Re: Vizio E480i-B2 Won't Turn On DPS-167DP IC901
What would be a good replacement for the r915 resistor?
The markings on the resistor are F1/2J 4.7OHMS FU412 and its made by futaba.
Will this work?

Re: pn50b450b1d clicking
I ordered a new power supply and the tv powered up but it has some horizontal black lines.
Is there a way that i can narrow it down to a bad panel or y sus or buffer problems?Leave a comment:

pn50b450b1d clicking
The tv clicks and sometimes makes the chime sound but will not power on the whole way.
Va and Vs don't have any voltage.
When i jumper the board i only get 168v on the main caps when powered on.
I get all of the correct voltages on the connector that goes to the main board.
The power supply is a bn44-00274a... -

Re: Polaroid TLA-04641C clicking relay
I replaced the startup caps and now it powers on. I will replace all of the caps.
I would like to thank everyone for their help....Last edited by pop70458; 09-30-2017, 04:32 PM.Leave a comment:

Re: Polaroid TLA-04641C clicking relay
I checked it with another meter it will go somewhere between 442v or 435v for less than a second and then the relay will click and the voltage starts to drop until a hard click. The cycle just keeps repeating itself. There is a 47uf 50v cap and a 10uf 50v cap under the heat sink you referred to earlier.Leave a comment:

Re: Polaroid TLA-04641C clicking relay
The relay near where the ac voltage comes in is constantly clicking.Leave a comment:

Re: Polaroid TLA-04641C clicking relay
The 5vsb is a steady 5.1v with the mainboard cable unhooked. The main cap is at 170.1v with the mainboard cable removed.
When i got the 462v I measured the main filter cap while the relay was clicking. It would go to 462v then start dropping and go back up when the relay would click. I used the legs of the main filter cap when i got the 462v reading....Last edited by pop70458; 09-29-2017, 02:00 PM.Leave a comment:

Polaroid TLA-04641C clicking relay
The Tv's relay keeps clicking and the voltages fluctuate. The clicking relay is at location RE1.
on/ off 0.8V--5.2v
+5VSB 0.8V--5.2V
12V 0.8V--12.2V
24SP 0.8V--25V
24V 0.8V--25V
Main filter cap goes to 462V and drops with relay clicks.
Thanks for the help.... -
