Re: Help identifing this part. Picture included.
The person I bought the main board from said he could not test it completely and guarantee it was 100% good so he refunded me my money. He also told me his technician said that 90% of these models tvs have problems with the daughter board, that most people replaced the main board to not fix the problem. So I ordered a daughter board from shopjimmy for a third of the price of a main board. For now I will patiently wait for it to arrive.

Re: Help identifing this part. Picture included.
I measured voltages coming into the main board (the board I ordered) I found no readings of lower than 3.3vs. When I put the new board in I will take some more readings and compare them with the old board and try to pinpoint the problem, then repair the old board.Leave a comment:

Got tired of messing with it. Went ahead and ordered a new main board. Should get it back Friday, will post results after I swap them out.Leave a comment:

Re: Help identifing this part. Picture included.
I suspected the regulator with the red star was at fault reading 0.00v on adjustment pin, 1.25v on the output pin and 2.06v on the input pin. I swapped a new one in and now getting a reading of 0.00v on adjustment pin, 1.25v on the output pin and 2.06v on the input pin. Anyone have any input on this?Leave a comment:

Thread can be closed. I found the faulty regulator and just paid for a replacement. Will post back the results after I slap it in.Leave a comment:

Re: Help identifing this part. Picture included.
When plugged in the Vizio power indicator is lighted orange, when powered the orange turns to white, the back light fires up. The screen lights up gray. I get no response from the power, volume, channel, etc buttons on the side once turned on. I would rather pay a few bucks to repair the board than dishing out $100 for a replacement board.Leave a comment:

Re: Help identifing this part. Picture included.
I have labeled the voltage readings for the regulators in the picture. I found another (smaller one) that has a 0.00v reading on the adjustment leg....Leave a comment:

Help identifing this part. Picture included.
I bought this non working Vizio tv, opened it up and found a bad voltage regulator (circled in the picture). I was getting a reading of .58v on the adjustment leg. I have searched the past 3 days on the internet for a replacement but have gotten nowhere.
IIC?
1084
0808BL
is printed on the top of it.
I would appreciate any help identifying a replacement for this. Thanks in advance....
