Question about JVC AV-27230 27" TV
Has white horizonal lines at top about 2in when first turned on then goes away after about 2-3min and one white line stays about 2in from top
Your posted description is a known (common) problem for the JAV-27230 and should be easily repaired. The vertical capacitor (C424 - 100uf/35V) needs to be replaced. It is relatively cheap and can be bought from any electronics parts store.
in some instances, it could be the vertical IC starting to fail or even a simple case of cold solder.
As always, extreme care when repairing the insides of a TV unit since HV can still be present even when off and unplug. A little knowledge of electronic components and use of a soldering iron should do just fine. Should you not be comfortable doing a DIY, then perhaps you can ask the assistance of a buddy who has some soldering experience.
Hope this be of some help/idea. Pls post back how things turned up or should you need additional information.
good luck and kind regards.
