Re: Samsung un60d8000yf - worth diagnosing?

I have a power cord for my ancient Samsung HP-T5044 50" Plasma. What are the chances it would work?

Samsung un60d8000yf - worth diagnosing?

Neighbor's kid got it to fix up and never did. No power cord. Can't tell me what's wrong with it.

I have average troubleshooting (with help) and sdering skills.

Not worth it, right?

Re: HannsG HH241 problems

Agent24, I did as you said and got a reading of 0.03 ohms. See attached.

What else should I check? Or is it probably dead now that we know that the primary fuse is still good?

Re: HannsG HH241 problems

Oops.

Part of the board touched some metal on the frame and made a loud crackle and spark. Now it won't power on. I think I killed it and put it out of its misery.

Re: HannsG HH241 problems

So, to clarify:

1) EVERYTHING should be connected for the first set of pin tests

2) What needs to be connected once the monitor shuts off by itself? I have to disconnect the "high Voltage...

Re: HannsG HH241 problems

The wires I spoke of are circled in yellow.

I'll try again this evening, but from memory, when it was all pulled apart, I had the wires mentioned above connected as well as the "ribbon cable".

Re: HannsG HH241 problems

OKay. This is unexpected.

While I have it taken apart, it has been powered on and working for 15 minutes straight. It usually lasted less than a few minutes when it was put together...

I will...

HannsG HH241 problems

It's been awhile since I tested it, but it seems to me that it would work for a while, then power off.

Here are some screenshots of the capacitors.

Re: Samsung Syncmaster 225BW

Turns out one of the pink wires was coming loose when I put it back together. Seems to be working now. Thanks for all the info, everybody.

Re: Samsung SyncMaster 226BW

Thanks for the advice. I will disassemble it again tonight and check the length of the legs.

Sorry about the post. Mods, please delete these if possible.

Re: Samsung Syncmaster 225BW

I replaced (3) 330 uF and (2) 880 uF caps. I connected it while it was "taken apart" and it worked.

But when I put it back together, the same problems occurred ("analog" for a second, then black)....
