How to open case of Acoustimass module

Probable lightning strike killed unit. Is there a fuse inside? How can the case be opened? Removal of two screws does not "loosen" case in any significant way.

    I managed to get the case open following the steps posted by Hatebose. The end of the case slips off towards the side where the cables attach. ie. at 90 degrees to the length of the unit. It needed a stiff dunt to disengage.

    My fuse was OK too so I will have to send the lugging thing in to get fixed.....

Just a bit more info...a bit more detail
Remove the two screws from the case at the back.
Sit the unit in normal upright position. Use a good torch and look at the back of the unit along the top seam where the plastic case joins the main body - there are three latches to disengage along this seam.
1. The thumbwheel which turns to the left & exposes the tab. This disengages a simple Tee'd section on the wheel which stops the case sliding down. As long as you can see the tab this is disengaged.
2 & 3. On the far left & far right of the seam are simple lever latches which must be pushed back towards the main body to allow the rear case to slide down. Push these in then the case will slide down quite easily.

I had the same problem. Remove the "two screws", and also remove the LFE and Bass knobs on the side. There is a thumb latch at the end of the unit opposite the cable connections. You can not see it unless you use a flashlight to look in the seam of the unit. Use a screw driver to turn this until there is a plastic tab sticking out. Slide cover off. Unfortunately my fuse was good and I'll have to send the thing in for repair...

Do as instructed above. Remove the 2 screws and knobs. Put the narrow section where the speakers attach in the back, over the edge of a work bench, with the main speaker body safely on the table. Spin the center tab down, as stated here and when the triangle shows in the middle, you have unlatched the center section. Now put 2 thin bladed screw drivers, on the left and right edges and press them in and toward the thin section (where the cables attach) you will hear or feel them click. NOW take the palm of your hand and pound the thin section that is hanging free DOWN and the back section will slide off allowing it to be removed.

We had a lightning strike close by and now the TV will not turn on. Is it possible that there is a fuse that is blown?

It can't predict what may have wrong with your TV; becuse the lightning stroke will have trillions of volts when it strike the earth. Even its near presence will spoil the power supply section of any equipements. There is surely a fuse inside it, and you can check after opening the TV. Check it first. If it is burned, make a visual check inside the components of the TV for a burned damaged if any. If you find any of it, please do not put an other fuse and make an experiment with the TV. it may cause more components to be damaged. If no visual burned componets are seen, just put a fuse of same ratings [ratings will be either printed on its rims or indicated by colour bands across it]. If the replaced fuse again gets burned as the set is switched ON, make sure that some components in the power supply is shorted, and a through checkup should be done. Contact any experienced service technician to do the work. OK.

Had a lightning strike and the receiver will no longer turn on.

First try plugging the receiver into an outlet that is known to work. If it still does not work, look at the following:

Hopefully there is a fuse on your receiver that is blown. 2 options before it needs to be repaired by a professional:

1. Look on the back for any type of fusing house. It would be labeled "Fuse" and they are commonly held in by what looks to be a flat head screw.
2. If there is no fuse on the back of the unit, it is very possible that there is an internal fuse. Open the chassis, and carefully look for a fuse. It usually is about 1/4"diameter cylinder that is about an inch long. IF you are unfamiliar with electronics, it may be wise to skip the opening of your receiver.

Lightning Strikes can do a lot of damage. Hopefully its a blown fuse.

I had a lightening strike at my home. Since then, the garage door does not function with wall switch or remotes. when i press the switch, light comes ON on the door opener and i hear a click but nothing...

Well, I don't think that disconnecting the garage door from the garage door opener would affect function.

The lightning strike could have destroyed the circuitry inside the garage door opener, seeing that it won't operate with the wall switch or remotes.

It's likely that a board was fried by the lightning which would render the garage door inoperable.

Following a direct lightning strike to our pole transformer, transformer blown ,, replaced ,, several electronics not working including our Bose Wave Radio (no CD) ... Where can we find repair and how much...

Bose does not release their schematic diagrams or parts lists, so factory maintenance is about the only way to go. You can start the process by visiting, but be ready for some sticker shock. Before you do anything though, every Bose has a line fuse inside the case. The location varies by model and date of manufacture, but if you open the case it will be simple to locate. Check it, and replace it if necessary. The fuse is there to safeguard electronics against power surges, so it is your likely culprit.

My fridge was damage by high voltage of electricity is doesn't switch on at all ,Model sv2118si 660 litre Sumsung


When you say that your fridge/ white goods appliance was damaged by high voltage, we need to exactly what the voltage source was that did the deed.

If you are talking about a bigger voltage input source, from the mains suupply, then it is likely you would have had a fuse within the plug that would have blown. This should be the first thing you will check regardless of the voltage.

If however, you are telling me that your house took an in-direct or worse still a direct whack from a lightning strike, then my dear friend you have quite possibly a totally deceased appliance. For a start, such a strike could melt your plug and possibly socket. The fuse inside the plug wouldnt be a relevant factor here; because if the lightning made it from the sky to the ground, I am sure it can cross a 40mm gap within a plug. Then the lightning surge would simply travel up the power cord, knock out your gas pump, stepdown transformer and any lights or motors within the appliance. The cost of changing every part here is not worth it. You would be better off claiming on insurance or simply buying new.

there are a few ways you can investigate what has caused this, and possibly cure the fault, unless it is a lightning strike of course that is responsibe.

The first thing to do here is dismantle the mains electricity plug that is attached to the fridge. Check the small fuse inside this to see if it is functioning. You can do this in many ways. The best I find is to get a multimeter or the appropriate tester and perform a continuity test. See this link below

If the fuse is broken, then change it and repeat the test; YOU MUST replace the fuse with what the original one from the manufacturer was.

If the fuse is working, then your fault is elsewhere and you will need to perform the above tests on various components relevant to your fridge.

The worst case scenarioo is the lightning strike; and in order to identify this, you will need to do one or two simple things.

Firstly, head to your main consumer unit (fusebox) and check that all of the fuses are in the "closed" or "on" position. Open fuses indicate a power surge or a short circuuit somewhere on your supply, but relevant to your fridge. RCD circuit breakers all narrow down the searching to one localised area. You should also do this test for identification of original fault.. The same for when you as above check your main fuses.

If the fuses on the consumer unit are "open", then either replace them if you have to, or you simply either push them back in or move them to the "closed" position. Also check that the consumer unit is not damaged in any way, as you would expect from having too much electricity put through it. Fire damage, warping, blackening, discoluration, bent or broken components are all good indicators of this.

Another test you may have to do, is simply look around your house. Has anything else been effected. If it has, then it is likely that it was a lightning strike or something equally as damaging, if no, then it could simply have been a power surge that only really effected your fridge. Even so, is any of your other electronic and white goods items behaving oddly? TV menu keeps appearing or going into standby? Is the lights on your DVD player behaving erratic or does discs keep being ejected at atrange times? What about your computer or laptop; do these strangely start playing up? If so, then either the lightning strike is to blame or you have had a powersurge.

Once you have done theseinvestigations please let me know the outcome and if it is negative, Iwill gladly advise you further.

I look forward to hearing from you soon and hopethis is the fixya for you;

Yours sincerely

TX-SR803 with no sound or popping hissing on any input

It is common for a short term power surge to open up the internal fuse in the main power transformer. Without testing some components inside the unit, I really can't say for sure whether or not the unit is worth repair. I would suggest that you invest in a detailed repair estimate at an authorized Onkyo service center.

Keep us posted.
