Hi folks, I'm a novice at TV repair and I need help diagnosing this set.
When you turn the TV on, it's hit or miss whether the back light comes on or not. When the screen does turn on, you can bring up the menu (I don't have anything hooked to it to know if the sound works).
Voltages from the power supply board to main board appear to be normal. The 24 volt pin registers 24.3. DRV ON registers 3.2 and PDIM1 and 2 are both 1.1v.
On the connector to the LED strips I get (from left to right on the connector) 112v, 28v, 74v, and 19v if the back light turns on. If not I get 56v, 0.1v, 56v, 10v.
Once you've gotten the TV to turn on, it usually won't come on again without being unplugged first.
Is this bad LED strips or else what do I need to check next?
