Black square in the middle could be closed captioning. Light engine is approx. $700 to $1000 for the parts alone. Time consuming job to change - 2 hours - so expect a hefty labor charge as well.

Growing red color starting in middle of tv and geting worse.


Both the 50v500 and the 60v500 have this problem.

It is a bad optical light engine. At first when the sets were new and this happened the part cost 1100 and then when so many started having it they dropped it to 225 for a while.

Now the least expenisive one is about 600 wholesale--not usually worth fixing considering the replacement cost with a new set.

Also: there are several class action lawsuits pending regarding both models for this problem.

The lamp used for a light source shines into the engine through a series of lens and baffles--heat from the lamp damages the engine inside--the new replacement ones are not supposed to have this problem. The engine has a lens on top that puts the picture into the mirror which puts it on the screen.

I am sorry to give you this news but if you have a fairly large oval "reddish or pink" area it is the engine.

If you do not have the set under extended warranty I would suggest you try to get involved in the class action lawsuits. Google the full number with lawsuit or light engine after it and you should be able to find this information.

Hitachi model 60v500a.the middle of the screen is a little yello


If you Google "60v500a light engine" you will learn a few things about this set which was first sold in 2003.

There are some class action lawsuits out there for several Hitachi models made at about the same time.

Most of the time these sets develop a discolored area fairly large in the middle of the screen---a lot of them had a large red or pink oval area but other colors are possible.

This set uses a LAMP for the light source and it directs the light into the optical light engine--at the top of the engine is a 3 inch lens that the picture comes out of and is directed into the mirror which puts it on the screen.

Lots of these sets develop a "burn" inside the engine from the heat--there are a series of lens and baffles inside---even slight separation inside will change the color in some area of the picture.

I am sorry to give you bad news but I have replaced a lot of these engines under extended and when they were new mfg. warranty.

The part is no longer available from Hitachi new--the only way to get one is to remove the one in the set and have it sent out for "rebuild" and the last time I saw one the engine was over 600 dollars at the wholesale level not counting the fact that it is major labor to replace.

Find someone in your area familiar with Hitachi and this model and you will see what I am talking about.

Even though this is not good news, I think it is what your problem is.

Round black spot in middle of the picture/screen


Hi :-)

The round blotch your seeing on the screen is the melting of an acrylic lens inside the light engine. Its a design flaw which unfortunately Infocus will not stand behind. To fix this problem requires opening the light engine and putting an equivalent lens in place. This task is very involved, but this problem is repairable and you need a glass smith to cut the right size lens from the original.

HAVE 56 INCH PANASONIC REAR PROJECTION--LARGE BLACK SQUARE RIGHT IN THE MIDDLE OF THE SCREEN


Hello MCNJC,
Get your remote and go to the close caption in the menu or the CC button on the remote. Set the close caption to off, or set it to CC1 to see close caption. NEVER set it to TEXT 1 or any TEXT at all.

Best regards

Color wheel replacement


With the back off of the unit, you are looking at a silver can on the light engine. The is the board where the DLP IC is located. There is a large heat sink right in the middle. Near that heat sink you will find a small square cut out where two pins protrude from the inner bd. There is a small black piece across those two pins, that is the jumper. With a needle nose slide that black jumper off of the two pins. Normally if the color wheel is changed and the jumper not remove the picture is very poor with ugly green and purple negative look.
