Hi

I have a one year old Prima flat screen. The colour of the picture is
now sort of blue and purple and the picture slides down to a blank
screen with verticle lines. This is the exact same problem with the
previous TV (Different Brand) that also lasted less than a year.

The same problem presents it it is hooked up to the cable only or the
DVD only. This house is only 3 years old and I am wondering if there
is an issue that is not related to the TV.

I called Cable and they assure me there is no signal amplifier hooked
up.

Is it possible there is an electrical issue?

'issue' -what's that? i think you mean 'problem' !

this is likely unrelated to your household voltage, as the fault is
too specific. normally things just die or explode if the volts are
off ;-) I assume you have a plasma or lcd Tv? if it is a CRT then it
needs degaussing in the first instance.check also the connecting leads
and try it in another room. we need to narrow down the possible causes
of this odd behaviour.....

Good suggestion.

I took it downstairs and not problem (not even an Issue!!!!). It can't
just be a cable issue though because when the cable was disconnected
and only the DVD player connected the picture was just as poor. Any
more thoughts?

It is possible that one of the AC phases coming into your house is not
correctly wired. There may be a poor ground/earth connection. Allowing
noise onto the power circuit. Moving from one part of the house to another
may have moved you to the other phase (in the us, 220 2 phase is brought
to the house and some outlets are fed from one phase, some from the other.

You may have a device that is putting a strong signal of some sort onto
the AC line, that signal feeding through the power supply circuits and
upsetting the vertical sync.

Balderdash. :)

The OP said this is a "flat screen" but is it a CRT set? Someone else
mentioned this, but no apparent answer. If it is a CRT, sounds like
a magnetic field issue. Did you just install a megawatt stereo near
the TV?
