Open sonos play 5


Okay, so I literally just took mine apart, a screw came out that was holding the subwoofer in place and it was causing horrible distortion and vibration.

First off there are a bunch of screws you need to remove, all phillips heads thank god. The front grill just needs a little bit of tender pulling, start at the seams on the sides and pry it out, its only held in there by some velcro material on the front and how tight the sides slide into the rest of the unit, so it shouldnt be too hard to remove. Once it's off you will see all of the screws that need to be pulled out, they are all the same length and there should be 6 of them.

After that you will need to flip the Play 5 upside down and pull off the rubber bottom plate, its held on with a tacky adhesive but its pretty easy to pull off. You will see that there are now a bunch more screws to undo at this point, including 2 stickers over two of the screws saying if you remove or break you void the warranty (Sonos warranty is 1 year, so if it's beyond that, go for it). You pull off those screws as well, pretty sure there are 6 of one size and 2 of a skinnier size. This will easily remove the bottom plate.

From there you can now access a few more screws that will then allow you into the system. I hope that this can help you fix it or you got brave and tried it yourself at this point.

How to dismantle panasonic sc-hc3 sliding door?


Remove the speaker covers by sliding a screwdriver carefully under the edges and push it up. They are just pressed into holes. Once removed, you have to remove the 4 screws of the top cover (the one with the buttons). After removing the screws slide a screwdriver carefully under the top cover and push it up. Attention, the cover is connected to the body with little cables so do not break them. Once pushed up , you see little screws that hold the top sliding rail. Remove them and you can take the sliding door off. Good luck

Open the case


The top plate is held on with four pieces of double-back foam tape applied to four press fit plastic discs and one piece of double-back tape along the top surface immediately behind the display. The discs are located 1/2" in from the sides and 1-1/4" and 4-5/8" from the rear (as measured from the "nose" (rounded edge)) of the case.

To open the case you'll have to carefully pry the top up enough at one side to get a razor blade under to start cutting the tape at each plastic disc. Once the foam is cut through each disc, the top on that side will be loose. Do the same to the other side so that both sides are loose. Now that the sides are free, carefully and slowly lift the top at the display-side rear so that it hinges at the tape behind the display. This will break the tape's bond and the top will come off.

The top is rather stiff and so if you're not careful you could bend it. The plastic discs have ringed shafts that press fit into holes and may even start pulling out of their holes if you're lucky, but that seems remote from what I experienced.

Again, use care in prying and make sure that you cut through the foam. Then, if you're lucky enough to solve the problem that lead you to open the thing, then you can use double-back tape to hold the top in place or if you're mechanically inclined, you can drill top and tap the plastic discs for screws so that you can open it easily whenever the mood strikes you.

How do I clean my blu ray player?


Hi, Music and game discs collect dust and dirt on their surfaces overtime. This build-up can interfere with the sound and performance of both discs and the player system. Cleaning fluids and cloths will aid in keeping a Blu-ray discs clean, but to clean the lens of the player, some dissembling is required. Below are instructions on how to open up a Blu-ray player and clean the lens on the inside.

Instructions



Things You'll Need:

* Blu-ray player
* Screwdriver
* Lens cleaner
* Cotton swab



Turn Blu-ray player over and remove the edge screws holding the bottom plate onto the drive using a small Philip's head screwdriver. These screws are located opposite each other on the bottom edge and one has a metal piece attached. Remember to reattach the metal piece when replacing screws later.


Remove the bottom two edge screws located near the center of the base and the three screws holding the base plate at the opposite edge from the screws in step 1. Again, one of the edge screws will have a metal piece that goes back in place later.


Extract the motherboard connectors. Once the screws are out, simply lift the lid and pull out the connector. The cable remains connected to the motherboard.


Remove the motherboard by lifting it and turning it to the right to pull out the cable connection. Do not yank the cable out. Grip the end plug firmly to release the cable.


Turn the player back over the right way and remove top cover to unscrew the four sides and one top screw holding the lens cover in place. The lens cover moves to the right so lens is accessible for cleaning.


Use cotton swab dipped in a little lens cleaner and clean the lens using a circular motion. Dry the lens using same motion with other end of the cotton swab.


Reassemble machine by reversing these steps.

