Question about Sony DAV-S500 System

Cant Read Disc

"Sensor unit that reads the Disc". When I try to play a disc it tells me it cannot "Read Disc". I purchased a new part "KHM-240AAA SERVICE ASSY ". When I replaced it with the old part I'm getting nothing out of the system. The disc reader is not even spinning, when I put the old part dack in at least it's spinning but still same error " Not reading Disc". I mail the company I bought the part of, they suggested I reset factory
settings of my DVD?

How do I reset settings or do you think there is a different problem.

I have had a similar problem with new Movie DVDs' - I don't think the DAV-S500 can handle the new Dual Layer DVDs.

I put the DVD in my laptop and it read it straight away with no probs............

Machine doesn't read read games or movies kepts telling us to open disc. or disc is not readable

This can be caused by dirt on the laser lens, or a posible malfunction of it. CD/DVD lenses tend to loose power over time, when that happens, they cant read the discs anymore and you have to get them replaced.
But before you go that way, try cleaning the DVD drive with a disc cleaner, if problem persists, try to purchase a new, and compatible, dvd drive and change it yourself if you can, or take it to repair.

After playing a cd in unit will no longer read DVDs

Had the same symptom. The unit would play CDs but not DVDs. The DVD laser was at fault. Purchased and replaced laser unit KHM-313AHC (ebay- $20) and it now works fine.

HI,. this is a lens assembly fault. the lens is malfunctioning or, it may have stopped reading. this wrong disc code is just a universal warning that is concerning a fault if the main board doesn't receive any data(audio,video) when the disc is inserted.

Due to the integrated status of your unit, this will be a costly repair because, the entire assembly is combined together with the vcr section as well.

You will need to replace the entire assembly to fix this issue. the lens has burned out.

you can confirm my diagnosis by preforming a cleaning of the lens with a cleaning disc. if the unit continues to not read or play a CD after the cleaning, this will confirm my diagnosis.

Please rate and have a great day:)

Most probably YES. Your xbox doesn't detect the disc because the laser can't read it. Either it is damaged or the disc is dirty or scratched. Try several disks, and if the problem persists then you'll know for sure that it's the laser unit.

Wont read discs

If it only does this for this one game, you may have a defective game disc, it happens. Often, if you have just recently purchased it, you can return it to the store and tell them that it was defective and get a new one. If not, you can always try cleaning it though I doubt that's the problem. says "If after reading the above information you are still unable to play a game disc, please call 1-800-255-3700 to discuss available options."
