The machine needs to know certain information about the dics and what it contains - if it can not find this, it can not proceed. It could be for several reasons. 1) The disc is the wrong media type. 2) The area containing information about the contents of the disc is damaged - scratched disc, etc. 3) The disc driver mechanism is not functioning correctly 4) The optical reader system is not functioning correctly
Try another disc from a reliable source, for example, a commercially produced DVD. You could clean the optics and also check for any obvious damage to the mechanical parts, including cleaning away any extraneous dust, dirt, etc. The problem is that if it requires parts, they will be on level with the cost of a replacement DVD player. I can purchase a good quality model for about the cost of one or two DVDs at my local hypermarket.

Re: the screen shows invallid disc
If the unit is more than a year then you must have a worn laser pickup. this are low cost units (some call it disposable type) having the defective parts replaced is not practical as you may spend i guess more than 50 % of the new unit cost.
You can also try cleaning the laser lens using cottons buds rubbing it gently on circular motion! it could help the lens to read clearly and may work again but it wont be for long thouh...
This is your best answer: Coby's marketing plan places priority only on a low purchase price. This player has broken, plain and simple, and will cost far more to repair than to replace.
Out-of-warranty consumer electronics are almost never repairable, due to the high cost of both labor and of factory replacement parts. In fact, certain manufacturers are known to sell replacement parts at inflated prices in order to discourage repairs and encourage new product sales.
When you replace this player, consider total cost of ownership ahead of just purchase price.

Re: the screen shows invallid disc
I agree with SUPER8, if the lens has been cleaned then it could be the pickup laser or its associative circuitry. The problem is the cost of repair sometimes is equal to the cost of just replacing the defective unit. Let me show you, these costs are based on my shop fees, which are based on the typical market fee:
Standard DVD/DVR/CDROM/VCR Player/Recorder
$00.00 - Estimate
$30.00 - Schematic Fee 40% of Estimate- Starter Service Fee*
$60.00 - Per Hour Labor
$??.?? + $50.00(Shipping) - Parts $70.00 - Travel Fee
This breaks out as follows:
$30.00 (service documentation) + $180.00 (Labor standard 2 hours troubleshooting + 1hour repair) + $99.00 ($49.00 Laser pickup assembly) + $50.00 shipping + $70.00 Travel Fee Total $379.00 of which 40% is due before the work can begin.
So as you see the cost of $379.00 puts you at the cost of a new unit or at least close to that of one.

If your DVD player shows no disc, even a disc is inserted, try to clean its laser head assembly, by inserting a cleaning disc in it and play atleast three times. Take it ejected each time before you play it. If it does not helps, open the top cover of your DVD player, insert a disc, and notice if the disc spins or not. If disc spins, and not reads, the laser picup unit of your DVD player is faulty, and should be replaced with same type and number. If its stripe wire connected between pickup unit and main board is detachable, try repalcing the strip wire first. In some occations, bad strip wire will show this type of problem.
If disc does not spins, the sled motor [the motor that used to spin the disc at high speed], is damaged and shoud replace it. OK.
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.
Did you make the disk if you made the disk your computer has to give it a digital signature so the DVD player can read it if you're using a regular DVD then I would very carefully using rubbing alcohol and Q tip clean the actual laser I would be very careful doing this if too much rubbing alcohol is on the Q tip it will ruin the laser you can also try resetting the DVD player by taking out the battery and unplugging it from any power source and leave it that way for at least 20 seconds to a minute if that doesn't work you might have something else wrong
With the power turned off, open the DVD Player, and then open the top where you load the DVD into the player. Locate the laser lens and notice that the laser is attached to a transport assembly that moves the laser diagonally outward in a slot. 1. Slide this assembly outward to the end of its track. 2. Slide the assembly back inward to the closest inward position. 3. Repeat the process of sliding the assembly outward and then back inward.4. Put in a music CD and let it play all the way through. This helps to calibrate the laser head assembly movement. When the music CD is finished playing. 5. Put in a DVD, and you should have a working unit again This is a factory solution from Mintek that was given to a customer who ask for help with the forever loading disc problems. This solution may work on other models of portable DVD players. Most portable DVD players use this type of transport mechanism. Try this solution it might work for you. I hope this information helps you with your problem.
Hi.... Very lightly clean the laser lens ( looks like a very small eyepiece) with 91% or better alcohol on a swab. Then very lightly dry it off. Also..have you tried another DVD or CD in it? Check for dust or debris in where the laser pickup is
The laser or pickup has failed or is out of alignment. That symptom is caused by either a dead motor, or a bad laser. The only thing you can MAYBE check is that there is no dirt or grease on the lens. If it is clean it is time for a new unit.
Sounds like a common problem with this trutech brand. There are some possibilities. 1. Laser could be worn out, 2 it could be a bad cable coming from the laser. 3 The home switch for the laser to come all the way back to its "HOME" position could be bad. But usually if this is the case, the disc won't spin at all. And 4th, the spindle motor that spins the disc could be worn out. Causing the disc not to spin fast enough and thus causing an error. Let me know if you want to send me one of these anyone so as i can trouble shoot the problem further. Keep me posted and i hope this helps you out some. Thank you Jay
