Ptid-8940nr. Why does it turn on and the lights start flashing, then it turns off?

since you tried to by-pass security may have done more damage to a simply worn key problem

Going in and out sounds like the antenna cable got loose, but the not turning on sounds like the fuse blew. Worth checking those 2 things out first and foremost.

Do you still have your owner's manual? If not:

Make sure the red wire is going to a voltage source that turns off when the key is off.

Hello,

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.

Good luck.

hey i have the same problem did you ever get yours to work if so how did you get it to work ??????????

check the owners manual for the stereo and see what file system format you need to use on the flash drive i know i had the same problem when i changed radios worked on my old one but plugged into the new stereo wouldnt load had to unload the music and reformat the flash drive and then reload the music onto it that took care of the problem. where you have tried two different usb drives would say not likely you have bad drives

i have Power Acoustik PTID-4007 my problem is not turn on lcd not out audio but yes is take cd and out cd, the screen is move in three postion. help me please
thanks

you are better off setting your deck speakers amp to a high pass filter setting on the amp. Adjust gains to increase desired bass and clarity. Turn off loud button if you have one, that will distort your deck speakers.

Check the wiring!
