Question about Panasonic sa-ht800V Home Theater Audio System SA-HT800V System

NO DISC message


The DVD worked fine a few days ago. Today I put in a DVD and got a NO DISC message. I've tried 3 different DVD's and the same message. 
I've had this home theater for about 4 years and its worked fine up until now.

My other components (speakers SB-FS803, SB-PC803, SB-WA312) are fine. If I can't fix the receiver, can I purchase any other receiver that can use these speakers?

    Yes, thank you. I am interested in any receiver that I can use with my current speakers (SB-FS803, SB-PC803, SB-WA312).

    THANK YOU.

Hi,

The first thing i would suggest you to do is a hard reset by unpluging the the player for 30min and then try again.

If this does not solve your problem then please see if the player tries to read the disc.
Load a disc and listen.Does the player make squealing noises or is it totally quiet? Squealing noises may indicate that the player is trying to synchronize with the disc but can't due to an obstruction on the lens or in the laser path inside the pickup or a defect in the pickup. This can also be caused by an intermittent signal problem due to a faulty ribbon cable.

Totally silent means that the photo sensor is not getting any usable input from the laser at all, meaning that the pickup is "blind" for lack of a better word.
This can be caused by an obstruction of the beam by foreign matter on the lens or inside the pickup all the way to a marginal or failed laser diode and/or photosensor array. This can also be caused by a bad ribbon cable with one or more severed traces.

You could try to clean the optics. This is the most common malfunction as far as i know in all disc players. It would involve taking the cover off and finding a way to expose the lense, and then cleaning it with a very gentle brush. some players have a cover for the lense that swings to the side during playing, this greatly reduces the chance of dust accumulating, but its still worth the try.

If you actually see dust on the lense, then its just that simple. clean, close, play.

It may also be worth your while to check on the small shafting that guides the carriage of the laser pickup. Dirt, grome, dust and solidified lubricant can cause stoppage of the carriage and the laser eye then fails to read the next track.

If the problem does not get solved then you have to get it repaired.

Goodluck,

Hello

It's possible the lens is dirty, this can be fixed with a DVD / CD lens cleaner disk.

its also possible the lens is damaged and would need to be replaced.

I'd first try a dvd lens cleaner.

    That may bring the player back to life. If not, then it may have an optic failure occurring or needs a new spindle motor. MOst speakers are interchangeable with other systems. BUT these days, packaged systems are often the go. Are you looking for some reccommendations for what to get next?

    Looks like this type of combined receiver dvd/vcr player has been surpased somewhat. These days, DVD record functions are popular, but they mostly dont have power amps built in, that means a bit more expence with an additional amp to power the lot up.

    Check a few for your self here

Open up the unit and clean the lens using a cotton swab and alcohol. If that does not resolve the problem, try a music CD and report the results here. I suspect that the optics have begun to fail. If that is the case, the music CD will play but a DVD will not. The optics assembly is available (part # RAF3023A-1) for about $60.

First try turning off the unit and unplugging for 15 seconds to reset. Next try a different DVD. If nothing works then you will probably need a professional to service the DVD drive.

I assume that problem is dirt on laser lenses. If you don’t get any result after this, than you can replace receiver with new one. If you want to use your existing speakers with new receiver with integrated amplifier, you must pay attention on wattage, to be same like old one (i.e. 100W), and also resistance (i.e. 4 ohm). If it’s same like old receiver, you should have no problem. Good luck.

Bose 321 DVD System


I love my Bose 321 DVD system, but a few days ago, it started acting weird. I put in a DVD, and it reads - "No Disc".....and I'm not sure why. I cleaned the disc, and I also played a DVD/CD Maintenance kit - I'm not sure what is wrong. It seems like I have a problem within the system - what can I do?

No disc message on DVD Player


What you might want to try before giving up would be to get a lens cleaning disc. If that does not work then you may have to take off the top, locate where the small laser lens is, and with a small cotton swab, soak slightly in alcohol, and in a swirling motion, clean the laser lens, now with the dry end, do the same. Wait a few minutes for all the residue to dry. Plug in the unit, and see if you made any differance. If you did GREAT!!. If not well at least you tryed, and there is not alot more you can do as a consumer, without test equipment, or speacial jigs. It most likly will not be worth taking into a repair shop, as these days these players are almost a dime a dozen!. Good Luck Ps Please do not forget to rate this.
