Question about Sony DAV-S500 System

2 Answers

Sony DAV S500

DVD player displays "PROTECT" and locks up. It doesn't always happen, but it happens frequently. It happens with Blockbuster, Netflix movies, and even with the DVD cleaner disc.

I have the exact same problem. It started occasionally but now it happens all the time, even without any disc. I didn't try to clean it yet...

Re: Sony DAV S500

The protect indication is because of a fault detected in the amplifier section. If this appeared occasionally before and cleared itself, it suggests bad connections. If you know how to solder, open up the unit and resolder any connections that appear grainy or have rings. That may solve the problem.

I have a Sony DAV S500 AV system and with certain DVD and with the volumn just over 20 (not really that loud), the system shuts down and PROTECT shows in the message window. I read somewhere on the web...

If the subwoofer and other speakers were included with the system, THAT is what they're designed for. Mixing and matching with other products is usually discouraged if not forbidden.

If the problem returns with connection of the sub it may be defective or on its way out. Internal damage to the voice coil from being overdriven could have melted or worn through the insulation and it would cause intermittent undesired electrical contact or load variation under certain conditions, like high volumes.

If your speaker level settings are unusually boosted for the sub you may be overdriving it.

Protect Unplug

I know that almost all new equipment since 99 or so on up has these. They are too sensitive. This is a system program that will put stereo in protect mode when turned up loud or have a lot of bass on to stop from blowing audio outputs.

Sony 5 disc dvd player says c 31 00

C31 usually means a motor error. In your case, it sounds more like the loading sequence is not completing. Can you please confirm that the model is the DAV-FX10 system?

My dvd player (Sony dav s500 system) kept freezing and now always says"disc is dirty" and wont play. Can I connect another dvd player to the system? How would I connect the 6 speaker cables into the new...

Umm, this isn't just a DVD player, It.s an amplifyer too. Just leave the speaker cables alone, plug in the new dvd player into the "video2" jack, yellow cable onlt. Then,plug the audio cables into the video2 jacs (the red and white ones). Select "video2" on the SonyDAVS300 and "video2" on the tv. Insert the dvd into the new player and enjoy. It's screwy but it works through the amp and sends the picture to the tv.

The protect message indicates a problem was found inside the amplifier. The output transistors are most likely shorted and need to be replaced. This is a fairly simple repair and should cost about $40 in parts plus your local labor charge.

Well for the issue of the audio it usually protects when you are approaching the maximum that the internal workings of the system can handle. This also happens when it is overheating. Try to limit your maximum usage of the system to 5-10points below may.

Is Sony DAV-S500 optical input compatible with optical output from Pioneer DVD player DV-566K?

I don't think this has an Optical but a Coaxial connection. You might try a coaxial audio cable not optical.