The system is playing DVD but no sound produced,still when i try to change function i.e from Dvd to either AUX, BAND,or USB its not changing but all other remote control keys are functioning.


As for the sound, there are some players that has different volume controls for each speaker, so check the volume of the speaker through your remote.

Or maybe the sound I.C of the player is bad.

You might just loose the Player with a screw driver and you may probably see what's wrong with it and if you don't, couple it back and put it on, don't be surprised to see your player working properly.

My Samsung player hung such that no button functions. What I did was just to loose it and clean the inside and by the time I coupled it back, it started working perfectly up till now.

Note that this could only work if the player is not having any major fault.

I wish you the best.

Unlocking Disc Tray?


If you want to remove the entire tray, remove the top of the casing and the the front as well. The front is held on by a screw on top and two smaller screws, one on each side. Then remove this face plate by releasing the clips built into the unit, two on each side, two on top, and two bigger ones on the bottom. Try to just lay the face plate/front cover down beside the unit to avoid the effort of disconnecting the other pieces. Remove the two screws, one on each side, of the dvd laser top cover. Remove the two screws under that, one on each side, they're also accessible without removing the dvd laser top cover at all, but either way all four screws need to be removed. Remove the center screw holding the top of the tray/turntable. Then remove the turntable top, you'll have to pry this up near the dvd laser while sliding it around to get it past the two interlocks(inch wide lip overhanging) built into the tray bottom. This may not be necessary to remove, but it makes it easier to slide the tray out later. Next remove the two screws holding the tray mounting brackets in place, there is one located on each side near the front. You may only have good access to one side and should remove it first to give yourself more room to work on the tighter side. You may even be able to pull the tray out without removing that side's screw and bracket at all. The tray should slide out of the front then, like it does when it opens during normal operation. At least put the top cover to the dvd laser back on, and if you're wanting to reattach the top of the turntable, remember to do that first...before attaching the dvd laser cover. There may be one or more screws somewhere I didn't mention to remove, it's been awhile since I took one apart. And of course, don't look at the dvd laser and don't mess with the two 250v capacitors...they will still be charged and can shock you. They'll look like two black cylinders, side by side, each about the size of a C battery or a little smaller. Most likely you should be fine unless you remove the power supply board and make contact with the soldering points on the underside. Just try not to slip the screw driver and so forth. Hope this helps, it's about all I could remember, so look for other attachments, screws, etc if you get stuck.

DVD load / eject problem


This is a solution to all those who have either a DVD which does not load and which cannot be ejected and also to those who have the system stuck in MP3 mode. The solution is the same for both problems. Unfortunately due to the design of the HTS6510 it’s not a simple job but if you are methodical and take your time then most people should be able to do it.
 
 I personally think the problem stems from dust building up on the laser. I noticed that the extraction fan at the back of the unit draws air, partly, in from the front slot and over the DVD and (Sony) laser.
 
Anyway I’ll talk you through what I did but please be aware that this is not a screw by screw, connector by connector account.
 
You’ll need a small torx screwdriver (the unit is put together almost exclusively with a single torx screw size),  a very small Phillips screwdriver and a pair of snipe nosed pliers. Also a couple of small bowls to hold the screws in will be a good idea.
 
Firstly make sure the unit is disconnected from the mains. Then begin by undoing  the four torx screws at the back of the unit which are holding the cover on. Then remove the silver plastic side sections by sliding them towards the back of the unit. Under these you’ll see two more torx screws to be removed on each side. Remove these and you can then remove the top cover.
 
90f4437.jpg

Have a look at the first attached picture. You should see the same thing with the lid off the box. I’ve labelled all of the assemblies up. There are four circuit boards which are arranged two on the top and two underneath these. You will be removing the top two (Audio amplifier board and the power supply board).
 
The aim of the game is to move the front section (the bit with all the control buttons on) away from the main section so that you can get access the to the DVD housing (this is the player unit where your DVD is housed). The front section is attached to the main section by four plastic clips (the plastic barb to metal slot type). Two are accessed from the base of the unit and more on each side. Don’t unclip these yet because the circuit boards are attached by ribbon cables which attach to the front of the unit . It is these ribbon cables which must be disconnected before the front can be unclipped and access can be got to the DVD unit. There are also a couple of bonding leads which attach the front of the unit to the ain chassis. These have small spade (push on) connectors and are very simple to remove.
 
