Sorry to be so far off topic, and I will not be doing it myself!! You guys
seem to have quite an extensive knowledge of most things. My TV (24" CRT
Hitachi) has tonight developed a Pink tinge all over the picture. NO amount
of resetting etc, restores it back. Is this economically repairable does
anybody know? If we are talking under £50 I will probably try to get it
repaired but if over then I will probably go for a new TV, 42" Plasma sounds
nice, but i have to convince SWMBO.
If it is just a tint rather than a complete absence of green then it can
usually be adjusted. A clue is if it still does a reasonable white and
that it's the dark tones which are bad. Or the other way around. On older
sets these adjustments were made by internal pots. Newer sets it's often
software. Do a Google to find how to get into the service or engineering
*If I throw a stick, will you leave?

You have a fault in the degaussing circuit.Its probably the Posistor and
should cost about 5UKP to source plus about xUKP for "the tv fixer" to do
it. Prolly about 50quid in total if fixed in house - for about half an hours

On second reading (it IS late - and I'm "tired") an all over "pink" tinge
suggests failure in the green circuit or the tv. this could be a simple
re-adjustment of the drive to the CRT to early failure of the tube itself,
which, again can be "compensated" for by re-adjustment, but will eventually
result in failure. It depends on how old your TV is.Over 10 years - it owes
you no money, bin it.
It is an all over pink tinge, how do I do this "re-adjustment" as I cannot
see anything in the User Menus?
TV is approx 8 years old so I aint bothered too much if I "cattle truck" it
trying to re-adjust, but if I can get another week or so out of it whilst I
try to convince SWMBO that we REALLY NEED a 42" plasma it may help!!
I don't think they are.
The backlights do use power but they are fairly efficient.
I did notice that LCDs are usually brighter than plasma, one of the reasons
they tend to have worse black levels.
I can reduce the brightness on mine in addition to the brightness control
for the picture.
...I did say I was surprised.
My quick Google initially hit a cnet article that said LCDs over 42" were as
power-hungry as plasmas. Always fancying a bit of triangulation on such
statements, I did a quick check and I looked up 42" plasmas and 42" LCDs.
As it happened, I hit LG TVs which it seems are pretty comparable plasma to
LCD. I guess that's a good ad for LG plasmas since they are unrepresentative
of the difference which certainly does exist.
Your comment made me check further and this looks fairly definitive:
You are quite right, Dennis - plasmas generally seem to be around 50% more
power-hungry than LCDs.
If you feel that any of the above is incorrect,
Our plasma has a very dark black. With the room in complete darkness
and a completely dark scene, you see absolutely no light at all. Under
the same conditions the light from our LCD screen is very obvious.
I notice no appreciable difference between the bright of the plasma and
the bright of our LCD.
Well you wouldn't it should be the same as powered off.
Yes, fortunately most people keep the lights on and then there is more
Just like in a cinema where light leaks through the film.
Are they on maximum?
Try viewing them in bright light and see which is best.
Basically, if you want to view in the dark get a crt or plasma, in room
light either, in brightness lcd from a brightness point of view.
Actual perceived quality is down to you.
Nothing more true than that last sentence. I've been in homes where the
owners of a brand new LCD tv are crowing about the picture quality and, IMO,
it's bloody awful - strange smoothly pink faces, no detail whatsoever in
black areas, etc. Although it has to be said that a lot is down to poor
setting up. Sky had a superb setting up feature that downloaded with 'Sky
Anytime' on HD - but there are such mini progs on many DVD's.
Everyone to their own - personally I prefer plasmas - and Panasonic plasmas
at that. Yes they are more power hungry - but the contrast levels are high,
there is bags of detail in dark areas, and the picture is simply more
'natural' than lcd's (IMO!!). The picture quality on my Pana 37" is
excellent on standard digital transmissions - and superb on HD. Panasonic
regularly feature as best buys in Home Cinema mags.
