I just read your entry "... you have to take off the front speaker
cover and a small panel under it..." How do you remove the front speaker covers? I don't want to remove any more screws than necessary :) Thanks!

The lower front speaker grille will need to be removed first by removing the screws along the back edge of the rear cover as shown in the pic below. then just pop the lower speaker grille off then you will see the screws along the bottom edge of the front control panel and also on the rear edge again then that panel lifts off but you will need to reach behind as your removing it to unplug the wires that are hooked to both small circuit boards on that panel ( keyboard & aux input boards)
u need to adjust the focus screen , this is located right under the picture tube , u need to take the front speaker grill off , look close to the botton of this grill and u would see a small cover that is covering the screw , remove ths screw and pull hard
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
i see this alot of at the shop. i believe what you need to do is to remove the front panel with the buttons. to remove this remove the torx screws in the back of the front middle pannel.if you have a model with a soft speaker grill it jus pulls off the front. if there is a hard cover there is more torx screws on back of grill. then there is few torx20 scress under the front middle panel. then just remove the connector
HELLO Iit can be accessed thru the front of the set. you will have to remove the screws that hold the speaker panel on the front of your set. !!! after removing the speaker panel you will see a small square box with a handle with two screws holding it on, you will have to unscrew those and pull on the handle to remove. hope this helps. "GOOD LUCK"
Do not remove the rear panel with the power cord still plugged in on your model or you will instantly wipe out the digital circuits. Its a safety feature. remove the front speaker grille screws are on the side and inside the door under power button. Then after you remove the speaker grille remove the small access panel and you will see the convergence board on the right side thre are 3 wire plugs on the right side of the convergence board. Un plug thos 3 wire plugs and try to power up the set if it powers up the problem is convergence. If it doesnt its the deflection. If you need the deflection board go to the following link they have one. http://servicemanuals.vstore.ca/
do not remove the back panel to that model with the power cord still plugged in cause if you do the digital section of the TV will be completely wiped out. The convergence board is in the front behind the speaker grille and small access panel its the first board after the access panel its on the right side rectangle board. You can get a convergence board at the following link just leave an email with your model number and what your needing. I work there as a support tech and they just got those boards in yesterday and havent even listed them yet. Heres the link. http://servicemanuals.vstore.ca/
You have to remove the speaker cover under the screen and controls. It says Mitsubishi on it. The speaker cover pulls off. There are some screws under the control panel that have to be taken out. Then follow the 2 sets of wires from the control panel and unplug them. You can then lift the screen up and it should come off.
The front panel normally has some screws that need to be removed from the inside of the set. You need to remove the back cover first and you should see the screws. Then the panel pops off. Good Luck
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.
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.
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.
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
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.
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 hope this guide worked for you?
