Invalid cable card message when none is installed. we have cable service through a company. worked fine for 10 years and then we turn on tv and this message is on and wont go off.
Two things to try here---first is unplug the set for a while and plug back to see if the microprocessor in the set will reboot.
Second look to see if slot for the card has anything at all in it or is dirty.
if dirty blow it clean and repeat unplug procedure Note: very few of these sets have a hard reset feature but if all else fails call Hitachi customer service with the model number---they have some very good people answering the phones and an extensive data base on sets/problems.

SOURCE: Rear projection HD Hitachi Ultravision always has greenish tint
This is what you're going to do, Turn on the Tv and go to the service manual, if the green tint is still there, you have a defective dmd board, but if it's no there, then you have an issue with your video board

I think it would likely work if you trimmed it evenly around the sides in order to maintain the central position. Focus may have to be adjusted but thats all.

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.
IF YOU HAVE ANY QUESTIONS OR NEED ADVICE LET ME KNOW--I am here to help people.
