My dvd rw.. tsst corp l366c doesn't read dvd disc and it only reads cd disc.. what is the problem of my dvd drive? is there any solution? how?

This unit uses 2 separate laser emitting diodes of 2 separate colours - one for cd (infrared) and one for dvd (red). In your case the diode for the dvd has failed. It cannot be replaced individually so you will have to buy a new DVD-RW unit.

Even after cleaning the unit - it still states that there is no disc in the unit. What can i do?

If you see the disc spinning, but it is taking far too long for the drive to read it, it means the laser assembly has either failed or is failing. If you do not see the disc spinning, then the spindle motor is shot. You can observe the behaviour of the player with the top cover removed; but DO NOT look directly at the laser while doing so; even if it is faulty - it can still emit a radiation beam.

I don't think this would be an economical repair; it could cost more than it's worth for a workshop to replace the faulty parts and align them, plus they might need to upgrade the firmware. It would be cheaper to replace the whole player with a new one.

As products become cheaper to buy new, older models are becoming increasingly expensive to repair.

My DVD player / recorder keeps kicking out the discs I put in. It won't even read them. the screen says close and the tray comes back out almost immediatly. Now it's gotten so bad that the tray won't come...

How old is your DVD recorder/player?
It sounds like it needs a service!
The usual problem with DVD players/recorders not reading discs is that the laser output is starting to fail - and consequently the laser light emitted is insufficient for the system to "read" through the minute "holes" in the disc.
It's possible to have the laser replaced, but this would cost you at least £50, depending on where you live.

Initially, you could try buying (or borrowing) a laser cleaning disc. These cost around £3 to £5 depending on where you buy & live, and have a small brush on the lower side of the disc. Insert this into your player and run the disc for a couple of minutes. If there are any dust particles that have been blocking the light output from your laser head, then this may remove it and might solve the problem.

If this fails, then it seems likely that the laser head is not producing enough output and would have to be replaced with a new one.

Also, you could try playing a CD on your DVD player as these discs contain far less information than a video disc (DVD) and the laser head may be able to cope with this.
If the CD plays ok, then you will know that the reason why it won't play DVD's is the light output has started to fade due to the age or excess use of your system.

Yahoo YHT-400 won't read DVD

I have a Yahoo YHT-400 as well, mine is second hand, but it too has a problem with reading discs, that's why buddy I got it from gave it to me for free, since I only wanted it for a 5.1ch receiver/amp for my computer, so far everything else on it seems to still work. As for purchasing another laser assembly/cradle, probably an individual can't do so, but an electronics repair technician might be able to. And the actual manufacturer is *I think* Diamond Electronics. But I'm not entirely sure why there's two laser pickups in the unit, could be something to do with one of the unit's features that it has. I've opened up a couple other DVD players, and they only had the one laser pickup.

My dvd player keeps reading "Bad Disc" when I know the disc's are ok. It reads this for anything I put in. Is she dead?

first turn off your dvd player and then open it, to open it you should unlock the screws by using screw driver, after you open it, you can see a lens on it, clean it with a soft cotton or a clean cloth. then turn on your dvd and insert a disk, see if it plays a disk, If not, you must adjust the trimmer at the lower portion of the lens, it is connected to a small circuit that is connected also to the lens, you should turn it clockwise but just a little bit.turn on your dvd and cover the lens with both fingers, be sure not to touch the lens, if you cover it, be sure also that you can see the lens, and look closely if it emits a thin red light, which is the color of the laser, if it emits, then your dvd is now ok. turn off your dvd, put the cover case back to its proper place

Good luck, have a nice day ahead

You might try gently cleaning the laser eye with soft dry Q-tip. Other wise the laser will probably need replacing. I repair and sell portable DVD players.

Problem after installing new Lens for LG DVD Player !!

I've been working on DVD players since they were invented, and was factory trained by Sony, Hitachi, and Kenwood, but I must admit, I'm not understanding your question.
The laser diode fires through a lense, that is supended on tiny wires, and moved into focus by an electro-magnet. Now, I have replaced lenses that have popped off due to poor adhesive from the factory, but I have no idea what you mean by "unlocking the lense"
If you mean that you have replaced the entire laser ***'y, and it is not emitting, then that is likely because the shorting bar has not been removed. It protects the laser during shipping and storage, and must be removed. If you compare it to the old laser, you will see pins shorted together by a tiny metal bar, or in some cases just solder...if this is not removed, the laser will not emitt. If you put the old one in and it does, then 99% that is the problem...if the old one does not, then the laser is probably not your problem. Hope this helps, and be careful to always look at the laser at an angle to check for red light, so you aren't performing home laser eye surgery...not a good idea!

P.S. After re-reading your question, on some models, it is possible to replace the lense ***'y, because the electro-magnet has failed in some way, and does not move the lense, but if that is the case, I don't know why the laser would suddenly stop emitting, just because that was changed...normally it is all one ***'y. Good Luck!
