I have an Hitachi 50v500 LCD 50" TV that blue streaking happening. I discribed it in a previos query as blue shadow but it is definately blue streaking mainly right in the middle of the TV. It's only 3 years old and I am just sick about it. Helppppp!
Solution:
- I am not expert but before you go to a lot of trouble, read all of the post on the infamous "red cloud", "red blob" and "blue streaking". In evey case, it appeared that the light engine was the problem. We just had our light engine replaced and the TV looks perfect. We dealt only with Hitachis Customer Relations Department 800-654-7013. You will have to have a certified tech come out and diagnos the problem. Hitachi will then call and verify, with the dealer, that the problem is a defective light engine and will send out a brand new one.
We were told the part cost around $1500 (Hitachi covers that) however, they will ask you to pay for the install. Our install cost $400. Worth is to us as we paid $3600 for this set 3+ years ago and we have loved this TV. When you first call Hitchi, they will act like they've never heard of this problem but they will give you names of certified techs in your area. Once the tech confirms that it's the light engine, Hitachi will own up to the problem and send out the part.
You really should only deal with Customer Relations ( I listed their 800 number above as you will be chasing your tail so to speak with their regular customer service department. Good Luck!
