Question about Panasonic TX-29S90X TV
Hi there. :) I have a 29" TX-29S95Z set, which insists on setting the sound at maximum when you switch on, or when you change channels.(with about 20% THD!) The remote works(all buttons tested on a remote tester), and the OSD show fine. The picture is perfect - it is a sound only issue... You cannot enter the install menu, and you cannot tune any channels. I suspect that either the uCPU or the sound uCPU has got itself confused. The fact that you cannot enter the normal install menu to tune channels also points to the uCPU, but I don't know how I can reset it. Does anyone know how to reset the uCPU's in this model? Is it possible that the EEPROM has become corrupted, and so, is providing false volume settings to the sound uCPU upon power-up? This chassis uses the TDA9875A Sound CPU chip. It looks fine, does not appear to have suffered a static discharge from the tube, but I can't rule that out... Cheers. :) G.
Unplug tv from the power source for about 2 minutes plug in. If this does not solve your problem U may have to futher check starting at the eprom for 5 Volts. also check for bad solders around the area
