Question about Hitachi 51S500 51" Rear Projection HDTV-Ready Television
Do you have the tuner locked out for use of HDMI input only?
Most of the time when a selection is not able to be hi-lited it is
because a feature that is activated locks out other selections.
Hope this helps,

Hitachi TV also Model # 46UX7K, Serial # W1H002013. I was hoping I can get help with this one too. The picture is dark and has lost most of it's color. I don't know if the color is off because it is so dark. Is there parts that I can buy from you to fix this problem.

This model uses two convergence IC's----if 3 D one or both are bad.
Most of the time this set uses either two of the STK-392-110 OR THE STK-392-150 CHIPS.
Both chips and any bad protection resistors around them need to be replaced and the set adjusted.
If you are able to do the repair yourself total parts cost will be under 30 dollars.
Some history for you:
This set like all rear projection tube type sets uses two chips---the ones in your set are Black in color--about 2 1/2 inches wide X 1 1/2 inches tall and are on either one large or two smaller heat sinks with fins on them.
When the chips are installed a white grease called heat sink compound is applied to the metal back of each---the grease transfers heat from the chip quickly to the metal it is bolted to.
After some years the grease dries out from the heat and one of the chips goes instantly.
You can buy a pair of the chips for your set on Ebay for less than 15 dollars plus shipping--
If you cannot do the repair yourself--shop around your area---most shops charge 300-400 for this type of repair. Whoever you get to do it make sure BOTH chips are replaced or you will have the same problem in a few months.
If you open the set and locate the chips---they will have the full STK number printed on them in white letters----there are about 12 resistors around them that need to be looked at--if any are discolored they need to be replaced.
If a shop says it HAS TO GO TO THE SHOP keep looking as any good tech can do this repair right in your home in about 1 hour---I know as I have done hundreds of them.
IF you can solder and are handy I will give you general instructions on how to do the repair and what you need---some people I talk to can either do it or have a friend who can do it for them---let me know
I can tell you what you will need aside from the parts and how to proceed with the fix---
If all this helped rate this solution---I do this here for free.

See if on the back of the TV, and on the computer you have an external type VGA type connector. You then have to purchase a long VGA interface cable to go between the laptop and the TV set.
The TV must be compatible to receive the VGA and external audio from your computer, and the computer must be capable to drive external audio/video devices.
Another issue that must be worked out is both the TV and computer must have compatible screen resolution rates. You will have to get the information about the display card in the computer, and compare it to the specs of the TV set. If these do not match up in to proper range you will either have a very stretched or compressed picture, or you may not be able to have any results at all.
If the scan rates are too far out, it is possible to damage the TV set!
If everything is technically correct, you will also have to purchase compatible cables to go from the lap top external audio output to the correlated audio input connectors on the TV. This is an adapter type audio cable.
For these cables, you will have to determine the connector end types on each of the units, so that you can go to any audio/video supply store and properly pick them out.
There is a simpler solution, but it will not have good picture quality. You can buy a VGA to baseband video converter box (if these are still available). These are not cheap but they can work if set up properly and the scan rates can be matched. You attach the converter box to the external VGA port on the computer, and then use its output via the proper baseband video cables to drive the TV set. The scan rates will still have to match. The quality will be very poor.
