Need help fixing Samsung Slimfit tx-s2783

[Bowlsnapper]

I will have to replace the film caps in order to test the B+ voltage. Is it safe to assume that the film caps are not the culprit? Should I just leave them alone? I don't even know how to convert microfarads to nanofarads.. I guess just 1 into 1000. Not a huge deal. But I can't even find replacements for these caps anyway. The 615nf measurement freaks me out. I can find .56uf 400v film caps on digikey, but that's it. Somebody here is saying it 62000uf. There's no way. Should I just leave these alone? I'm suspicious of the nearby transistor that's supposed to handle B+.

Zeno: Every single electrolytic capacitor was just replaced, so it can't be that. Soldering is sound. 130v is indeed marked on the underside of the board. So I should test it while plugged in? Where should I attach ground, chassis? If it's too high then a component has no continuity, and if it's low then it's basically shorting, correct? Also... Which contact is the 130? I can't quite pinpoint it... I guess I can just move around with the meter, until I'm sure I've found it. It can't be THAT far off...

The problem with my measurements is, I can't find replacements that match what I'm reading. The only way to get accurate replacements is by purchasing the service manual, the way I see it. But the film caps are probably fine. I believe my issue is elsewhere...

Should I give some of these solder points a good reflow?

130 VDC apx while set is on.
Caps are in mfd, or pf. Asian sets use nano at times. Also US uses mmf
at times, same as pf. Should be tons of sites explaining the conversions.
Its been 10 yrs since I opened a set so I dont want to give you bad info.
Before that it was 40 yrs of use & second nature. But age has
effected the memory !
Keep in mind this set has 2 grounds. Hot ground is the primary of the
power supply. The rest of the set is ( cold ) isolated. Use the CRT
ground or tuner shield for this one. There will be different ground symbols
in the manual.

I'll have to research what mfd is. I'm new to real electronics and working on CRTs. Please forgive me. As far as I know, mfd is not a searchable parameter on parts websites, so I would have to search by capacitance. Thank you for recommending a grounding point to measure the 130v/B+ with. I will put it back together and attempt to do so safely. I wish I had somebody here basically holding my hand and letting me know what is the right thing to do.
