I have this weird problem with KDL-32EX653: it takes luck to get PMS to find it. When PMS finds it (and it shows in detected media renderers) it works pretty much like a charm. But PMS rarely finds it in the first try, and to solve this I can just quit the program, wait for javaw.exe to close and then restart. Sometimes it works on second try, sometimes it works on 5th time, sometimes it works the 15th time and sometimes I've just too tired to try after 30th time when it still doesn't connect. It doesn't really matter how long the TV has been on (as long as it has already connected itself to LAN, of course).
When I get the program to detect TV, I can even close the TV and if I keep PMS running it won't lose the connection (so if I turn on TV later, I can use PMS without a prob). So the problem would solve by getting it running once and leaving my PC on day and night, but it really isn't an option.
Connection between: TV connected with wire and PC wireless. Router is TP-Link TL-WR841N (with newest firmware). uPNP is Enabled, no advanced options for that.
PC: Windows 7, Asus WL-130N for WLAN.
I really hope that there would be something to try, it's hard to look for info on this since most posts are for a configuration that doesn't work at all. It's really annoying if I happen to have bad luck day. Let me know if you want more specs on configuration.
