TV Repair Questions? Ask a TV Technician
No the red light is steady. The tv was manufactured in feb. 2011.
I looked at all caps and found none popped or bulged.
The clicking is coming from what looks a small relay on the power board.
There are three of them (2 white, 1 black) and the black one is the only one clicking.
What should i look for next?
how much should there be?
Ok, there are 2 pins labled VS and 1 VA and 2 ground.
is either ground ok? or do i just go to the vs and va pins?
VA went up over 200
VS 1 went up over 60
VS 2 went up over 60
But after being plugged in for less than a minut all 3 dropped to almost nothing.
they all came back down to zero
with cable connected i get about 6 volts on all 3, disconnected, the 2 VS both go to a little over 200 and the VA a little over 60, but then almost immediately, all 3 start dropping slowly to near zero
Sorry but I dont know wich is the y, not sure I even had the Z. The one I have been checking is on the top left of the power supply board.
no change in power readings with either Y or Z disconnected, but with either or both disconnected, the tv seems to power up fine with no picture. It even makes the welcome tones and the little green LED in back stays lit.
But plug them back in and nothing but clicking. Also with the cables disconnected, I can use power on/off button, but not with them connected.
Do you see all the square black chips on the extreme left side of the tv? If you look close at those chips, do you see any holes or burns in them?
They all look fine, no holes or burn marks.
I don't know what the policy is, but if I give you my phone number, would you be willing to walk me through trying to figure this out over the phone?
Ok, before I do that let me give you some more info.
While waiting for your last answer, I decided to try some more troubleshooting. In the pic i sent, the ribbon cable that crosses at the top of the tv, Y to Z? When I disconnect that from the board on the right (Z), then plug in the power cord, the tv powers up, makes the welcome tones, then the screen flashes some multi-colored diagonal lines for a second then goes black.. Also with that cable disconnected, I can turn the tv on and off with the button on the front whereas with it connected, I cannot.
With that cable connected there is no welcome tone or flash of color on the screen when i plug in the power.
Am I going backwards here?
Hey Tim, been real busy and have not had time to work on the tv, will be busy for awhile with hunting season. I will accept answer and pay for now but will be back another time to continue.
Thanks for the help so far, Mark
