We have been using HDMI input on our LG 50 inch HDTV for over a year
now. Yet recently the picture turned "Pink" (black hues shown as pink)
with HDMI but not component input. I was interested in your response
to a similar problem - where you said that every time this has been a failed pwb. What is the fomal part name for "pwb", and is this board an easy thing to replace for the common electronics DIY person - and where would you recommend getting this part? Thanks for any help -Mark

Faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent.
That issue is with one or more of the board that drive the plasma screen. If you have a warranty, you will want to call LG for a free repair.
Sorry, but to trouble shoot that issue would require some TV tools and knowledge of electronics. There are several boards involved with processing the picture image to the plasma screen. I hope this information has helped you. Good Luck.
1.This issue sounds as though the TV connection circuit has an issue. 2. You have changed the DVR and the HDMI cables and you still have an issue with the video (pink screen) indicates a video circuit issue ( improper voltage or current) at the video section of the circuit. 3. This will require some troubleshooting by a qualified tech. 4. To make sure, try connecting another properly working LCD TV to the cable box or DVR an check.If you get a picture and sound properly it is the TV. 5. Usually a cable box is QA'd (quality assured) by the company and will not be sent unless tested 1st
I work as a contract technician for Vizio, and I can tell you from experience that replacing motherboard is one of the only solutions to this problem. The other solution if under warranty is to replace it. If you experience red, blue, or green pixels where dark shades (like nose, eyes, clothes, etc), call Vizio and accept nothing less than a full replacement! I have had situations where I replaced motherboard and within 2-3 hours the pixels return. Hope this helps.
I have seen several LG plasma that have a pink picture and everytime it has been a failed control pwb. This bd is located under the assembly that houses the main digital bd. The main dig. bd is the one with all of the inputs.
