Question about Technics SC-DV290 System

2 Answers

No sound i have the technics SC-DV290 stereo but cannot get sound, it plays for about 20 seconds then cuts off, i have tried playin tapes also still with no sound. I have read some of the problems other ppl have had so it may be the same problem, how much do you think it would cost to have this fixed? Technics SH-DV290 cannot get any sound - repairer says two main processors are cold - therefore not working - wants a lot of pennies to repair same!

Hi I think this is a thermal protection problem.
Firstly disconnect all speakers, now make sure there is no small wirers shorting the speaker terminals, If this is ok reconnect the speaker wires making sure you dont short the connections.
Next thing to do is th check the output fuses, firstly make sure you have disconnected the device from the mains power as you may get a shock and death may result , once you have removed the unit from the power socker you can proceede with removing the top cover, you should find two fuses next each other it may be a good idea to rfplace both fuses also it would be a good time to clean out the chase and pcb's with a duster and a vacuum cleaner try not to damage any thing.
Once you have dne this put it back together and good luck.

Hi let me tell you that you technics if it plays for period of time then blocks usually this problem lead with auto protection before you really burn it.......firs check all the wires well connected to speakers,check each speaker with a baterry it will pop up...if you do all above i wish you luck... if the problem is most serius needs a resoldering action or even change something overheated components. take it for qualified professional and the cost may vary where you live....... saludos

How do i connect technics turntable model SL-QD33 to technics stereo model SC-DV290 and what do i need to switch to on stereo to play records.


Have a look on the back input panel of the sc-dv290. Check for a "PHONO" input. If there is no phono input it will not play turntable. If there is: then plug it the turntable in and switch the SC-DV290 to PHONO mode.
Another way would be to purchase a "phono preamplifier" from ebay: Hook the turntable into the phono preamplifier, and the preamplifer into the SC-DV290 AUX input.

Technics SA-DV290 Amp. Sound cuts out as volume is increased


hello it sound like the output ic may be in trouble you may have just dry joint on the ic which just resolder it . or there could be a capacitor leaking or they may have swelled up in which you will have to replace. it's best to do some visual checks first i'e look for any burnt parts any capacitor with bulging tops

Technics DVD Stereo SC-DV290


never done this myself, but I would guess you take phono jacks from your TV (L & R out) and plug them into the back of the sound processor, iether VDP(AUX) or VCR(EXT) IN
then go to your remote and press (vcr(ext)/vdp(aux) repeat pressing until you hear you tv
each time you press button it should go through a selector menu
TUNER->DVD->TAPE>VCR(EXT)->VDP(AUX)

hope this helps

System stops playing


Hi Big Belchie

Sounds a bit like it is overheating. It is in a cabinet? Check that cooling vents on top and sides of the unit are not getting obstructed. hehehe sometimes parties are responsible for those piles of cd covers that block off the vents. How hot does it feel when it stops working?
