Tip & How-To about Televison & Video
The first thing to always check is the MENU (osd - on screen display)
Push menu or display on your tv or monitor
- if the menu is clear, the problem is in the early stages of video or outside your device (could be the source (dvd, cablebox) or input connections
- if the menu is distorted, the problem is definitely a malfunction with your device the osd is generated from (tv menu distorted = 100% tv is problem)
* you can also use other OSD signals to troubleshoot - if the volume bar or display info (input label, info bar) is clear, problems are earlier in the circuitry or outside the device. don't be fooled by translucent menus or cablebox menus.
** osd is inserted in the picture in the later stages of video processing. if your osd is distored, suspect the circuitry after the video switch. this could be a bad LVDS cable, TCON or Logic board, or even a bad lcd panel, plasma panel, crt.