You don’t need to disconnect all of the ribbon cables – just enough for you to be able to swing the front of the player out of the way.  Make sure you mark any connectors which you disconnect in some way so you remember where they connect to when you re-assemble the unit. I used a permanent marker to put a series of dots on the ribbon end of the connector and board end of the connector. (i.e. one dot on each denotes a pair, the next pair has two dots etc etc.)
 
Some of the leads which you will need to disconnect are attached to the two processor  boards which sit below the two uppermost circuit boards. Gain access to these by removing the four screws (one on each corner) holding the power supply board onto its mounting (there is also a nylon support in the middle of the board – squeeze it with a small pair of pliers to release the board).
 
Next remove the black plastic insulator sheet below the board. With this board removed, the metal shelf which the Audio amplifier board is attached to can now be removed. Note that some of the screws on the external back of the unit will also need to be removed before you can do this. You don’t need to take the audio amplifier board off the shelf – just remove the shelf and audio  amplifier board together.

5acffa2.jpg 

You should now have an assembly which looks like my second picture. As with the top two boards unplug the connectors on the boards to allow the front section of the dvd player to be moved away from the main part of the system. Again don’t forget to mark the connectors so you know how to re-connect them.
 
If you have got this far you are doing very well!  I then undid the four screws holding the dvd housing and unshipped the entire housing, but with hindsight this wasn’t necessary. There are four Phillips screws holding the top cover of the DVD housing on. Remove these with your Phillips screwdriver and lift off the lid.
 
You can now remove the DVD / CD. At the same time carefully remove any dust which has accumulated in the DVD housing. Take care not to damage the delicate lens or its assembly. I used a dry cotton bud but a blast of dry air or a lens cleaning brush would be an even better choice.
 
Once the dust is removed refit the cover the DVD housing and assembly is basically a reversal of the dismantling. Once its all back together switch on and they system will be back to normal. If it doesn’t switch on – open it up and recheck your connectors – most likely one of them isn’t properly engaged.

Control and amplification circuit boards are not recieving power


If there are no visable ways to get into the box from the back then you must remove the speaker from the from and gain access through the hole the speaker came out of. It is not too uncommon for speaker units to built this way. Good luck.

Sc-HT80 Problem


Hi one solution to your probelom is that the lazer is underpowered.here is a fix it 4 u. A major problem began 2 years ago Some New DVDs would not always play. Message on LED display says "NO PLAY". I discovered today that the problem lies with the laser being underpowered for some DVDs. On the web I found a fix. Warning! Always have someone competent with electricity to fix the SA-HT80 with the following instructions: 1. Remove all disks from player. 2. When door is open slide front door cover upwards to remove. 3. Leave door open. 4. Important UNPLUG FROM THE MAINS! 5. Remove the 3 screws from under the front panel then remove cover screws. 6. Disconnect player from the mains. Remove cover. 7. Once you have removed the cover you will see on left side is the drive parts. 8. Pull out the two flat cables which go to the Drive from the vertical circuit Board(Hold the cable with thumb and forefinger close to the connector and slide the flat cables out of their connector. 9. Remove the screws fixing the drive unit to the base of the cabinet. 10. Now remove drive unit. 11. Placing the drive upright on a flat surface proceed to remove the two screws holding the Plastic bridge that sits over the disk. 12. Also undo the screw on the small circuit board which holds the disk sensor switch onto the bridge and unclip that small board. Remove this plastic bridge over the drive. 13. On underside of drive remove the two small screws from the drive circuit board. You can now gently prize this board loose.(There is some resistance as a plastic clasp is holing onto the underside.) 14. Turn Drive back to upright position. 15. Remove the screws which hold the drive in(Screws go through rubber mounts to cushion the drive). 16. Once you have loosened the drive look at the underside and you will see one flat cable goes to the Laser. Where this cable meets the metal part you will see a tiny device connected on the outside edge of the flat cable. 17. Turn the POT 1/5 off a turn clockwise(looks like a small washer and be gentle with it) I used pointed nose pliers for this. 18. Now reassemble DVD player. 19. Ensure cover is in place and screwed down before connecting to a power supply. This is a guide which you will follow at your own risk. Happy fixing Gerald
