Question about Projection Televisions
I want you to check the cable box if all the wires are attached properly because sometimes it causes disturbance and vertical lines occur.
Here are few troubleshooting steps you can try:
ONE: Disconnect the power cord for 4 hours. Then when you power it back up the internal soft codes will automatically reset to factory defaults.
TWO: The whacking test is to just bang or smack the set with your hand on the back, side, top, etc., to see if there are loose connections or cold solder joints inside that are acting up. If so, the banging should knock them back to normal and the set should restore. You might have to use some creative banging and some have had to put a book or magazine under one corner to torque the chassis enough to get it to work reliably.
If the problem still persists you have to get it repaired the repair can cost anything between $200-300.
