If you have tried using different input devices, looked for loose contacts
in power outlet, RC Jack, cable and connectors, the TV might need service.

Have vertical cyan lines 1 inch wide on same side


Don't know about your "primed" toner, but go to Diagnostics and run the PQ test. See what that looks likes. Go to Disable Cartridge Check and swap the black and cyan toner. Run another PQ test. Are the lines still there and are they black or cyan? If they are cyan, the cartridge is bad. If they are black it's not the cartridge. It going to take a tech to look at it.

Samsung 50 in. HPS5033X/XAA colored lines running vertically and won't go away.


How wide are the lines. Do they change width? Where on the screen are they located?Connections on the c boards at the bottom to the panel flex cables or bad c board itself can cause 2 inch wide verticle bar. Before touching these connectors be sure power supply is disconnected from the 2 sustain boards on the sides. If you don't there will be an arc that will destroy the flex cable thus you will have to replace the panel. If C boards or connections don't fix it the replace the plasma panel. If the lines are thin lines then panel is likely bad. Contact Panasonic even if out of warr they may help.

Insignia ns32lcd no picture just lots of vertical colored lines


Usually this problem is caused by the connections for the LCD Controller(TCON). If you disconnect and re-connect the cable until it works correctly it will usually solve this problem.
