Re: Vizio P42HDTV10a power no screen
Can't figure out how to get the darn thing off without a desoldering gun lol. I can't find my copper mesh stuff that takes the solder off =( My heat gun gets the solder soft but i still cant seem to get the darn thing to move!Leave a comment:

Re: Vizio P42HDTV10a power no screen
Ok, I couldn't figure out how to take the heatsink off. Tomorrow I will desolder the whole IC and test that way but i tested it on the board from the backside and got the following results:
VS - GND is open
VS - SUS_OUT is open
VS - ER_UP_OUT and ER_DN_OUT are both open
GND - SUS_OUT is shorted
GND - ER_DN_OUT and ER_UP_OUT both shorted.
SUS_OUT - ER_DN_OUT and ER_UP_OUT are both shortedLeave a comment:

I'm told that's the Zsus but yes it turns on and stay on with the board disconnected. Reconnect the board and nothing, it tries to turn on then some sort of failsafe kicks in and nothing.Leave a comment:

All of the fuses are intact. I did continuity tests on all fuses.Leave a comment:

I got a picture without the right board plugged in, i believe it's the Z-sus board. Screen came on and said GNAL in the middle.Leave a comment:

Re: Vizio P42HDTV10a power no screen
I checked all the power outputs from the power board at 222mv with the TV powered and on. When i first plug in the TV and power it on, i get 20V on the VS but that's only for a moment. It will click then buzz a little then nothing. During the buzz i get the 20V, after that i get 222mv. This is with the connectors attached.Leave a comment:

Vizio P42HDTV10a power no screen
Hi, I'm new here! I've looked around but can't find my specific problem anywhere. It's possible I missed it so I'm sorry to make another thread but here it goes!
My Vizio 42in plasma gets power but no screen. When plugged in the amber standby light is on. When I press power the light turns green and I hear the sound of a TV turning on, there's a click and a slight buzz then nothing. The light remains green but there is no display or any indication of any power other than the green power light. I need help on where to go from here. -
