I see so many people here with nosound /picture issues:ISSUES:1. If sound main fuse/s are good.2. If no power or standby light check fuse, standby power supply, and look forany signs of damage you can see (burnt parts etc)3. Almost all these SETS troubleshooting consists of checking voltages andtrying to narrow problem down.4. Be safe and if do not know what you are doing do not open set.ANSWERS TO ISSUES:1. RE: fuses---if a blown fuse is found get a good replacement (not the Genericones from like Radio Shack). Many fuses used are special even aside fromamperage. Don't put a higher rate amperage fuse in the set for any reason.2. RE:power supply: if total dead aside from main fuse set uses Standby powerand main power supply (some standby is on separate board but most are combined.Here aside from checking fuses you want to examine all the filter caps to seeif any are puffed up or buldged in some fashion; I attach a photo: top shouldbe (silver metal) perfectly flat and have no brown material coming out on topor bottom---l can give you a description if needed here why they fail---too lowvoltage rating causes them (standby area) to overheat and fail in a average 1-2years= The standby is running 7/24 when set is plugged in.3. Trouble shooting: It consists of the above and then at some point you haveto buy and try a board/s to see which if any fix the issue.4. Safety first---no set is worth getting injured or even killed over.Some additional suggestions:Consider contacting company who made set for information to see if your problemis a common one that their data base has ideas about.Also GOOGLE the model number with either "parts" "problems"or "manual" as a lot of information is available for free.have here only given you the basics but they apply to most sets; depending on your skills if you have specificquestions let me know and I will assist as much as possible.

Ok, I don't have an XBox360 so I can't get specific but if you can't select hdmi input on the TV then you are probably not getting a HDMI signal. I would check your XBox360 set up to be sure that it is set to output video on HDMI not composit, s-video, or component. You might have to return to the last working setup and monitor so that you can see the menu to make the change.

Hope that helps,
