Hi. Had this receiver amp for about 13 years which has always been very reliable. We moved house in the summer and the whole stereo system was in storage for about 3 months. I set it up again last week and now the amp cuts out after about 5 minutes. If you switch on and off it starts again and each time you get a little longer out of it, going up to about 40 mins.
Wondered if you know what the problem might be? Thanks guys.

hi, yes the digital screen is replaceable, but youd have to completely take it apart, and youd have to find a broken one on ebay to scavage for the part. do you have the remote? do you leave it in the same mode mostly? id experiment with the modes, and then keep the remote out the kids hands and maybe put something over the buttons on the receiver to keep the settings from getting changed. you might even just go with the presets like dolby surround or movie mode. right now on ebay, there is 1 and its not broken, so keep an eye on that. the other option would be to buy the working one on ebay and use this one as a sub amp or auxillery for sending music to the rest of the house, lots you could do with it!
Hi mate, had the same problem with my amp.. Take the top off and there is a fan at the back, there are 2 piece's of copper flat wire that touch together and these do not touch anymore so when its turned up or the bass gets stronger it cuts off as the fan should kick in at this point. If you can get these to touch again (bend them) then the problem will be gone!! I have had to do this a few times now though so this is not a long term fix.. I may try soldering!
Ahh technics. Technics always had overheating problems, trust me. Every since they started, their amps would get so hot they would hurt to touch. The reason the fan is not coming on seams to be something inside the circuit board. I'm sure that technics could fix this. If the fan works out of the receiver, then it must not be the fan. ;P
I would maybe get a computer fan, and just put it on top of the receiver and turn it on, or send it in for fixing. Also, do you have to crank the volume to get the speakers to play at your volume, and does the impeadence match the receiver. Because you may be pushing the receiver too hard.
You will need to take the top off and carfully use a air can to blow out all the dust that has accumulated in the back of the tuning knob housing. Then, very carefully spray a very small amount of WD-40 into that housing. Only one or two shots. A SHOT IS A SINGLE BURST - Like the time it takes to blink. Then turn the knob slowly back and forth about 2 times to each end. This should fix it! THanks, Mark
Hi! The problem is, that your SH-AC300 needs an amp with 5.1 input (but no decoder). For this purpose technics delivered SA-AX710. So if you'd like to use your current equipment it would be impossible. The only option is for you to buy 2 more Power Amps (SE-A900S), so that each of 3 amps would take care for one part of music. (one for FL, FR; one for RL, RR; and one for sub and center). Another option is for you to buy SA-AX710. Then all the problems would be solved with it.
