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.

Logitech speakers static


If you have just purchased these speakers, it is likely a loose piece inside, or the plastic buttons on front vibrating loudly when sound is played.

Quick fix:
Place a piece of tape over the buttons on the front.

Longer fix:
1. Remove both phillips head screws from the back.
2. Remove speaker guard. It is held on with 3 pressure pins. With a small flat head screwdriver, You can get underneath the guard and apply force. The trick, is to focus your net force perpendicular to the face of the speaker. You don't have to be too gentle, but be wary of flexing the plastic guard too much or it may break.
3. Remove both phillips head screws from the front.
4. Open speaker unit and remove two small screws from circuit board.
5. Cut two pieces of soft tissue paper big enough to fill the button housing underneath the circuit board. (The thinking here, is that the tissue will dampen any rattling from the buttons. Don't worry! The buttons will still work).
6. Re-assemble the speaker, taking care to tighten all screws.

Faint red lines in a curved arch like pattern


For this problem, what you have to do is here I found this solution: Right below your speakers on the right and left side are tabs. Pull out the tabs and remove the screw on eachside. Once that is done remove the speaker cover and you will see a fiber board cover in the middle of the tv, there will most likley be twist ties holding some wires, to make it easier to work remove the ties. Now remove the screws on the fiber board and pull it off. You should see 3 adjustments on the top for focus, do not touch those. Below the focus adjustments on the bottom is the blue, red, and green adjustments (they should be labeled). All you have to do is turn adjustment screw slightly to the left(or counter clockwise) and it should clear right up. That should do the trick, Hope this is helpful. Please dont forget your rating.

You should be able to get a replacement screen from http://www.rmslogisticslp.com. If so and you want to replace it yourself, here are some steps. You will have to do some soldering. I found these instructions when looking for help on my pantech so I am just passing on this help. If you aren't comfortable doing the work yourself then RMS Logistics may be able to help. You can also check with your provider for a store near you that services phones for that provider.

*****************************************************
This not a job for just anyone it will require some soldering on the circuit board. If you don't know how then it would be best to ship it off.

The steps to take apart the phone.
1. take the battery and Sim card out.
2. remove the molding place that surrounds the camera lens. It just snaps in. At first it did not look like it come off but is does.
3. remove 6 (six) tiny screws from the back of the phone.
4. lift the circuit board and carefully unplug the board in the next section. place the circuit board to the side.
5. Remove 4 silver screws, hold this piece to one of the sliders. - set this piece to the side.
6. remove 4 screws for the corners of this piece. two of the screws have covers over them
7. Ok this was a pain both getting it out and back in. you should see a circuit board and mic. The Mic is solder to the board and stuck to the piece below with stick-em. Carefully left the mic off do not break the wires - you just want it loose. Now lift the circuit board and carefully unplug the next circuit board. Set the circuit board and mic to the side
7. Remove 4 black screws hold the next slider in place.
8. Ok, you're down to the LCD piece. Again remove 4 screws in the corners. 2 of them have 1 long cover piece covering them.
9. remove the LCD piece, unsolder the speaker.
10. Solder the speaker just removed to the new LCD piece. and reverse the steps the reassemble.

Hope this helps.

Open up the front of the set by removing the speaker screen and the black piece of particle board. on the bottom right you will see 4 knobs. Turn those knobs slowly till the arcs go away. The 3 knobs on the bottom are for color. the 3 on top are for the focus.

SONY KP-57WV600 - Small green lines across the screen


According to several sites, the problem is with the convergence via the voltage on the color ray gun tubes that get out of adjustment. They are also known as retrace lines

Sony wanted between $150-$300 to diagnose and fix -- instead I was able to complete this repair in less than 15 minutes!
Since I had been through the routine once more and I was sure others are running into this issue,
1. All you need to complete this guide is one flat-head screwdriver and one Phillips screwdriver as well as a delicate touch.
2. Front shot of the television. Their are two screw holes on the front of the unit near the edge of each side right next to the speaker grille.
2_sony_projection_tv_front_screw_locations.jpg

3. Close up shot of the screw hold. It is covered by a plastic cover that has two tabs holding it in. Carefully pry them out with your flat head screwdriver. Do not apply too much pressure or you can break the tabs off. Once the covers are removed, unscrew the two screws with a Philips screwdriver.
3_sony_projection_tv_repair_screws_1.jpg

4. To remove the cover, pull from the bottom of the front case and rotate towards you. Once you rotate it out, the top will disconnect and come loose. Do not pull it off, as there are cords attached. (see picture) Loosen the cables attached with the twist ties and set the front cover to the left side.
4_sony_projection_tv_cover_off.jpg

5. With the speaker grille and cover removed, you now need to remove the wood panel to expose the inner electronics on your Sony HD TV. To do this, remove the four Philips head screws from the panel. Then, pulling from the right, rotate the panel off and the electronics will be exposed.
5_projection_tv_cover_guns_tubes.jpg

6. This is a picture of the inner electronics of your Sony Rear-Projection High Definition television. The little black box towards the front of the unit is where we will concentrate our time as it is the control for the voltage & convergence adjustment.
6_voltage_projection_red_blue_green.jpg

7. When focused in on the controls, you want to concentrate on the bottom row for the voltage / ray gun projection adjustment. The colors are labeled below and from left to right are blue, green, and red. Choose the one that needs to be adjusted and turn ever so slightly with your Philips screwdriver to remove the lines. In my case, the red just needed to be turned 1/8 of a rotation to be back in adjustment. Do not turn to quickly or abruptly or you could possibly damage your TV by varying the voltage too quickly.

I had the same problem with my sony KP-57ws500 rear projection tv. To solve this problem all you need is a flat and phillips screwdriver. Right below your speakers on the right and left side are tabs. Pull out the tabs and remove the screw on eachside. Once that is done remove the speaker cover and you will see a fiber board cover in the middle of the tv, there will most likley be twist ties holding some wires, to make it easier to work remove the ties. Now remove the screws on the fiber board and pull it off. You should see 3 adjustments on the top for focus, do not touch those. Below the focus adjustments on the bottom is the blue, red, and green adjustments (they should be labled). All you have to do is turn adjustment screw slightly to the left(or counter clockwise) and it should clear right up. I'm not a technician but i read up on it in a repair manual and it worked perfectly and saved me a $100.00 for a service call. It took about 10 minutes to do. I also have a friend who expiernced the same problem with a different model sony projection tv and it worked for his also. Apparently this is a common adjustment that needs to be made espicially if the tv is moved.
