Question about Hitachi 50V500 50 in. HD-Ready LCD Television
The screen has a big yellow circle on it. It started out as a small yellow circle in the middle then spread out to the larger screen. Hitachi told me I need a new lamp but other people told me it's not the lamp, it's the light engine. Before I spend $ on a new lamp, has anyone had the same problem? thanks. firstname.lastname@example.org
Just try to reset HDTV. If available and accessible, try using the reset buttons before
using the steps below. Using the reset buttons can save time.
1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

Projection TV makers charge an arm and a leg for their replacement lamps. They make it easy to do but as a result the custom lamp assy is expensive. The trick is to just buy the bulb for your model TV from any number of us aftermarket sources at a fraction of the lamp price and install it in the old lamp yourself. really easy. Some models are real bulb hogs though. Look them up on the net (include the word complaint or repair) before you buy, or you might be sorry. Many class action lawsuits out there - even against some of the name brand makers.

I had whole redish/pinkish screen on my 50v500 starting a few days ago, then I read through each of the threads on this site for the samilar problems on my model. I found TVtechmaniac's solution (pasted below) solved my problem. Thank you TVtechmaniac!
Enter the I2C Service Menu, be sure the power is OFF.
1. On the front control panel, press and hold the INPUT button.
2. Then press the POWER button for two seconds.
3. You may keep the INPUT button depressed until you see the OSD with the Service Menu displayed.
4. If you don't see the service menu, please repeat Process making sure you wait until the Power blinking LED stops.
5. Execute the Memory Initialize operation after the adjustment values have been written on a sheet of paper. Highlight “MEMORY INTI”, arrow to the right and hold the button to the right (approx 5 sec.) until a check mark appears in the box. This activates the Memory Initialization.
6. After the Memory initialize operation has finished (10~15 sec, the channel will revert to CH 3.) the pink image symptom should be fixed.
7. Write back the adjustment values from your notes to their respective adjustment parameters in the adjustment mode. (In other words, set the Data Values back to the the Data values written down before the Memory Initialization procedure). NOTE: Make sure the SELECT Button is pressed on remote after every change to the values. Failure to do so will result in the data values not being changed.
8. Exit I2C menu. Press exit repeatedly until you go back to the normal picture.
9. Turn the set off-on and Confirm the picture remains in a good condition.
BE SURE TO COPY DOWN DATA SETTINGS BEFORE INITIALIZING I2C SETTINGS

I have a Hitachi 50V710 with a yellow-greenish spot in the center of the screen. It appeared there about a year ago. I have been putting off getting it repaired because money has been pretty tight. And they told me that my warranty has expired. They also said that it would cost over a thousand dollars to fix the problem. I purchased the 50" TV 09/09/04 for a total of $3336.88 what a rip-off. Now the whole screen has a green tint and the yellow-greenish circle in the center looks brighter. I wonder if it is even worth getting it fixed? What will go wrong with it next? Its a Lemon.
I really regret not buying the 52" sharp that was setting next the piece of **** that got suckered into buying. I know I learned one thing out of this,
" I WILL NEVER BUY HITACHI BRAND PRODUCTS AGAIN! "
