Re: Sanyo DP58D33 sound but no picture
Here are what I think are the tabs on the side of the panel....

Well dang. Couldn’t be something simple could it...lol.
Possible to replace those smd’s? Worth messing with?Leave a comment:

Re: Sanyo DP58D33 sound but no picture
Sorry, I’ll try to clarify. I misread my probe to probe test. On the bad side, using the red and black probes I can test either side of the caps with them and get 10-11ohms. On the other side with the probes testing one way I’d get O.L or I guess infinite resistance and with the probes reversed they’d get either around 7 M ohms or ~100 M ohms.
I did the test without the T Con board connected and no power connected.
Could you explain what you meant by “the side” for pictures?Leave a comment:

Re: Sanyo DP58D33 sound but no picture
No obvious damage that I can see.
Resistance on the bad side shows 10 to 11ohms with either meter lead on either side of the sdm. And it's the same for every capacitor on that side.
On the good side the capacitors are lead dependent. One side showing no resistance and the other way shows readings in the milliohm range....Leave a comment:

Alrighty, I'll pull the bezel and have a closer look at that stuff as well as take some pictures.Leave a comment:

Re: Sanyo DP58D33 sound but no picture
I did more research into TAB failures and what they are. I'll look closely at the failed one that's attached to the panel, see if it's pulling loose or defective in some other obvious way.
Anyway to test it with a multi-meter? Or is it mainly visual/putting pressure on it with the screen on?Leave a comment:

Alrighty, I'll look into that tonight or Sunday night. Thanks!Leave a comment:

Re: Sanyo DP58D33 sound but no picture
Being a noob, I'm not sure about some of the things you mentioned here. Somewhere I can look to see where on the board you mean and how to test?...Leave a comment:

Re: Sanyo DP58D33 sound but no picture
I attempted the left ribbon connector first, the screen stayed black. When I removed the right one, that's when I got the split screen....Leave a comment:

Re: Sanyo DP58D33 sound but no picture
Would swapping to the original T Con board and checking for the split screen be beneficial?Leave a comment:

Looks like you were on to something, I'm not sure what it means though. Second picture shows which one was disconnected when I got the half screen....Leave a comment:

Those the ribbon connectors from the T Con board going down to the panel?Leave a comment:

Re: Sanyo DP58D33 sound but no picture
Anything else I can check out? LED's? Or is there a way to check the panel?Leave a comment:

Getting 12.23V on both sides of the fuse and the bottom solder point on the VIN12.
I bought the TV new. Worked fine for about 5 years until this issue. I swapped the T Con board but that’s the only work that’s been done on it.Leave a comment:

Picture 1: Overall
Picture 2: Powerboard
Picture 3: Mainboard
Picture 4: Subdigital board
Picture 5: T-Con board
I'll need help finding the fuse you're talking about. This is my first time troubleshooting something like this. Same with the second suggestion. Thanks in advance for your time and effort...Leave a comment:

Sound, no picture, back-light is working, no picture with a flashlight, and I've replaced the T-Con board with no change. Any suggestions of what to test or check?
I can add pictures if needed.
