SOURCE: black lines and menu problem
Check for bad caps in vertical circuit. Solder any/all bad connects. REPLACE vertical o/p IC w/OEM or better quality. I usually use Tosh,Hit,or Pana. 2)Check/replace tactil switch (menu)on front panel.

That is a convergence problem, as posted, it is called horizontal failure, to fix it it is necessary check soldering at the yokes, test horizontal convergence IC, test a couple of capacitors and resistors on convergence circuit, and sometimes the technician may have to replace a pcb inside.
The wole job starts from $80 and usually costs over $200.
To get service you can call the number listed on the owner manual, or look for support on website.
Let me know your location, and the current state of your guaranty if you wnat more information.
