okay i have a 42'' Vizio that i brought about 3years ago..it recently went out (no pop sound) just went black..the sound was still there but no picture at all..everything was functional..power on/off ,volume,changed the channel that also worked...just couldnt see anything...so after much research i decided it was a bad inverter board...i opened up my TV and notice 2 bad caps on the slave board..so i changed those out,thinking i was good...but STILL no picture..so i then checked to see if i had 24vdc goin to the master board and the slave board via the power board...which i did...so now im confused..its not the power board...the master board looks fine..the slave board got the bad caps replaced and still no picture...
now when i first took the back off the TV and plugged it in as soon as i turned on the power i saw a "blue spark" comin from the masterboard and that didnt look right...so im leaning towards replacing the masterboard or both boards all together...i called a repair shop and they said it would cost around 300-400 to fix it....FUCK THAT!!!!
any clue what it could be?
