Question about Samsung Televison & Video
HPT5054X/XAA, blank screen, audio works. No bulging capacitors on any boards. Vs should be 230V, measures 12.2mV; Va should be 63V, measures 63V. How trouble shoot the power supply board? If replace it, how now if Y-sustain board is good? Other ideas?
A capacitor can still be bad even if it is not visual. basic tests can be done with a multimeter, only an ESR meter can truly test them. You would need to know the pin out to know where to check, but I would assume you are going to have various voltages exiting the board. Your two measurements don't add up if you aren't reading any voltage.

SOURCE: p50hdtv10a y-sustain and pcb
I had this problem with a different brand plasma and it turned out to be cracked or missing solder on the power board lead to y sustain. I removed the power board, desoldered the connection, clean it up and then resoldered the connection. Everything works great now.

It's not the x main. 90% of the time it's a y buffer that goes out. It's usually the top buffer. 3/4 of the time the buffer takes out the y main board too. You cannot just replace the y-main or buffer because it will just burn out the other within seconds. Also about 1/4 of the time it'll take out the top transformer on the power supply too. The solution? First disconnect the power to the y main board. turn on the television and check the voltages coming off of it. Careful it's high voltage 208V! Remember it's DC too. Then disconnect the buffers from the y main board. You can try powering the y-main up to see if the little LED lights up. This does not indicate it's working though but it'll tell you if it is possible to fix. The fixes for these boards is only for electronics guys. It usually involves replacing 1-3 capacitors and 1-4 FET's. Since a bad buffer can take out a good y main in seconds it's usually recommended that one replace all 3 boards at the same time. It's a $250 fix. How do I know all this? I've now repaired 5 of these televisions. I owned one and spent close to 600 repairing it. I bought misc parts and broken sets online for months before I had 2 different repair guys walk me through the process of repairing them. I had so much cash tied up in parts that I bought 3 more dead sets and repaired them to justify all my spending. I've never had an x board fail. I've had EVERY top buffer fail. I've had all but 1 y-mains fail. and 1 lower buffer fail. I've also had the y buffer fry it's top chip, blow a capacitor and FET on the y-main, and fry the top transformer on the power supply before my eyes. It only took 5 seconds. Replacement of the 3 y boards will almost always fix the sound but no picture problem. Hope this helps!

7 blinks Driver SOS 2 SU / SD / SS Boards
(SC floating voltage area)
This is the fault indication meant by 7 blinks of standby light. Just visit this site 'Electro-help' Faults with plasma TVs are described in detail. Check this link and select the site. Pull up older posts there.

if no voltage out either a short on the line pulling it down or its at the source--usually one or the other.

Tips for a great answer:
Feb 01, 2015 | Samsung HPT5054 50-Inch Plasma HDTV
Apr 02, 2013 | Samsung PS42P2S 42 in. Plasma Television
Jun 20, 2012 | JVC LT-32E488 32 in. LCD Television
has been discontinued. It can be purchased used for $40-$60.
Now, the good... There is a replacement that Samsung "says" works just fine. That board is BN44-00162A. That one is going to run around $150 for a new one.
