Sometimes the picture rolls for 30 minutes to one hour and then the picture is perfect. A few times when we turn it on, the picture is okay and then after a few hours, the rolling picture starts. Where is...


The rolling is a bad filter capacitor on the signal board in the set---Any Mitsubishi dealer can look the model up and see known faults including this one---some of the sets when cold---vertical jitter in picture or just menu---If the menu is stable you have a tiny bad cap= weak caps when cold act up and when get hot regain capacitance and start to work.

Security light blinks when key is turned to on and will not start, also is the key supposed to be coded? 2003 saturn vue 2.2


Ok to learn the key you have to do what is call 10 minute learn , turn the key to start in attempt to start the car without turning the key off after you do this leave the key on for 10 minute until light goes out, After the security light goes out turn key off for a second or two and then try to start. If you have a new key you have to do a 30 minute learn you have to do the same thing as you did for the 10 minute learn but 3 time try and start without turning key off wait 10 minutes until security goes out then try and start again and leave key on, after you do this 3 time (30 minutes) the 3rd time is where you turn the key of for a second or two before starting.

Hello i have 2001 Mitsubishi montoero sport to day took the battery out and now when i try to start it, it runs for a second or two then goes off


disconnect the battery again, with it disconnected press hold the brake pedal for 30 seconds, leave the battery disconnected for 30 minutes. reconnect battery, turn key from off to on and wait 2 minutes, start the vehicle (don't touch the gas or brake for 5 minutes) this is what I did on my friends montero and it started right up and ran fine, only thing I could figure is that I caused the computer to reset and recalibrate itself, but i'm not real sure. worked for him maybe it will work for you... good luck

Motorola DCH3200 cable box: sound and sometimes video cutting out


Sounds like your SNR is getting too high and causing the signal to overload. A few things can cause this a bad splitter that causes the signal to bleed and introduces noise, or a more common issue is having a weak signal coming from the cable provider and once it goes through a splitter it causes the signal to become to weak to be stable.

Since it sounds like your cable has been working up until recently, you may have had a cable or splitter go bad.

Call comcast and have a technician come out and test the line.

2 new problems with my TV after my move


Well it may just be the signal in your area that isn't quite as good. That's just fact. Also, because the signal may be weaker, it may take longer for the TV to fine tune to get the best picture quality, which would explain the slight blurring after turning your TV on.

Bouncing Picture on WS48511 MITSUBISHI PROJECTION TV


I have seen this symptom a lot recently. There is a 9 volt regulator on the small signal board, and the output voltage on this IC has dropped down to about 8 volts, which causes that symptom. Replacing that regulator should cure your problem, and when I make a housecall for a set like that I charge $150, although I hear that the average service center charges a lot more than that. I also believe that it is never a good idea to leave a projection TV on all the time, so whoever told you that has no idea what they are talking about.
