Re: 3 flashing lights, bad power board?

I want to clarify that the tv will stay on if no video signal is being sent to it.

The HDMI cable can stay in, but the instant I turn on the device feeding the video signal the tv shuts off.



Could a defective digital board cause an issue where the lamp won't light?

Re: 3 flashing lights, bad power board?

Hi Chubs, I have determined the sound is the lamp arcing but not lighting. I watched the lamp with the cover off, and the instant the lamp lights the buzzing stops. I can also see the lamp arcing coinciding with The noise. So the lamp won't stay lit even though it's a new lamp, and I bought 2 of the...

Re: 3 flashing lights, bad power board?

Well, I've been looking for the power supply but it seems no one carries it anymore. If I cant find it then my only option left would be to try to test/replace comonents on the board. I don't see any bubbled capacitors on the board. I noticed there was a scorched area around a group or resistors, bu...

Re: 3 flashing lights, bad power board?

So I connected a multimeter to the pins on the power board and it is maintaining 308-309 volts while on. When it shuts itself off and the lamp starts arcing and buzzing it will rise to 315 - 320 and then drop to around 10 after the tv shuts down.



This seems like normal operation to me.



Any ideas?

Re: 3 flashing lights, bad power board?

I pulled the resistors off the board and I guess they are 68k Ohm, not 6.8. They tested all within spec, between 68.2-68.5k ohms. I desoldered/resoldered them onto the board, and carefully inspected the rest of the board. No swollen caps or any other sign of damage. Re-installed the board and the is...

Re: 3 flashing lights, bad power board?

So I think it's the power supply at this point. I pulled the power board out and immediately noticed there is a scorched area around a group of 3 resistors, and the general condition around the area underneath the board is poor at best. I also have a new symptom, where before the unit shuts down, se...
