Problem for Technics SCEH790 CD Shelf System

Wont turn on




By meanbeanz2 on Oct 18, 2006

" "
the standby red light is on my stereo but there is no display. now when i press the power button to turn it on a low pitched sound comes from the speakers for a second and then the stereo just goes back to standby. i have changed the fuse in the plug but this has had no effect. now i think the speaker wires were loose once when this problem started could this have shorted the system somehow if they touched each other or the system? if so can you think of a solution as i think the warranty is up . a reply would be much appreciated,thanks for your time.

Same Problem

-   Model: KCCD6316DT
My under-cabinet cd radio out of the box did not power up. Purchased my unit from Frys in Las Vegas NV about 6 months ago. Did not open up box until now. Upon trying to power up system, nothing happened. I am out of the store warranty and also out of the 90 day warranty from company. I do not have the receipt (Lost it or misplaced it). What are my options and is it worth the trouble to send it back to the factory? I paid $34.99 plus tax.-   intruser

-   I have a sa-ak320 that suddenly stopped working , with a f-61 code. Now there isn't even a code when I turn it on, I just hear 2 clicks(coming from around the transformer) but it wont do anything, I can't even get my disks out. When it stopped working I had not touched anything from the setup that was working before.-   shocor

-   I have the same problem but there is no hum coming from the system.
The red stand by light stays on the the unit will not power up. No idea what happened. This is a brand new unit and it did this at first start up.-   Guest

You are right the problem is a power supply problem. If it shows F61 then it may be the amp, or the processor, in both cases its not worth the repair

Its too bad this is a solid state system and has no user replaceable parts inside unless you have some knowledge of printed circuit board repairs. It sounds as there may be a power supply problem or the output devices are bad and loading down the power supply. These days, most of these type of systems, do not pay to have them repaired, unless you want to of course. I have found most repairs with the labor are almost or exceed the cost of a new one. Hope this helps. Good Luck

Hi had the same problem with a friend of mine stereo there should be some internal fuses maybe three or four by the transformer. check all three with a multi tester or hold them up to a light to see if they have a break in the wire they some times blow if the speaker wires touch just replace if blown and should be ok hope this helps.... good luck.

i had same problem with my sterio it displayed F61 error and to be honest it was worth reapiring

the total cost of repair was only £120 so for a quite expensive sterio i thought it was worth it
