I have a Magnavox 47mf437b37 47" LCD TV. The sound began to squeal, then the picture flashed a few times and died. I installed a capacitor/diode kit from LCDalternatives.com, along with additional diodes/zeners they later provided. I now have no squeal and the picture now flashes on twice, then is blank for a second, then flashes the picture twice again. Wash/rinse/repeat. LCDalternatives suggested I contact you guys for help. HELP!!! I can handle the component swaps, I may be able to check voltages if I have specific instructions. I am almost ready to replace the entire PSU.
Thanks for your help,
NN
