Question about Yamaha RX-V2400 Receiver
The receiver works fine as long as no setting such as Speaker level,stereo to 7 channel/dolby (or vice versa) is not changed. It has happened after a recent lightning strike on satellite tv receiver antenna entered the satellite receiver via the coaxial cable,passed through the RXV2400's body cover and then through the subwoofer output cable in to the subwoofer electronics and thereon to the earthing of the AC supply.At the time of strike,all units were switched off ( Not Standby) still the damage occurred because of lack of earthing,learnt after incurring a great cost! Please suggest remedies.
What if anything have you had replaced/fixed so far? a fairly likely problem is going to be IC (chip) damage in the control electronics, also quite a number of soldered joints could need attention, all components could potentially have been damaged in some way. I mostly suspect it would be a problem in the power supply/conditioning part of the unit, in particular the ground/earth connection from the main control circuit board to the power supply. Also make sure the main power cable of the unit has a good earth still. If you want a bit of help checking this yourself, you will need a multimeter, possibly an ESR meter, a soldering iron and a digital camera. post us a shot or two of the inside and we can hopefully talk you through what to check. An independent ground for this sort of unit is useful and cheap and easy enough to do - please ask again if you want help with this. Hope this helps :)
