Question about Sanyo HT30744 TV
I have had my set for two years and recently starting having a problem with the sound intermittently when someone walked by the set (old wood floors transmit vibration to set). The problem worsened and now the slightest disruption causes the audio to hum, then sound like loud wind noise on a microphone and finally a pop and the video and audio are both gone. I discovered that the picture and sound can be restored by lifting on the cables for the component input from my DVD player. This led me to believe that I had a bad solder joint on the board from torqing the cables during installation. By the way, the problem remains even if the component input cables are all removed. Upon close inspection, the solder looked intact, but I noticed that Sanyo used only two of the five screw holes they engineered to stabilize the inputs. I soldered the connections at the board even though they looked good and added screws to all of the holes (location for holes is visible on inside of the cover) for more stability. Adding the screws made it much more stable, so I had high hopes. But the he problem remains. Is the problem in the the component connector itself? Am I destined for the repair shop?
That is a dry joint "beat in left side of tv if fail´s its a dry joint for sure"....sorry my english

Yup ya off to the "Shop" me thinks ..lol this type of fault is a nightmare to fix, generally.. any intermittent one is..lol but in saying this any serviceman worth his/her salt should be able to fix it in a hour or two.. I like you would suspect a "Dry Joint" or bad connection.. Make sure you get a firm "Quote" B4 proceeding.. good Luck
