回答“Why my tv has No sound”If you have picture but no sound (1) Press Volume Up Button to check that the volume is at a high enough level. (2) Check all wires to ensure they are firmly connected, including any coaxial cable. (3) Ensure that the audio and video cables are connected to the same inputs on the TV. (4) For example, if the video cables are connected to the Video 1 set of inputs, be sure the audio cables are also connected to the Video 1 set of inputs. (5) If you are using an HDMI cable, see I just installed HDMI cables, and now I have no audio. (6) If available, try replacing the audio cables with a different set. If this resolves the problem, the cables are bad and need to be replaced. (7) If the issue remains, reboot your Spectrum Receiver by unplugging the power cord for 5 to 10 seconds and then plugging it back in. (8) When the time is displayed on the front of the Spectrum Receiver, turn it back on.
回答“How to connect a magsafe to a solar panel”Apple MagSafe Airline Adapter which is capable of attaching to your MBP via MagSafe - but then it's got the DC power connector on the other end. THEN you could connect your MBP to the folding solar power panels. In theory, this could work. I'm not sure since I've never tried it - apparently there isn't anyone on this site who has. There are also other issues surrounding this topic. The solar power panels only provide upwards of 26watts of power - which we all know is insufficient since the MBP needs 85watts of power. Do a search to find one that provides the power output that you need and see if fits your needs. I do know from the very fast search I conducted that these products are expensive! Maybe you could buy a couple of extra batteries to take on the trip with you. Might come out cheaper that way. *Disclaimer* In know way am I attempting to be an expert on this subject. Just merely offering my two cents. Hope this helps.

回答“FoxPro file with a corrupted FPT file”Try opening the .dbf file in Excel or other program that supports opening the .dbf format. Once opened in Excel you should be able to view the file, delete any "bad data", and resave to a new name (with the .dbf extension). Also possible to create a new table with the structure of the old table, append records from the old to the new. May salvage records until the corruption is encountered.
