As far as i know the tweeter is angled in the mount it does not look like the speaker can be angled as it appears to be fairly standard ceiling unit.

but the cover looks like a push on so maybe very careful levering might work.

Can't get face plate off of MTX 610CM ceiling speakers


Its a pain, espicially if the grills were painted before installation.

In the industry we use a "grill puller" which is nothing more then a wire hook with a loop for your finger.

If the holes are big enough bend a paperclip into a hook, grab it with needle nose pliars and pull the grill through the hole near the edge.

If it doesn't fit then use a small pointed knife or awl, stick the point in a grill hole around the egde and pull it down a bit, work your way around until you can grab the grill with your fingers.

Let me know if you need anymore guidance......be careful I've replaced alot of destroyed speakers!

Cheers,

Kevin

My color is off on my whole tv i have a 52''projection toshiba cinema series the old big style and was wondering how to adjust the colors so they match up


Sounds like what was wrong with mine! Take the remote and hit menu, then scroll to the Video Adjust button, then adjust the "convergence" or the color tone, brightness, contrast etc. My repair man did this and it helped get the picture much more life-like. He said over time they get out of line and just need a few adjustments. He just charged the $50 house call. Good luck, hope you can fix it.

I have a philips HD rear projection TV 60 in. inside there are six adjustment knobs. Three are color the other three are for brightness contrast and hue. Which is which Left to right


If yours is a rear projection TV the adjustment knobs on the focus block inside are screen (red, green, blue) and focus (red, green, blue). The ones you are referring to as color are the screen controls and they adjust the intensity of the color from each tube. The other set adjust the focus of each color. They are also not intended to be adjusted by the user. Unless major components have been changed these controls should not need adjustment. That is why they are inside the TV.

Csi sp-6c removal


Your speaker cover should either twist and gently pull off or may just need gentle prying with a small screwdriver. Before attempting is your speaker grill foam or metal. Some like my pioneers, you must gently remove the actual grill and not the entire facia itself to access the speaker removal. If you need to remove the grill, i recommend using a tiny screwdriver and gently work around the edges evenly. Steve

Green lines appear on the screen when dark picture is shown. Others have the same problem but can not figure out how to remove the front cover. Please help us


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
