Hi. I am Mike and I have this DVD player and it is a great DVD player but I left it in the rain by accident and now it won't play Movies and it has a line in the middle. This was back in August and it is completely dried out now. I cannot and will not take the DVD to the shop and I will not take it to the shop. So am I screwed or can I get this fixed?

Hi @mikew2025,
Given the length of time that has elapsed since it got wet and that it wasn't cleaned properly as soon as possible after it got wet it may be beyond fixing. Also the battery may be beyond recovery as well but you can only try.
The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the player's operating design and could damage the components. The corrosion starts immediately and is ongoing until it is completely cleaned away
You need to dis-assemble the player, disconnect the battery and clean all the affected parts using Isopropyl Alcohol 99%+ (available at electronics parts stores) to remove all traces of corrosion and water. If possible do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain additives and is not as effective. If you do have to use it check the label to verify the amount of IPA. The higher the percentage of IPA the better
Here is a link that describes the process. Electronics Water Damage
As always with electronics, especially surface mounted pcb be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board. Remove the shields that may be covering some components as the water may have got in under there and corrosion has started. The ends of any flex cables and their connectors need to be cleaned as well
Hopefully after you have done all this and the player might possibly work correctly again.
Here is the ifixit Dynex DX‑PDVD9 Optical Drive Replacement guide that will help to gain access to the motherboard, battery etc.
Most probably you will have to replace the battery so use the information found on the battery to try and find suppliers.
Since you don't want to take it to a repair shop, this is the best that you can try.
这个答案有帮助吗？
Thank you but what about the invisible laser that blinds people and what if I get hurt doing that?
if the device is turned off and you disconnect the power from the device and the battery from the motherboard there's no power for the laser to turn on.
When working on electronics it is always advisable to disconnect all the power to the device as soon as it is accessible e.g. power cord and internal battery (if applicable) to ensure that there is no possibility of electrical damage occurring when using tools etc inside the device.
Mechanical damage e.g. tools slipping, accidentally tearing ribbon cables/plugs etc is a different matter so treat it gently. Also ESD (electrostatic discharge) damage can also occur to sensitive IC components so wearing a wrist strap tied to an earth connection is also advisable.
The only time when power should be on during a repair is if you're fault finding and you need the power on. With devices using laser you just have to be careful and know what you're doing if you need to test with the device open and exposed. In your case you're just trying to clean it and can reassemble it before having to turn it on and see if it works OK or not
Omg! Thanks would a metal nail filer work well enough to open it? I don't have the best tools and I refuse to get new ones.
I think that a metal nail file will be too thick and also that it will cause cosmetic damage to the case.
If you have a guitar pick that may work or even an old plastic credit card perhaps.
If not ifixit has a range of tools that a good for prying open electronic devices - scroll through the list
