Re: Sanyo DP42848 No Sound/Picture not the inverters
For a bit more clarification, the wiring diagram shows 5 points on the K8L where the BL_ON is located, but the K8L on my mainboard has a plug with 5 holes, but only 2 of which actually has a wire coming out of it. I've checked all the versions of the service manual listed above and its the same in each.

Re: Sanyo DP42848 No Sound/Picture not the inverters
I found a BL_ON that runs to the Main Inverter board, but it comes from the Main Board, and not the Power Board. I'm guessing it's the right one, as the only other things that come close are a BL_SW and a BL_ADJ which are all connected at the same place on the wiring diagram.
What should it test as if it's working?Leave a comment:

Re: Sanyo DP42848 No Sound/Picture not the inverters
Okay, i replaced the slave board and still the same problem.
No picture but sound. What should I try next?Leave a comment:

Slave, it was the VIT71043.51Leave a comment:

Re: Sanyo DP42848 No Sound/Picture not the inverters
oh, well the one on the other inverter board registered as open, so I'm guessing that is bad?Leave a comment:

Re: Sanyo DP42848 No Sound/Picture not the inverters
Ok, i tested the connectors to the inverter and they registered at 24v (23.87ish)
Checking the white fuse, the multimeter said it was short so I'm guessing that's the culprit?
would it be better to just replace both the inverter boards that trying to swap out this fuse?Leave a comment:

There's a picture of the inverter.
I had searched the forums before, that's how i knew what voltage to look for. Reading again now it says 24v, so I'm assuming that what It checked as before, but like I said, I'm going to re-check tomorrow.Re: Sanyo DP42848 No Sound/Picture n...re, that's howLeave a comment:

Okay, so using a flashlight I was able to read instructions to do an input search so I did that and got it to recognize my snes, and thus had sound. I'll edit my post with an image of the inverter board, and check the voltage again with the multi-meter.Leave a comment:

johnboy1313: I tried that with my phones flashlight, but to be honest it's not very good. I'll get a brighter one and try it with the menu button like you suggested tonight.
"Do you own a digital meter? " You mean a digital multimeter? Yeah, i have a Radioshack brand 29-range Multimeter.
budm: It's possible I'm mistaken, as i tested it a few weeks ago, but as i recall they tested to the correct number that i had read online, whether it was 12v or 24 i can't be 100%. I'll do it again and...Leave a comment:

Sanyo DP42848 No Sound/Picture not the inverters
Hi ALL!
I was given this TV by my father, it stopped working at his place of employment and since I've fixed some tvs/monitors in the past he said i could have it and maybe save it from a landfill or what not.
He told me the video went out, put the sound still worked. However, I plugged it into both my cable and PS3 and was not able to get any sound. I'm not sure how it was hooked up when it was working, and without the picture i can't be sure what input, etc. it's set on, but even cycling through the inputs didn't produce any sound.
I've tested the... -
