Vizio VO47L FHDTV10A Orange>White Logo, No pic
Hi. Complete rookie here.
Story goes, the picture on the VO47L dies and a puff of smoke appears. I opened it up and cap C241 on the power supply spewed acid all over the heat sink. So I think, "this is easy" and grab the correct cap, 105', 470uf35v and replace it, no problemo, working great!; except, 1/2 day later, the picture goes black again. Open it back up and the same cap is bulging.
Then I notice (yes I'm a noob) that the caps on the inverters (master/slave) are leaking. Yikes. So this time I order Panasonic caps for the inverters i.e. 680uf35v105' and a Nichicon 470uf35v105' for the PSU and solder them in. So, here we are today:
On power up, the tv clicks, orange Vizio logo turns white, the PSU connectors, CN2, CN3, CN4, CN5 have the correct voltages e.g. 24v, 12v, 5v, exactly as they are labeled on the board but NO PICTURE. :cry:
I checked my solder job on the inverters and it looks okay for a novice (my 1st time). Yes, polarity is correct.
Next step (if you think this is a good one) is to check the fuses on the inverters but embarrassingly, I don't know what they look like and double embarrassingly, I don't know the procedure for checking them (continuity test, right?)
Attaching pics now. As always, HELP!
p.s. TV will power up/down
