Hi Pascal,
Blank screen and you can not see even the on screen display ( osd ) means the back lights ( cfl or led ) are not working. Please consult someone qualified to handle your set.Unfortunately there is nothing you can do yourself. Good luck.

Tip

Diagnosing video problems on TVs and monitors


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.

Relay clicking (chatter) is a sign that the Capacitors on your PSB are failing.

50 " Phillips Plasma tv. Screen is black, blinking red light.


Sounds more like blown/exploding capacitors on the PSB-Power Supply board. No OSD-on screen display a blinking led or chatter/relay clikcing at startup is the tv going into fault protection and bypassing the startup pins. The YSUS-Main controls the pic which is attached to 2 buffer boards the YBU-upper YBL-Lower. They control the upper and lower portion of the OSD and the YSUS controls both of them. Since you're getting No OSD you need to check for blown caps on the PSB first. Unplugging the set resets the error again. So you start all over again.
