    How do you reset to factory settings? Are we talking about all of the setting on the screen or the color settings?

    This TV zooms the picture when a bright scene is on the screen. When there's a picture that is dark, the reception is normal. When there is something bright on the screen, it's as though someone is pushing a zoom button & the picture expands sending the top & bottom portions off the screen.



    Sometimes when a mixed picture that is a little bright appears on the screen, then the TV just jumps as though the horizontal or vertical hold is faulty. This TV is about 15 years old. Do they still have horizontal & vertical holds for these TV's?

My mitsubishi projection tv comes on and works fine for a few minutes then lines like a verticle hold in different colors mostly green flicker up and down the screen like a verticle hold, I would like to...


Mine has the same problem. This kind of TV does not have a color wheel. I changed the 4 1000 uF caps on the DM board like advised here, but it did not fix the problem, but it did change it, so I suspect it's a similar problem somewhere on the signal or main board. The caps were getting ready to burst.

Picture up side down


change the verticle cables on the deflection coil on the tube.
note just the verticle cables ( verticle has only two cables)
what is happening is that current is reversed.

get it to some body a tech.

my tv gave me a similar problem.

Logik lt2974 small picture


the problem is in the verticle section, if you are a technician check a verticle IC and a capacitor of that stage. to allocate a verticle stage follow 4 cables coming down from deflection coils, two of these wires goes near transformer, this is horizotal and the other two goes near an IC this is verticle. positive idea.

The picture rolls vertically sometimes.


I would check the capacitors in the verticle deflection circuit. Also try resoldering the verticle output as well as the verticle yoke pins where they connect to the chassis. Mitsubishi has had some trouble with their capacitors, you may have one that is leaking. Let me know if I can help you further.

Trouble!!


Most of the time when theres no picture on a mitsubishi projection set, theres no verticle sweep. Most likly cause is the verticle output IC or the b+ feeding the IC or Both. This is not a consermer replaceable parts. It could also be the PIP module if the set has one . Remember these sets have alot of hi-voltage even when the sets unplugged. Good Luck
