Oh dear, more bulged Samwhas! Just pulled these from a 40" Samsung LCD. Actually, although there were three bulged (two 1000µF 25V pictured, one 470µF 10V not pictured), only one of them tested really bad (~4 ohm ESR.) The others tested 0.2 - 0.5 ohms or so each, which is still failed but not as bad. So, I suspect the 4 ohm one went out first, and took out the other two. That would point to a QC issue, which makes me suspicious of Samwha caps.
After replacing them (with Panasonic and Nichicon), TV works fine now. (Before, it had difficulty powering up from standby, stuck with flashing LED.) Oh, and TV is about 18 months old, and really nice with 1080p, USB and 100 Hz, so Samsung cheap out on even their nice TVs. My main TV now.
This brings the number of Samwhas I have replaced to 22.
