| JVC | AV-14FMG3B | JVC Tv,Model AV-14FMG3B. Power is ok & the power led is light normal. but there is no any picture and sound. it is stuck in standby. the power led is light normal (red ), but the ontimer led (orange) is blinking up to the TV is off. | Resold the vertical I/C. You have dry joints on that part.

| JVC | AV-14FMG3B | Jvc Tv,Model AV-14FMG3B. Power is ok & the power led is light normal. but there is no any picture and sound. it is stuck in standby. the power led is light normal (red ), but the ontimer led (orange) is blinking up to the TV is off. what can be the fault. | Could you check if there is any voltage e.g. on the collector of the high voltage transistor?
A blinking power-led, is usualy indicating a problem on the secundairy side of the power supply!
So try to obtain a diagram and meassure these voltages.
