Mitsubishi DLP problem

What your experiencing is most likely a ground loop. If your tv has a 3 pronged outlet plug, try using whats called a cheater plug, which converts a 3 prong to 2. The lines will probably go away. There are other fixes as well. Do a search for ground loops and see if anything comes up.

Sorry to hear that... Well then it's obvious the issue is in the analog section somewhere... how about the antenna input?

I'm gonna take a stab at the vertical hold being the culprit. Older sets had an adjustment at the rear of the unit usually set into a spot off to itself. Slight turning of it either with a plastic screwdriver or fingers, if exposed, will usually remedy the issue.... that's what the 6SN7 TUBES USED TO HANDLE... VERTICAL HOLD. i THINK THEY'VE GONE ALL TO CHIPS NOW, BUT STILL SOME ADJUSTMENT SCREWS CAN BE PRESENT. SOMETIMES.

It also might not be sticking out of the back of the box either, so you have to look closely for it.... Call Mit and ask them about your model.

how about trying a different cable from the source to the tv. or how about trying a different input on the tv. couldn't tell if you tried this yet r not.

thanks for the thoughts.

I have tried different inputs. different cables. Same problem unless I use HDMI then it is OK. There is no ground loop. TV plug is 2 prong. I have tried it direct or into Shunyata Hydra 4 with same results.

I ordered a tech to come over. It was worth to have that extended warranty I never buy but in this case I felt I may need it. Still have little over a year left on it. This was a good timing for this thing to crap out.

I just reaplized that my friend had the same problem whith a 73" Mitsubishi DLP and they ended up giving him a new TV. This was a while ago.
Funny thing is, they don't make the 52" DLP anymore, which is what I have. So if they can't repair this one, I wonder what they will offer.

Ask the Tech what the prob was ... now I'm curious too.

Good luck.
