Re: Speaker grill

How do you get behind the speaker grill. The speaker is located in front of a large piece of wood. Do you have an instructional manual for replacing protective screens on this type of model?

Thanks.

No power of my SC-HC3


I have good and bad news for you. If you have a UK power plug for 250VAC (odd shaped three-pronger), then you should be able replace the small 5 Amp fuse inside the plug (jack) head of the power cord and it will work just fine. That's the good news. If your like the rest of us on the planet, then there is no fuse to protect the power supply from line voltage spikes. Some component of the power supply has been fried... there is no internal fuse as I torn the thing apart, including the transformer compartment looking. Rumors elsewhere talking about an internal fuse in the SC-HC series of Panasonic CD/IPOD players are not true. I had read several myself and believed them to be true, so proceeded with dis-assembly. THERE ARE NO USER SERVICEABLE PARTS INSIDE THESE PRODUCTS. It is not worth repairing. I am an engineer and can tell you that the best thing you can do is salvage the speakers with the grills and make yourself a nice pair of cube bookshelf speakers with them. A pair of 1500Hz crossovers (or thereabouts) and a a pair of screw-in speaker terminal strips from Radio Shack, carpenter's wood glue, wires (red & black by convention), a low-wattage soldering iron, electronics solder, and some planed wood is necessary. The original design is tuned port, bass reflex so to obtain the same sound quality you will need to cut a round hole with an Area of 17.7 cm2 in the speaker box cabinet back. For those using inches, it's 2.54 cm/inch; divide by (2.54)x2, so you can understand the port hole is not very large. You should place the port hole on the back as in the Panasonic design as making the speaker cabinet larger will require a different port size to get the optimum 50Hz tuned bass punch from the speakers. Just cut the wood to form a rectangular cube. Make holes in the front precisely so the speaker grills can clip in around the speakers, make your tuned port hole in the back, and make a small hole to pass wires from the crossover inside to the speaker terminal strip on the outside ON THE BACK (usually near the bottom). You will need to use a hole saw (cheapest type uses an electric drill attachment) or a jig saw to cut holes into the front of the speaker box to insert your speakers flush against the wood face (make a paper template and trace the round circles onto the wood). Connect each speaker to the proper part of the crossover; i.e., tweeter and woofer cone with your wires and solder all the connections, finally, screw the speakers into the fronts with wood screws. Use carpenter's glue to glue the wood pieces together. If you have the time and the inclination, this makes a great family project to introduce recycling concepts too. These speakers will be good for surround sound applications (rated at 40W RMS) or simply used to connect to a small sound system. To use it with a PC, you will need to buy an a stereo mini JACK and carefully solder the wires you extend from the speaker terminals: join the two black wires together (one from each speaker black terminal) to solder onto the long side inside the stereo mini JACK and solder each of the red wires onto a separate prong of the two remaining. This will provide stereo sound by inserting into a PC's headphone plug. For information on how to design and build speaker cabinets, Radio Shack has an excellent (very cheap) paperback on the subject. Hopefully, this gave someone an idea.

REMOVE speaker grill off tv?


The front speaker grill on the WS-55613 will be one of two types

!) if it is a single plastic piece with gray cloth all the way across beneath the screen--it pulls out---held in by plastic pegs--start at right or left side and pull it free.

2) some versions have two smaller grills--one on either side---they pull out and this type has a wood plate (usually black) held in with four or more screws---you remove the two small grills by pulling them out and to get the inspection plate off you remove the screws holding it.

Let me know if you have questions.

The volume goes up & down by itseal


I have had some real experience with the Mitsubishi sets.....fixed hundreds of them.

There is something easy you can check out to see if your problem is what I suspect it may be.

The front keyboard with all the buttons on these sets has tiny "micro" switches---sometimes one will go bad and instead of having to push it--it closes by itself--seen about 20 of their sets with these bad.

If the set has a large speaker grill on the front it should pull out---held in with pegs---some models have two smaller grills on either side and a wood like black piece in the middle.

Remove the speaker grill and you will find an inspection plate of masonite behind it--usually 4 or 6 screws secure it in place.

The idea here is to get the inspection plate off---You will see one or two sets of wires coming down from the front keyboard---follow them to the right and unplug both (usually two plugs). THE PLUGS WILL BOTH BE DIFFERENT WITH LETTERS ID THEM--SO YOU CANNOT MIX THEM UP.

The set will still turn on using the remote--if you do not have the problem with this done--you have at least one bad micro switch.

If set works fine you have two choices---Use it with the plugs disconnected with the remote.

