Question about Projection Televisions
Sounds like a classic convergence problem. most likely bad connections on the bottom of the stk's. If a repairman were to do this for you it would run $300-$500, if you were to do it yourself it would run less than $100. Bad connection on the vertical IC can cause something simular to this as well. If you need more help or would like to fix it on your own please let me know

Tips for a great answer:
This is an indication of out-of-regulation in the power supply section. This is
cause by leaky/dried
electrolytic capacitor in
that section. It will dropped the supply from normal voltage and
will disable the unit.It needs a little warm-up to make itself stable but the
symptom will get worst until the unit will not even power up. Sometimes it has
a bulged/dome at the top but not all, it is better
that you have acapacitor checker/tester to determine its condition. Your unit
will back to normal again if the leaky/dried capacitor is isolated. If you don't have a capacitor checker, replace all electrolytic capacitor in the power supply section, it will not cost you much because this is one of the cheapest part on that board. Watch this video for more info regarding electrolytic capacitor.
If you don't have necessary tools
and test instruments, and can't do the job yourself, I would advice you to
look for a professional to troubleshoot the problem. Don't
attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored
electricity enough to hurt you with a little mistake only.
Hope I helped you.
Have a nice day!
