    Can the lens assembly be repaired and if so is there a part I can purchase to replace the old assembly or does it have to be sent to a repair shop. Is it worth repairing or buying a new player? nko

    Thanks for your assistance. I think I'll take the easy way out and purchase another player. Thanks again. nko

HI. most disk error message are given if the player lens is unable to read the actual media that is inserted due to major surface scratches.

If the media at hand is completely free of any surface scratches and, the discs you are using are compatible with your player, this could be a more serious issue concerning the lens assembly. You can confirm this by unplugging this unit form the wall socket or surge protector for 5 minutes. After the unit has been unplugged for five minutes, simply plug it back into the power source and power up. if you get the same error after this hard reset, it will confirm a major lens assembly malfunction. the lens may have failed and cannot read or scan anymore due to this failure or, it can be that the entire assembly and control board has failed as well.

In most cases, its the lens assembly that will be the issue here and not the main mother circuit board. if you have anymore question, feel free to ask. i will be standing by..

    HI. unfortunately, this particular assembly is not available in repair shops and it will have to be sent to a sponsored repair depot for this repair. The typical assembly transplant will cost 120-190, plus shipping and tax as well.

    Im my opinion, i think you will save more of your money by just purchasing another fresh unit. the actual replacement of this assembly may be more expensive than a entirely new unit.

    I will confirm the availability of this part and report back shortly.

    OK, i checked on the lens assembly and, it is not available for consumer purchase. the only part that is available is the deck assembly and it doesn't include the actual lens assembly. the lens assembly will have to be repaired by the manufacturer.

How to remove disc error message for my lg ht303su-a2 dvd cd player because it plays some dvds and other dvds wont play


Check a CD. If it plays, the Optical Pickup for the DVD is worn out and will need to be replaced.
If you are interested in having your LG repaired, please look to my website at audioserviceclinic.com. Thank you.

Lg dp 781 is saying no cd when there is a cd in it and then sometimes it says disc error. we have played the cd's that are in it a million times before. help


Look closely, with lots if light and magnifying glass, at the pickup lense. Static attracts teeny tiny fibers and they bend the light and cause read errors. Also, smoking covers lense sometimes. Can be cleaned with rubbing alcohol and swab. I think that cd cleaning disks cannot actually clean as the lense is recessed.

DVD plays audio but no video? The LG screens comes on but the screen goes dark and only the audio plays. I ran the disc cleaner.


NO NEED TO CLEAN LENS, YOU HAVE A MOTOR PROBLEM, IN THIS CASE YOU WILL BE ONLY ABLE TO PLAY AUDIO DISK AND NOT DVD. BECAUSE OF FREQUENTLY USED, DVD DISK MORE SPEED ROTATION THEN NORMAL CD, SO CHANGE YOUR MOTOR AND CHECK IT WILL WORK......

Disc Error when I try to play a dvd LG DP781


Hi,

Sounds like either a dirty or weak laser/lens. Pls try cleaning with a CD disc cleaner or manually using cotton buds (if the eye is accessible).

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Stops Playing: screen freezes


My friend suggested I clean the dvd optical reader lens inside the player with a fine brush (like a camera brush with a blower bulb). This seemed to help immensely. I'm not certain if this is just a temporary fix, but it seems to be ok so far.
