Try hitting "TV/Video" on the remote control or on the TV. Someone may have accidentally hit this, so that the TV is trying to display a picture from your VCR, DVD player, etc, even when nothing is coming from those devices.

57wv600 blinks 7 times, no picture, or blue for few seconds


1. Remove the 5 screws from behind each speaker
2. Grasp bottom center of plastic panel and "pop" forward. Swing upward to remove.
3. Remove 4 screws from the wooden panel in center.
4. There is a "black box" in the very front of electronics. It will have torque paint on the 2 rows of 3 screws. top row is labeled "focus"
MY TV would go green before going black. Volume still worked.
5. I turned the center bottom screw (marked "green") appx. 1/8 to 1/4 turn COUNTER clockwise.
Plugged TV in and it works fine.

Our Hitachi tv turns on okay but the picture on comes in for 2-3 seconds and then the screen goes black. Last night the tv work just fine but this problem started today as I turned the tv on to watch...


I don't know what model you have,but... I have a 50v715 and it was doing the same thing and it turned out to be the lamp. So if you have not replaced the lamp in a while then it could just be it time. Hope this is helpful.

My screen turns green and then turns off


you need to adjust the screen voltage. behind the front grille and inside cover. a small black box 6 adjusters protruding from it. only adjust the the color counterclockwise that matches the problem in this case it's the green so look for the knob with "G" marked by it. there are 2 with "g" marked by them the row across the top of the box are for focus don't adjust. back the knob off untill the raster is blank with your input set to an inactive input, the picture should be blank and black.
when it is you have the adjuster close to where it should be, now change the input to an active signal and turn the color off so that you wil have black and white picture. adjust that knob untill you do have a truely black and white picture not too green or red or blue. go back to inactive video input and check that there are no lines of any color on the screen. repeat if needed. always adjust these knobs slowly the set will be watching you ! if your autofocus won't work now you have the adjustment set too low. check this function before putting back together again. these adjustments can be real touchy so be patient

Screen went black


Remove the front grey bottom panel of you TV (don't forget the 2 screws behind the front AV cover located just below the power button) then remove the panel behind the grey panel. You should see 2 heat sinks on the front right of your TV, place a fan near your TV and have it blowing on the heat sinks. Now turn on your TV and see if it stays on longer then it has been. If it does, your DC amps might be overheating. If they are, you might be able to fix your problem by adding in a little more heat sink compound between your DC amps and the heat sink itself. You can find the compound at Radio Shack for about $5. let me know if pointing a fan directly on the heat sinks helps.

Screen goes black after unit is turned on.


Contacted Mitsubishi directly and found out that QV9 on the remote control resets to factory defaults, clearing the Parental lock out someone had put in place. The TV is in a Retirement Home and some of the folks are sneaky about wanting to control the TV in their own fashion. We will be watching the remote a bit closer now!

Black box on screen


This happened to me and it turned out the closed captioning on my TV were activated somehow. I never even touch the controls on the TV but I had to manually check the settings on the TV and found that the captions were on.
