Vizio vo47L 47" LCD. No


0ne of 3 has failed:
(in order of probability):

1. Backlight inverter
2. Power Supply
3. Backlight

More specifically on #1 and #2 - capacitors either bulging, leaking, or exploded.

Please seek the expertise of an experienced TV repair technician - as they contain potentially lethal voltages that must be properly discharged before work can begin.

Thanks!@#$

No, if the picture of your tv screen is clear when when you watching. the troble of your tv is looseboard, and you replace your CRT socket too.

Audio but no video


If the screen is not illuminated this can be from the screen power supply, the main screen driver board, or the screen itself has failed. The service rep will change boards to service this, and adjust as necessary.

The set will require factory level service.
