Worth trying a t-con swap?
TV Model: Panasonic TH-50AS610Z
Serial: MG4660026
Type: 50" Full HD IPS LED LCD Smart TV (2014 model, NZ version)
The Issue: Multiple vertical lines running full height of screen. Mix of thin white/pink lines and a cluster of rainbow lines in the centre-left area.
What I've tried so far:
Full power cycle
Opened back panel and cleaned all ribbon cable connectors with IPA — found insect debris (chiton) in connectors and around the bottom of the TV
Reseated all ribbon cables including LVDS cable from main board to T-Con
Discovered loose LVDS cable which when reseated brought the picture back but lines remain
Lines appear on all inputs including the TV's own home screen menu so it's definitely internal
Current state: Lines still present but possibly slightly improved compared to when first purchased. Right side of screen appears clean with no lines.
