Question about Sony SLV-D550P DVD Player/VCR
This unit was working fine, then one day it started not reading dvds. the dvd's spin, stop, and the display reads ERROR. i tried different ones to make sure it wasn't the disc. i opened the unit up, took a Q-tip and lightly cleaned the lens. this did not fix the problem. is it possible that moisture got underneath the lens? do you have any suggestions how to fix this? i really like this unit.

If you have necessary tools and test instruments, know safety precaution in basic troubleshooting try the steps below to solve your problem.
Assuming that the disc is good.
1.Clean the lens. - Sometimes because of dust and any fine foreign objects the optical lens can't read any disc. If you have a DVD Lens cleaner, play it to the unit. If this is not available you may manually clean the optical lens. Open the cover and gently clean the eye of the lens by smooth,clean,soft cotton buds. Be careful while doing this, just a gentle stroke only.
2.Check the ribbon - Check the ribbon connected to the lens from the main board for scratch, damage. Once it has an open line then of course the lens can't read the disc, this is because of the movement of the optical lens back-and-forth. Also try to erase the contact by pencil eraser. If you've done the steps above and the symptoms still there then the next step requires you a little knowledge in soldering technique and reading the ohmmeter.
3.Check the spindle motor - Check the spindle motor that spin the disc with an ohmmeter. You can test it using the ohmmeter (x1) even it is connected on the lens assembly.Good motor - reading should be fairly high and it will spin. Bad motor- reading will drop to low resistance and will not spin.

Hint : Most of my repaired unit the above parts are commonly caused of the problem.
If you confirmed that you have a defective motor then replace it with a new one. Before replacing the new motor you have to check the clearance of the disc holder with the old one. The clearance should be the same as the old because if not the lens will not read the disc if it is too far or too close.
If the above steps didn't cure the problem, high chance that your optical lens was faulty.
you can't do the job yourself, I would advice you to look for a professional to
troubleshoot the symptom.
check if your unit is under warranty period, avail it because the manufacturer
will fix it for free. Don't attempt to open the cover(it will void the
