Also could a diode be my problem

It's 6632L-0283A i did have backlight up until i changed that 2.2ul 450v cap i put the original back in but it still doesn't work

If that is the case, then I would recheck the works real well.
Can you show me where that cap is?

These are the two inverters in your TV, right?

OK, I need the DC Voltage readings on the MASTER Inverter board connector when TV is turned on.
Pin 1 VIN = ???? VDC
PIN 11 ADIM = ??? VDC
PIN 12 ON/OFF = ??? VDC
PIN 13 EXDIM = ???? VDC

I just had another thought. If the original 2.2uF capacitor was 45v, but you used a 450v part, I wonder if the ESR is too high?

And if the original one was faulty, that might be why it doesn't work when you put it back.

Pin 1 Vin 24v
Pin 11 ADIM .883
Pin 12 ON/OFF .883
Pin 13 EXDIM .883v when board flashes 1.3v

I know you didn't say to check it but I did
slave board pin 1 24.0 constant

Tom66 would you mind taking a look at this and let know what you think?

The Backlights (ON/OFF) is kind of low, I expect it to be more than 1V (you are getting 0.883V). Most panel uses around 2.5V minimum for BL_ON.
So what you can do is to remove the ON/OFF PIN from the inverter board, then use two 1.5V batteries connected in series to give 3V output, connect the negative to the chassis, the positive is connected to one end of resistor 330~1K Ohms resistor, another end will be connected to the ON/OFF pin of the inverter board AFTER the TV is switched on, the backlights should come on.

will try it tomorrow

Re: Philips/Magnavox lc370wx1 (sl) (04)

couldn't find a resistor anywheres never one when you need it

i removed pin 12 put 3.5 v with 3~1k resistor on pin 12 after board got power inverter would not flash blue again, until i removed the voltage then it flashed. the green light on the on/off switch was still green.
