Rear Projection/Screen Burn

[Jon H.]

I have a Hitachi 51G500A which is 22 months old. It appears I have done
some screen damage by "overpausing" with my DVR. Is there anything that
can be done to refresh this screen (even with out of pocket costs) or is
it a "done" deal....Thanks in advance (Pls post & Email) Jon H.

Three picture tubes, approximately $300 each, plus the labor to install
them and realign everything up. Shouldn't cost more than say $1200
total to get rid of the phosphor burns.

Outside of replacing the CRTs, not much can be done.

You can try the following, which will work to one extent or another
as long as the negative/reversed image is _exactly_ inverse of the
burned-in image:

1. Record a still image of the DVR pause screen with a completely
black background.
2. Upload the image to a computer and create an exact negative
of it (e.g. using Irfanview, Photoshop etc).
3. Record the negative still image back to DVD or tape.
4. Display it on the TV continuously until the tube burns disappear.
It might take hours, days or even weeks depending on how burned
the tubes are, and the color/size of the image.

This is not reversible. You will have to have the tubes changed. This will
be too expensive in relation to the cost of a new set. I have seen this
before with video games used on TV sets, or when the users leave the PIP on
all the time. Projection sets are very prone to this type of problem.

My suggestion would be to invest in a good LCD screen. You can leave an
image on it for a very long time, it would be nearly impossible to burn in.

My preference is front view displays over the rear screen projection. The
difference you see is very great.

You can have all three CRTs replaced, that's the only way to correct
burn. Cost is about $300 each for rebuilt tubes, plus the installation
labor and a full alignment. Generally a set with screen burn is
considered totaled.

What you are saying, in theory sounds like it will work. But, in practice,
it will not, because it will be impossible to have the exact matched
positioning, and characteristics. There will always be signs of burns.

There are many professional facilities that would like to have the solution
to screen burn problems. They would have saved a lot of costs if it was
something that can be reliably reversed.

I have also see a number of Plasma sets that are burned in from computer
games and etc. When burned, the set is considered scrap, because the cost of
replacing the display can exceed the cost of a new set.

We have a nice Fujitsu at work with some burn on it, at least it's
fairly light. Plasma panels definitely are not repairable if they get
burn. A really high end rear projection set can be worth fixing so long
as it's value warrants the cost of new tubes, or you may get lucky and
find a set of good tubes from a lightning or flood damaged set.

CRT ones may well be. ;-)

I'm amazed at what people will pay for a badly burned plasma. I've
noticed several go for close to $1000 on ebay even though new low end
plasmas are less than twice the cost.

This will reduce the useful life of your CRT's even further.

While I wouldn't expect it to accomplish much, if the CRTs have serious
burn then their useful life is already over anyway.
