Question about Hitachi Televison & Video
Start going to the video settings menu and do a reset check page 33 of user manual here .
If you are using the TV connected to a computer, see also PC mode control to set display width at page 62
Try doing the reset suggested above, see if they work, leave also the TV unplugged for few hours tonight.
Generally, if the bands appear only for some times , then image expands regularly it is a faulty IC or capacitor, that works fine only after it warms up.
I work on PC monitors etc.I have not serviced your model yet, and I don't have the service manual to follow the troubleshooting diagrams to locate faulty area on the board, test parts and find defective one.
If you want to DIY here is the service manual.
Here you get all parts for your TV.
If you want to call a technician there is a number listed at the end of the user manual.
If I find any free schematics I will post here.
