Moving from 60Hz to 50Hz
 

I'm moving from a 120V/60Hz area to a 230V/50Hz area and would hate to
leave my 61" Samsung HLP6163WX/XAA DLP behind. The instruction manual
dictates 120V/60Hz. A transformer easily takes care of the voltage, but
not the frequency.

Questions:

* Is the power frequency likely to matter?

* Will European HD picture be displayable?

* If I get a European (PAL) settop box that outputs up-converted HDMI,
will the American TV set be able to display the picture?

* Does the UL mark mean the TV set is likely to comply with EU RF
requirements as well?

My experience is that most electronics do not care about the power
frequency; the first thing that it does is transform the AC into DC. The
exception may be the clock; however, Japan has both 60Hz (west) and 50Hz
(east) so most modern Japanese electronics keep time internally rather
than rely upon the power line frequency.

It may even be that your Samsung doesn't care about the voltage either,
although I wouldn't risk it without a careful consultation with the
service manual. Most modern portable electronics have promiscuous
transformers, but a 61" unit may be a different matter.

* Will European HD picture be displayable?

I don't know.

I assume that any European HD tuner that outputs HDMI or component should
work.

After all, a modern DVD player can play DVDs from anywhere equally well;
the NTSC/PAL setting only affects composite/S-video output, not component.

* If I get a European (PAL) settop box that outputs up-converted HDMI,

Same answer as above. AFAIK, HDMI is HDMI.

* Does the UL mark mean the TV set is likely to comply with EU RF
requirements as well?

Probably not. The UL mark is a safety certification, and is independent
of what the EU bureaucracy comes up with. FCC certification is what
dictates RF compliance in the USA.

However, I doubt that you would have any problem with RF interference, and
I suggest that you follow the "keep mouth closed" strategy on this point.

I'd guess though that whilst HDMI is HDMI etc, the potential issue might be
if the US TV will be happy to accept a 50Hz HD signal on that HDMI or
component input (i.e. 720p/50 or 1080i/25) as well as 576i for that matter,
which is what a European HD STB will typically output.

Have you considered whether it may be too fragile to make the trip?
Usually 120/60Hz and 230/50Hz areas are separated by oceans. (Yes, I
know about Japan, but that's 110/60 and 110/50.)

True. However, it was shown in the 1980s that conventional analog NTSC
TVs could display PAL pictures with an analog conversion of PAL. I think
that one of the things that was done was to boost the vertical interval
level to help the TV lock on it. Older TVs would work too if you adjusted
the vertical roll.

576i may be a problem simply because that is not an expected resolution.
However, I was assuming that the STB would be set to output 720p or 1080i.
Given a digital signal, I suspect that it is more difficult to care about
the frame rate than not to care, especially with a slower frame rate.

But I guess that the only thing to do is to try.

Is Europe really going to use 720p/50 and 1080i/25 for its HD? That would
be a mistake.

I would bet that it had to make a trip across an ocean to get here in
the first place (unless all DLPs are assembled in Mexico).

That would be in its original packing designed for the trip, packed by
people who know how to pack it securely.

Most modern electronics are built with universal power supplies.
No transformer. They use switching power supplies and convert whatever
u plug it in to.

That being said, you need to research this to verify it for your unit.
It should be clearly marked on the unit, not necessarily in the
manual.
It may have a 110/220 switch. If it does it is probably not frequency
sensitive either.

In general, UL requirements are different and sometimes inferior to
the foreign counterpart. If the unit has the above capabilities, it is
probably a good bet that it was certified by a Euro agency.
HOWEVER, those certifications are not required for you to take a unit
from here to there and use it. It is a mfg to public sale requirement.
HOWEVER #2, if it produced RF interference to the point of complaints,
it is your responsibility to stop the interference as it is under any
voltage/freq.
