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

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

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!

Technika combi unit dvd player wont read discs anymore


how long have you been using this player? I suspect the laser (lens) of the player. I think the laser (lens) is weak that's why it cannot read data/files on DVD discs.

To confirm if actually its a laser problem, insert an Audio CD into the player and see if will play. If it plays, then obviously, your laser (lens) is weak. But if it doesn't play Audio CD, then it might still be the laser (lens) or a mechanism problem.

Get a lens cleaner, use it to clean the lens. If that doesn't solve the problem, get a screw driver, open the player's cover so that you can gain access to the lens, use a cotton board to clean the surface of the lens. This should clean dust or dirt that might be on the lens.

If non of the above solves the problem, then know that you need to replace the laser to a brand new one.

To replace the lens, remove the bad laser, use it as a sample to get exactly the same type and do the replacement. Note that replacing a laser (lens) needs a professional touch, so if you cannot replace the laser, get it to a repairman to fix it for you.

Once this us done, your player will play all DVD discs again.

Does this player still recognize another disc that was not made from it ? of it doesn't recognize and disc at all? if that is teh case that this can be a problem with the lens of the player already you can try to run a DVD cleaner and hopefully that will fix the problem but if still not this may need a lens replacement already...

Dvd won't play my dvd's. keep saying no disc or wrong disc. what is the problem

  • Hi, Sounds like the lens is just really dirty. Go buy a leans cleaner disk and run it through the DVD player two or three times to get the lens good and clean. Repeat about once a month to keep the lens clean and running properly. Sometimes you need to run it through 3 or 4 times to get the lens to read again.

  • These disks I speak of have little bristles on it that "sweep" the lens clean. I use them on all my disk players and they work real well.

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

Regards, Tony

Recently, my Curtis 1053 DVD player has stopped playing DVDs. It attempts to load them, and then says "Bad Disk". I know that the disks are not bad, because they play fine on other DVD players. I...

Over time dust and stuff can accumulate on the lasers that read the discs. You should try a dvd laser cleaner (its different then the disc cleaner you might purchase for a cd player). Its a disc that has a little brush on it. You insert it into the DVD player, you may need to run it 2 or 3 times, but when you use it, the little brush will clean the laser off. Another problem could be that sometimes the laser becomes mis-aligned, inhibiting the DVD players ability to read the discs. I would try the laser cleaner first as the only way to get the laser re-aligned is to take it to a service center and get it repaired. Our old PS2 stopped reading discs and my husband actually took the lid off of it and used a q-tip with some of the laser cleaner that comes with the dvd laser cleaner kit to clean the laser off - we're smokers and pet owners and it was just plain disgusting how dirty that little laser got! After that it ran fine and read all the discs that we thought had some how gone bad.

There are other possiblities too such as a bad laser motor, bad spindle motor (although I think this one is unlikely since you can hear it spinning) and other circuit related issues that can be causing your bad disc error. However these things would need to be diagnosed by an authorized service center.

I would say that as a general rule of thumb, if the cost of repairing exceeds 2/3 of the cost of a new unit, I would just buy a new one.

@Hello - whenever I try to insert a disk to play it starts reading it (display reads READ...READ and then it stops and displays HO7 and won't play the disk at all. I've had the unit a few years but have...

H07 is a common error code for Panasonic DVD players. It means the traverse unit (spindle motor/laser assembly contained in one block) has failed. Usually it is the spindle motor part of this unit which fails first, (i.e. it doesn't spin the disc at all) causing the problem, but sometimes the laser can also fail as well. Because the motor and laser are contained in one device block, the whole part has to be changed, and this can only be done by an authorised service centre. The only trouble with that is the cost. Many DVD drives experience this (different brands giving different error codes) so it's not just confined to Panasonic.

There are only 2 ways to go here; either be prepared to spend a fortune in a workshop service to have the traverse block replaced/aligned (which would include a brand new laser), or simply buy a new player - which would give you a new remote AND an optional extended warranty if available; this would be considerably cheaper than repairing the old one.

Don't be put off from owning Panasonic - they are generally good products.

RCA - Dvd - Video Cd - Cd Mp3 Decoder : Model# - DRC220N Problem - When disk is inserted, it says "Reading Disk". Then says "Incompatible Disk", Then says "No Disk".

Have you already tried to clean the laser pickup lens?

If not, then maybe you should try (there are youtube videos explaining it).

If the unit has been operating for a few years or so and if cleaning the lens doesn't solve anything, then the next most likely problem is the spindle motor which needs to be either cleaned (which is a bit difficult) or replaced (which is either less difficult than cleaning or entirely impossible). The other motor that can cause problems is the slide (laser pickup position) motor, but if the buildup of the disk mechanism makes it impossible to replace the motor(s), then unfortunately the only solution is to replace the entire disk mechanism.

Jvc dvd player no disc error


I did have a similar problem. It was solved by cleaning the laser lenses/prisma. You have to dismantle the whole pick-up the to see the laser lenses.

There is one lens which is held by couple wires and below there is prisma/mirror.

I did use ear-cleaner-stick and desinfection liquid (with alcohol) for cleaning. Now it works!
