo.com Jeff

OK I have been here before lol. I have replaced all three YSUS and buffers. Plugged in the power and There was a click. LED lights came on but D2. Then they all went off. power supply clicked again then power light went off after 20 sec. What now???????? I unplugged the Ysus board to see if it was the problem. When I do that none of the led’s come on??? I’m so lost!!