OR

Someone would have to in most cases remove the entire front screen assembly to get at the micro switches for repair/replace.

This problem is common enough that I carry an assortment of original switches with me when I repair sets in someones home.

Let me know if you have questions or need advice--I am here to help people.

Ic location


they are located in the front of the TV behind the speaker grille. Remove the screws from behind that secure the speaker grille and the two inside the small door below the control buttons, Then you will see a small access panel remove that and the ICs are on the skinny board up front. Do not remove the rear panel on your model with the cord plugged in or it will destroy the HD circuits

Focus not sharp


Yes, you can adjust the focus of the CRTs without causing other issues if you exercise some care in the process. There are two types of focus adjustments in your TV, electrical and optical. The electrical focus is more likely to change over time than the optical focus. That's because the optical focus is mechanical and would likely only need adjusting in the event of a CRT replacement. The electrical focus controls are located behind the front speaker grill and the front access panel. Pioneer TVs will either have pop-on/off connectors where all you need do is grab and pull, or it may have a few philips screws securing the grill. The screws are generally hidden behind the plastic molding strips just above the grill assy. (they are snap on/ pull off) There will be a small, black control assembly located behind the access panel. There will be 3 focus controls and 3 screen controls. The screen controls adjust the intensity of each CRTs brightness.

Good luck!

Removing front and back speakers in 1991 Grand Am....


There is a lot involved in replacing these speakers. You should also know that the original factory speakers are 10 ohm speakers. This means that if you replace them with new speakers (most of which are 4 ohm) you run the risk of damaging the stereo, the speakers, or both. This can also cause a potential fire hazard in your car. If you want new speakers, you really should look at installing a new stereo as well.

To get to the back speakers, you will need to remove 2 bolts located under the front edge of the rear seat (bottom). After you remove the bottom, you will need to remove the rear seat (back). This involves removing the bolts that hold down the rear seat belts, which is a large sized torx bit (T-45, T-47, or T-50... Don't remember which). After removing these, lift straight up on the seat back to remove. Now remove the deck brake light housing, and the bracket that holds it. Now the deck cover can be removed. Be careful not to bend it too much getting it out from under the side trim on both sides.

For the front speakers, you must disassemble a good portion of the dash. Remove the screw holding the light switch and the wiper switch housings. This screw is underneath each housing. Once removed, there are dash mounting screws behind them. These screws (and many of the other dash screws) are a smaller torx-bit (T-10 or T-15, don't remember which). Sometimes they use a 7mm bolt. There is a cover panel just above the glove box. This panel is held on with 2 screws located in the glove box. After removing this panel, you will find 2 or 3 bolts holding on the dash. Last but not least, you will find 2 bolts inside each of the defroster vent grilles. These grilles just snap out for easier access to the bolts.

I Bought The Wrong Speaker Size!!!!


You have to cut out a large enough hole in your door to fit the speakers. But you have to keep in mind if your factory speaker came with a grill your new speaker will have to have one too. It will make it look better. As far as fit, you have to make sure the depth of the speakers are compatible with the window mechanism, or else you will have real problems when you go to roll down your window. Measure the depth of the stock speakers, and when they are removed, roll down your window to see if your new speaker will catch on anything. It may have the correct depth, but the diameter of the new speaker magnet/cage may be too large. If it fits, you are in luck. Get a handy saw/sheet metal cutters and make your hole big enough to fit. If you do not have enough room you will have to have a spacer added where your speakers will mount. A spacer on the outside of the door with the speakers mounted on top of it will work. Wood would be the cheapest route, using a solid piece and painted to match your color scheme. If you use the spacer, you may not have to cut on your door. If you want to get fancy, you can cover the wood in fiberglass cloth and resin to make some nice custom speaker mounts.

Help with lines in screen


At the bottom of the speaker grill there are two holes filled with a plastic plug. Use a small flat head screw driver on the sides of the plug to slide the plugs out. You'll see the little space next to the plug on either side that you can put the flat head in to slide the plug out. Once you do that there are screws behind those plugs. You'll need a phillips head to take those out. Then just pull out gently at the bottom of the speaker grill and it should come toward you then just slide it down a little and it comes right off. Behind that is the particle board screwed on in the center with several screws. Take that off and you can't miss the adjustment blok.

Bad Picture


You need to replace the convergence output IC's. I believe they are STK392-110's and there are ususally resistors that are opened due to faulty IC's. The IC's are located on a board behind the large speaker grill on front. There are 6 screws to remove to access the IC's. 4 in the back and 2 small screws behind the litte door on the front.
