UA-22ES5000 no power - Samsung 22 inch UA-22ES5000 Full HD Multisystem LED TV 110 220 Volts

What makes you think you have defective capacitors?

The led driver AND the T-con board are bad. If you could see a picture with the flashlight then the T-con board would be good. It is not. The led driver can be on the main board or the power supply board. You can get these parts from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

It will most likely go away when you fix the board. I suspect there is a logic system in there looking for that port and is not finding it.

If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

I have the same problem on my 32LN530B-UA. The fuse is still good. I dont see any blown items in the power supply.
Suspecting that this could be a main board problem?

It is most probably the power supply board. There is a repair service for this board available at http://www.coppelltvrepair.com/p/791/lg-42lb1dr-ua-power-supply-board-repair-serivce-for-totally-dead-not-powering-on-or-shutting-down-tv

Be aware that SCMS "prohibited" recordings will trip this flashing light, and will not output. You will have to make an analog copy.

Connect it before powering system. The usual cause of no power on this is improper software configuration or assignment in the PC regarding the sound devices. It is NOT a "fuse" problem.
Make sure that when you go to "Sounds and Devices" in the control panel that the "Voice" tab is shown assigned to the UA-25. If not, make sure it is in the list of devices and assign it as default.

No solution, but I had the same issue with my old laptop, I tried everything, the only thing that worked, was to use a voltage generator, set it to 19.5 V (this was what my laptop was converting to) and getting a laptop power plug and creating a connection. Because the power pack is a SMPS, it was very noisy and this noise would be transferred to the recording.

Question of my own, where did you find drivers for Windows Vista 32 bit? I can only get my UA-1EX to run as speakers, not a recording device!!! HELP!
