I've had my 50V500A for about 4 years, and now have pinkish blotches in the middle of the screen when powered on. Powered off, it goes to black. (with a light, white, stripe down the middle) I can still see picture when powered on, but the pink hughe is maddening.. TVtechmaniac mentioned something about reinitializing the memory, and having a PDF, but cant find where it's posted. Would this solve my problem, and if so, where do I get the magic PDF? (or do I need a new bulb since it's 4 years old)

Re: Pink splotches on Hitachi 50V500A
We had the same problem and just got our light engine replaced last week. Yes, Hitachi will ship the part and they will pay for the part but they will ask you to pay for the install (unless like Dev23 said, it's still under warranty). Hitachi shipped the part to the certified Hitachi dealer that they recommended. Cost to us was around $400. Worth it to us being that the TV cost $3600 when we bought it 3+ years ago and up until we had the light engine problem, the TV has been great. Since the light engine was replaced, TV looks brand new. You will read some post about this problem were people have had up to 3 light engines replaced. Back when Hitachi was made aware of this problem (about a year ago) they were sending out refurbished light engines and not new ones...obvious cost savings and cheap way out for Hitachi. The tech that came out and installed ours said that now Hitachi only sends out brand new light engines.
You should really only deal with Hitachis Customer Relations Department and not regular customer service. When you first call, they will act like they have no idea what you're talking about. After you have someone come out to look and tell you that YES, it's a light engine defect, they will ship the part to the dealer and then the tech will come out and rinstall it. The customer relations department # is 800-654-70103.
If you're willing to pay the install, they will cover the part. The part we were told cost $1500. Regardless of a warranty or not, this is a DEFECTIVE PART and I think Hitachi should pay for the entire tab none the less, we just wanted the TV fixed without a hassle! Good Luck:)

most likely you have a bad buffer, if the redish area runs left to right take a ruler or something and see if its the bottom side or the top and pull that board, when u have the back off it will be on the left side connected to the y-sus, go on ebay there is a few people who sell them

you have what sounds like a very simple fault .the positor has failed a cheap three leg device in the power supply .it keeps magnetic feilds from effecting the crt/screen unless your confident with a soldering iron i would get an engineer as it is a very inexpensive component...if you need any more help drop me a line farr64[colin]
You have a problem with the light engine. Hitachi has extended the warranty on some of these. This is a major expense with major labor charges. Better get in contact with a local Hitachi authorized repair facility.
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 andholdthe 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 andConfirm the picture remains in a good condition. BE SURE TO COPY DOWN DATA SETTINGS BEFORE INITIALIZING I2C SETTINGS
It is very common for this model from what you spoke. If you handy return to me, Big Irish, and I will continue to help you.
99.9 % of the time of what you stated it sounds like a shorted CRT, picture tube. I have seen hundreds.
First, call the manufacture and complain about your concern and ask them for a CONCESSION because your tube has gone out.
2.If that does not work ; call a factory authorized service dealer to confirm problem and get an estimate, then return ti #1.
Good Luck, Day, Big Irish. I hope I helped.
Only a few causes for this problem. "Splotches" are usually caused by dust in the light engine which can sometimes be blown out using compressed air. Pink picture is caused by either data or burnt lcd card. Procedure for data is: put tv to ch. 3 and turn power off. simultaneously press input and power on set for three seconds to access service menu. Be very careful not to change settings other than what needs changed. These adjustments are changed using directional arrows. Navigate to "memory init" then hold (r) arrow button for 5 seconds. You will know if it worked. Then exit and/or turn set off. Please let me know if this is successful as I have additional info you may need. Good luck, Russmann.
