Hi i have this 60" vizio plasma 2007 model i checked all over and there is one thread about this tv with different symptom and its old thread anyways thanks to bad caps i have fixed alot of monitors and 2 plasma and 3 lcd tv's again thanks everyone but this one is a bit of a trick even with the service manual i found this thing has 4 power boards 1 for sound rest for system i might have overdid myself but i paid 100 dollars for it in its condition anyways here is the link to the manual
okay here goes i get power to the sound power supply and to the 1 of 3 power supplies and get 59 volts to the other supplies its supposed to be 65 and no standby voltage and no sings of power after that no va/vs/ nothing notta no power going to the mainboard none to y and x sustin's and nothing anywhere else DEAD!!!! no fans no clicks notta ziltch, exception of a speaker pop when you unplug it. and these supplies are expensive except the 1st one i found is around 60-100 but the big supplies are a tad high 150plus. it's safe to assume its the power supplies one of em or 2. The guy i got it from siad a vizio tech swapped the mainboard and same results, question i have is why did he think it was the mainboard?, when it does not get any kind of voltage to think? am i missing something here? and yes i checked all the main fuses all are good. Any idea's any lead would be greatly appreciated!!! here is few pics prolly not best of the power board 2 and 3 there huge and hard to get good pic's will add more if needed Thanks!!!!!
