Dear Yogesh, Bhai andar se wire tut gaya hoga, speaker niche giraya tha kya? Speaker khol ke dekh lo, agar wire tuta hai toh connect karlo. The issue should be with Wires, due to frequent fall or manhandling of Speakers wires get disconnected. You need to open the speaker and check for any loose wires. Please check and let us know.
Overheating can happen due to improve/insufficient air circulation around the PS4. I used to face similar issue, when my PS4 used to remain ON for extended time of period (paused game, downlading or updation). I solved the issue by keeping the PS4 in open and leaving 1-2 feets space between back side and the wall. Now, I use a external mini USB fan, placed on top of PS4 to keep it cool.
Option No. 1 : Try removing your memory stick. The flashing orange light means that the PSP is accessing it (however be corrupted returning an error). Option No. 2 : Try taking the battery out, plug the PSP into the AC adapter, turn it on, and if all goes well plug the battery back in. Wait about 10 minutes with all plugged in then unplug the charger. If the PSP turns off then it is a battery issue. If it wont turn on even with the AC adapter plugged in it is an adapter issue.
Even i faced same issue. One by one all buttons stopped working. Issue is with the conductive film circuit; which wears out and stops working. You need to first open your DS4 and note the model number of Motherboard circuit, based on which you can buy the conductive film from Ali Express or Amazon. Cost of the film is about $2-$4 in ( INR 150-300). You can replace it on your own. Please contact me if you have any query. @tumharajai (InstaGram)
Since you have tried unplugging the device lets try other options. If possible, try replacing the power cable with one from a any other PS4 or PS3 and see if the issue persists when turning the console on. Just to make it sure that your power cable is ok. See if the hard drive is seated properly and isn't damaged to fix the blue light of death (1) Turn off your PS4 completely by holding the power button for at least 7 seconds (2) Once the power indicator has completely shut off, remove the power cable, then all the other cables from your PS4 (3) Slide off the hard disk drive bay cover and check if the internal hard drive is seated properly (4) If possible, unscrew the one screw that is holding the hard drive in place and re-seat it back into its slot. (5) Once you've checked or reseated the drive, put the hard drive bay cover back on, plug all the cables back in and see if the problem persists when turning the console on (6) If possible, check whether the hard drive itself works by setting it into another...
