sounds like the Backlight has failed, if you look closely at the screen you should be able to see the image changing, but as there is no back light there is no luminescense so it will appear black or grey, It is probably the backlight inverter or element that has failed, if this is within warrany organise with them to fix it for free,

I had the same problem with my 42FD5994. It was working fine, then one day I turned the TV on and the front light turned green for about 5 - 10 seconds and then the TV switched to protection mode (front green light is now red and flashing constantly). I did some research and found out the the power board is faulty. I ordered a DIY fix it kit on Ebay for around $55 (includes shipping). The kit contains 5 high temp capacitors and a new IC chip. It also comes with a good detailed photo of the circuit board the components that needed replacing.
I also spent $70 at Radio Shack for some soldering gear and went to work. It took me 3 hours to replace the 6 components. The IC chip was a pain to remove, but one that was out the rest went pretty smooth. I had to remove two extra blue capacitors in front of the IC chip to desolder some of the leads.
After I cleaned the board with Isopropal alcohol (99% pure) to remove the excess flux, I inspected the solder joints to make sure I didn't solder some runs together. All looked good.
Next I put the TV back together and hooked everything back up. I powered on the TV and the same problem as before. The TV went into protection mode. But this time I heard the speakers pop and the screen buzzed. So I pushed in the power button to reset the TV. Next, I turned the TV back on, but this time when the light was green, I quickly pushed the power button again to power off the TV. I tried the TV one last time. I powered the TV back on, and with the remote I turned the TV on. Viola! It worked. The TV powers on great, and works like a champ. I am guessing that the first time I tried to turn the TV on, the new components needed a minute to energize. I also started the TV cold, I should have plugged it in for a few minutes before I tried turning it on.
So, I was successful fixing my 42FD5594 with the DIY kit on Ebay. I ordered it from California. The company was great, and Everything arrived well protected. I figured if this didn't work, it was time to get a new TV anyway. I can save the $2000 for another day.

If there is a failure in any of the scan circuits, the set will go in to protect mode. This is most probably what is happening.
Before starting to work on a TV set is is best to have the full shop service manual with the schamatics, with all the required service details about the set.
The fault can be any of the components in the associated cricuits. This can be a bad cap, open resistor, or a failed semiconductor.
In the case where a set is going in to the protect mode, it is difficult to take voltage readings, because the power supply is being partialy shut down. The parts of the supply that runs the high voltage and scan circuits are shut down, and also the uPC makes sure that the CRT is biased off to protect it.
It is most common that capacitors go out of specs with age. To properly test the caps you would need a cap an ESR meter. The other way to test caps is to replace them until you have worked out all the defective ones. This is shotgunning for a bad cap. With this method, you an end up changing a lot of caps, and they were not the fault.
In the case of the other types of components a DVM can be used to check them. IC's must be changed to properly check them. It is impossible to properly check an IC just with a DVM.
This is an idea of what troubleshooting is.

6 slow and 1 fast blink error on this model is vertical sweep failure. vertical ic's are located on large signal board. to verify error is correct would recommend disconnecting 1516 6 pin connector on lsb to msb as sometimes that board causes shutdown issues and if no change reconnect and disconnect crt anode leads going into hv generator and if no change replace large signal board
