Technics SCEH790 Stereo, DVD problem

I have had this stereo (with DVD player) about 3 years, and recently the DVD player has been coming up with 'NO DISC' when I try and play DVDs, it whirrs a couple of times and then just displays 'NO DISC' after about 10 seconds This problem occurs no matter what disc slot I use (it is a 5 disc changer). I've tried leaving it a while, turning on and off. leaving off for a couple of days then trying, and even giving it a bit of a blow in case any dust was in front of the laser Any advice? Or does anyone know where I could potentially get a replacement unit that would be identical in appearance and not look out of place in the middle of the stack? Thanks

    thanks a lot electro, is it worth giving it a blast with an air cannister or is this more likely to dislodge the laser eye etc ?

    god only knows where i'll find someone to take at look at this, think I ordered it off a .com site and definately outside the warranty :(

    cheers techman, luckily I havnt had a chance to blast any air into it yet (I dont think that me blowing into did would've done much damage!) so will opening it up carefully and giving it a light rub

I too had this problem, the laser had become stuck,a gentle clean with a q tip did just the job.

It's probably just the laser eye. I's have a pro take a look at it, shouldn't be too complicated to fix.

Im sorry man i gotta step into this!! Never ever go and send a Blast of air into a lens assy. it can not only ruin the sensitive membrain that holds the lens assy in place it can also knock the assy out of alighnment.. If you need to clean a laser lens assy you need to go into the unit with a small non q tip type device as a shammy cloth works fine and lightly clean the surface of the lens only if you tryed to use a lens cleaner before. but using a blast of air is the wrong thing to do man!!!!!!!!!

I need help connecting the Technics SCEH790 dvd player to my tv. i only have scart outputs in my daewoo dty-28a8gbs tv. theres a 3 prong scart attatchment at the front but no audio connection. am i still...

Hi, If you say there are three connectors on front of t.v. those sound a lot like " FRONT A/V " inputs, which are abbreviations for audio/video. one of the connectors should be for video( possibly colored yellow ) the other two should be the audio ( red and white ) To check if this is the case connect rca cables from the back of dvd player video and audio out's to these connectors. Then change the input on the t.v. using the remotes "INPUT " button or it may be called " T.V./VIDEO" if no remote use the button on t.v. that says A/V and stop when you get to " FRONT A/V " or there may be a label on front above those connectors calling it vcr 2 or 3. if that's the case use this input when it comes up on t.v.'s screen. Thanks for choosing FixYa, I hope we have been of service and good luck, Prodzilla

Hi my technics hifi is playing up, it turns on but the stereo sound processor will not come on.this needs to work for the hifi to work can you help

hi mate, the sound processer has packed up, mines done exactly the same thing, i've taken it in to a panasonic technics specialist and the verdict is just that. i've confirmed it by swapping the sound processor with one off a friends stereo and mine came back to life. Hope that helps mate.

Switching on by itself

Try covering the little red window that has the wireless remote receiver behind it. See what happens.If the problem quits,your stereo is picking up some other IR source in the room.
Also,shoot some WD40 into the cutout around the power switch
( WITH THE POWER UNPLUGGED) push the switch on/off several times then plug the AC back in.
