    When starting up the TV, there is a vertical white line on the right of the screen. Sometimes there is a horizontal white line on the top part of the middle of the screen. I am not able to pull up any menus when the TV is on.

This blue seemed to be a 3 flash first then 4 flashes repeated then I could hear it shutdown. I replaced the 2 main power caps, mine were slightly buldged. I could clearly see...

    Hello everyone, I hope this is the right place for a question like this. I am getting a horizontal white line flash across my screen every few seconds or so when I'm playing DVDs. I originally suspected it was a problem with my HDMI cable, but I have since noticed the problem does not exist...

    Hi. Can someone please confirm the orientation of the ECM 8k mic for use with REW? I've been told that it should be pointed vertically when measuring? Is this correct? I've been using it horizontally. Thanks, Bob

    I've been using two vertically arrayed centers, one above and one below my small (plasma) and large (projector) screens for some time now, after years of using a single standard horizontally arrayed monitor above or below. The voicing is dead center, and very clear and articulate. I notice that...

    Hi guys, hopefully someone will be able to respond with a little help here. My old SOny KP53HS10 was having problems - no picture, so I found about about how to adjust the tube brightness and focus (hope I did that right) and the picture came back. But now there are 1 to 4 horizontal lines...

    i have an hp lc3260n 32" LCD screen and upon powering up it shows black and white horizontal lines through the entire screen then fades to black after 5 seconds. It seems as though the power stays on, however no picture or on screen display. I have checked most connections and no visible damage...

    I am getting ready to start hanging drywall. The wall which I will be projecting my screen onto should I hang the drywall vertical or horizontal? I plan to do a black widow screen directly on the new drywall. I am using 4ft x 8ft drywall and I will have approximately a 100" screen. If I...

    Several months ago I successfully completed the convergence repair on my Hitachi 51F500A. I did the grid adjustments to correct the convergence to an acceptable level without using a template (by eye). One thing that has remained however is the picture is too wide and I don't know how to adjust...

    New guy here with a problem. I own a WD62525 that just started getting horizontal stripes in the picture after the set is on for a while. I had the local repair man check it out and he said that the Mitsu tech told him the boards are bad/going bad. They suggested sending them in for and...

    It's a bad video, but this is what it's doing. The guy I got it from had the local TV repair shop out to look at it. He reports as follows: "they said something about a capacitor, or something like that, and that it'd be $200 or so." So, that's great info. Might as well be blinker fluid or...

    Hello all, I'm just getting into this, and am trying to use CARA for some room analysis. I have horizontal 2" faux wood blinds over a triple wide window in my theater room, and am wondering what the absorption coefficient or other acoustic data is for that combination. If anyone know this...

    I managed to get the unit to power up after replacing the caps on the DM power board, but now the picture comes on for a few seconds and then powers off. The diagnostic code I got was 23 -- Loss of horizontal deflection. Any suggestions on what to do? Paul R

    What if any are the reasons for not placing speakers on there side ( horizontal vs vertical) Is there a audible difference? I placed my surrounds on there sides so I dont bang my head on them when walking by/under them as I am 6'4" tall.
