Question about LG LST-3510A DVD Player/Receiver

1 Answer

I think my laser is fried. Can I fix it?

I have had my unit 3 years. It has run pretty good. Today it stopped reading disks. I opened it up to clean it off and found no buildup at all. However, it appears that the black plastic cover over the laser has an irregular opening. I am thinking it should be round and it is not. I also have noted that the surface of lens is a little cloudy. Any suggestions. I am pretty good on electronics, but I do not know if I need to replace the whole laser or just the lens. And what are the issues in doing so. Any help would be appreciated. LPOp1234

Yes you will have to replace the whole assembly, but before doing so, try to clean it (the lens) first with a dry clean soft cotton swab or buds. do not put any cleaning agent on it. you may use also a compressed air (duster) to blow accumulated dust iside the assembly. sometimes the mirror (reflecting mirror) under the lens which directing the lazer is also dirty that needs to be clean and the only way to reach it is by means of that duster. good luck!

Have had this item now for about 8 years and very happy, today after one cd played it desided to stop playing cd's, all I get is " no disk ", I have put disks in all 5 drews still no disk in...


You can try to open the unit and clean the cd laser with a Q-tip and some rubbing alcohol. Unplug unit and find the laser be carefull not to press ******* the laser eye you can also try to use a camera bulb that you squeeze to blow air on the laser as there could be a speck of dust on the lens this may work its worth a try. If the cd still is not picking up then the laser or the buffing board maybe bad! Give it a try hope this helps good luck.

My playstation 3 has stopped reading disks. could i purchase the part to fix it or is there any place that could fix that problem. when i bought the ps3 i only had the one year warrenty on it from sony,...


This is quite typical of a failure of the laser lens and is very common on the PS3 unfortunately.

The only solution is to replace the laser. If the unit is out of warranty Sony will charge $150 to repair it. However if you are reasonably handy you can buy a replacement laser from around $30 and do it yourself. Ebay is a good source for these replacement lasers. Make sure you order the correct part as there are a few different versions used depending on when your Ps3 was made. You will need to open the unit and check the part no on the laser prior to ordering if you decide to do this.


More information on how to do this repair including exact video footage to demonstrate the procedure is here

I would rate it as a simple to medium level of skill required. No soldering involved.

Thanks for using Fixya.

Turns on does not read any discs


This error is caused because of your PS3 lens. It's probably dirty because of a long period from dust build up. So to fix this problem, it's high likely that you need to open up your console and fix it from within, but how?
Well, in order to fix an error like this, you can do 2 things. You either send your console over to Sony, or you will actually fix the problem all by yourself. But, what's the best option to do?

Leser Cleaning: This laser is super sensitive. Do not touch it with your finger or anything that could potentially damage it or leave a mark.
1) Canned Air. Get a can with a mini straw and blow it out pretty good. If it's giving you problems, blow out the ventallation ports as well.
2) Disc Cleaner. Best buy makes a disc cleaner that looks like a DVD. This is not the best way to go but it might work. Ask an employee what they recommend using.
3) Q-tip. If you have already opened it; or are past waranty and desperate to get it cleaned, open up the console and with a Q-tip dipped in a very small amount of rubbing alcohol (make sure it's not wet, just damp) SUPER LIGHTLY give the laser one good rub.
Please make sure you're giving it a good means of ventallation and ensure to never put it on carpet.

Xbox 360 console can't read disk


If your console has stopped reading discs this can be because the receptors on the back of the drive have overheated and to fix it you will need to send it in or use a good repair guide to do the job.

Hi there my 360 is having some problems,when i put a game in it keeps on telling me to insert the disk into an xbox 360, or if the auto run option is off,then it will just say play dvd or open tray? after...


after taking the entire drive apart i found that the laser / moter assembly was offset. this ment that the disk was tilted 1degree towards the laser and intern hittng the laser assembly that so many peopl think is "laser burn" which actualy is the disk physically hitting the laser. how u fix this is as easy as adjusting two screws were the moter and the laser/ tray assembly meat. now thses arnt nomal phillips, flat head or torx scews. i found that stickin a drill bit in the screw head annd turnin it with some pliers did the trick. this fixes the open tray error for good unless the disk is causing it. IF anyone gets open tray ocasionally this should stop it for good. also try cleaning inside of drive make sure connection to drive is good. try turning the system on then emmidiatly opening and closing the tray a couple time.

Literally just happened to me as well


helps gamers, please stop copying and pasting answers to questions. Anyways, I've said this in other similar questions on Fixya. But the main reason this happens is because of the certain disk drive. From my experience, the problems mostly lie within the Benq drive. You can find which drive you have without dismantling your xbox here.

I hope this helps.

Aiwa 3 disk CX-NMT 70 MODEL SPINS A FEW TIMES ON EACH DISC..wont play at all..What can I do? Thanks!!


This can be fixed by adjusting the POT on the rear side of the laser. My Aiwa had the same issue and there is an orange screw on the rear of the laser. Turn it about 1/16 - 1/8 turn COUNTER clockwise.

Please understand, this is a temporary fix, and will eventually ruin your laser mechanism completely. The company is out of business and the unit is 10 years old, so I didn't much care...perhaps I will run across a CD assembly I can replace it with, but this is a temporary fix for this issue.
