Hello, I have a Sony Bravia KDL-46EX400 and after an incident the HDMI ports doesn't work anymore. I have checked the other ports (D-Sub / AV / Component) and they work OK, even the USB can reproduce 1080p content. One curious thing is that although the HDMI ports are not showing any image (or sound), the TV recognizes the port in which is connected the Playstation 3. The incident, in case you need to know it was caused by a contact between the Antenna in and the TV cable. The TV cable was never connected to the TV before, due to a system incompatibility with PAL-N signals. The case is that they get in contact accidentally and that did cause a few sparks in that area, after that, the TV starts with this problem of not recognizing any HDMI signals. I made it work the first day by unplugged it and plugged it back, but it only work that time. I can replace by myself any of the boards inside, but I don't know if this problem is caused by the A board itself or it could be other thing. Well, any suggestion about where I could check for probable failures are welcome. I don't have warrantee for this TV now, and there is no official service around (at least not closer than 100 kilometers), that's why I'm asking for your help. Thanks
