Hi, you have an Optical Engine fault. Complete assembly needs to be replaced. This page shows the most common Hitachi Optical Engine Faults. Hitachi LCD TV Light Engine Optical Block Info
I have the exact same problem. I had purchased a new lamp shortly after the warranty expired and never needed to use it. I decided to install it today to see if that helped with the red glow. No difference. Someone else posted that when the TV is moved (we just moved from Canada to the US) it can misalign or damage some component. Still trying to figure out what that is...probably cost more to fix that a new TV!!!
your tv needs to be degaused or demagnetised.it cant be a bad picture tube unless it was dropped.
you can call a local shop to degause it in your home.rather easy and inexpensive to fix.
TV shows large red spot in middle of tv when dark show are on, you can see it more. Now blue spots on upper right side too. Spend way to much on this tv to have these kinds of problems only after 3 yrs.
Hi--Bought my panasonic pt-52lcx65 on sale for $2200 in 8/05. Replaced the lamp for about $300 in 1/08, just prior to Superbowl. Admittedly, this was to be expected after family members watched lots of tv over 30 months. However, two months later the blue spot emerged in 3/08, and red spot emerged 5/08. Set looks decorated by a Andy Warhol or Van Gogh wannabe. I'm looking for a fix it solution. Dr. Bob Heiliger, Lebanon, OH.
Tiny particles of dust on the light engine lens can cause this (and was a service call for me about a month ago), or possibly the expensive light engine.
