So my philips 32 inch tv went bad just before black Friday. Even though I grabbed a new Samsung to replace it on black Friday. I kinda want to see if I can repair it. When Its plugged in it makes a really whinny hi pitch sound coming from the inverter. The front panel acts as if there is no power at all. When I unplug it after its been plugged in for a while it makes a loud zzzzippp sound. I assume this is power discharging from the primary capacitor. When i disconnect the IO board it also stops making the whining noise. I assume it is a Io board from this behavior. My logic is that the IO board is the bottle neck and once its disconnected a fail safe in the inverter sends the power back into the circuit.
I can try to resize some pictures if some one wants me to but i cant see any bad caps. However I will be the first person to tell you i am not a electrical engineer so maybe some one here will know better. So what do you guys think?
