Question about LG Televison & Video
It's a LG 55" LED TV, model # 55LV3700-UD. When you turn on the power, the power light comes on, but the screen stays blank. The backlight test indicates that there is no backlight. The flashlight test - all I see is a reflections of the flashlight. What to try next? Thanks,
If you can't see a faint picture with the flashlight then the T-con board is gone. If you can see a faint picture, then the led driver or ballasts for the back lights quit. You can get parts from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

SOURCE: LG TV NOT TURN ON
To let you know , there jave been may claims against this 42" model There were some models released that had faulty power boards and video controller boards. LG recalled many of these to have them replaced
No picture and sound is Y +Z Sustainer problem.However, normally they have to change both Y Sus and Z Sus boards atthe same time. If you lucky than it's just a fuse on the Y sustainerblown (the chance is very rare) otherwise the IPM (Intelligence PowerModule) on the Y/X sustainer board is short. This is a common problemand costly to repair.
Is it under warranty or Extended 5 year warranty? If so get it repaired now.
