Sanyo DP46849 No Image

[Hearse]

I have a Sanyo DP46849 that I recently got from a buddy that replaced it when it stopped working. When I FIRST plugged it in, the image came up and displayed for a minute and then now, when you turn it on, the GREEN LED turns on but thats it. Nothing else. The problem seems similar to this post, but there was no fix... Visually the Caps appear ok. I have a DMM what/where should I test?

The pictures are the highest RES I can do with my camera. If you need closer pics of certain areas I can try that.

We need a good closed up of the connector so we can read the voltage labels on those pins, take pictures at both top and bottom of the board. Right now the standby power supply is working. We are looking for the pin that is labeled with PS_ON, or PWR_ON.

Re: Sanyo DP46849 No Image

Thanks for the reply. There is a PS_ON/OFF, its the bottom pin on the connector. Here are pics with and without flash.

Its giving me an error with the manage attachments, I put them on photobucket for now.

Thanks, see waht I can do.
Please post the pictures using attachment function in the "GO ADVANCED" button. instead of pasting.

Re: Sanyo DP46849 No Image

Sorry I did not read your comment about the error, so look and see if you have 3.3~5vdc on that PS ON pin. You may want to read my guide to get some basic ideas also.

I prefer that you do not post inline for many reasons. After 5,000 posts of helping others, it matters.

I edited it, I didn't even think about the size restriction, I took the pics in my 1st post with the same camera, some how the resolution changed. Sorry, I edited the original

Is this with you trying to turn the TV on/off? If not, try pressing the power on/off button to see if the voltage changes.

Sorry, I edited the original

Thank you. It is appreciated.

Now we need a clear picture of the main board.

Re: Sanyo DP46849 No Image

Actually, I just went back to my work bench to take the pics, I guess I left the power button pushed... The TV is working, no joke. I just hooked a PS3 to it and its playing a bluray for about 5 mins now. Maybe I just had a lose wire. I will let it play for a while before I confirm its "fixed"

Re: Sanyo DP46849 No Image

TV is still going, I turned it off and back on, everything seems ok right now...

Re: Sanyo DP46849 No Image

Well, at least now you know which signal to look for when it stops working again. You may want to take some voltage readings so you will have something to compare with when it stops working.

Is the sequel any good? I bought the first one on blu-ray when it went on sale.

Re: Sanyo DP46849 No Image

Turned it on this morning, still acting "normal" What voltages should I test just for references?

The sequel is decent (thats on netflix) I liked the 1st one better, personally.

I would get the readings for every pin on CN2 and CN7.

When I press the power button the green light comes on for a few seconds then turns off

Re: Sanyo DP46849 No Image

Checked the fuse and it is good

No 5v at all

Re: Sanyo DP46849 No Image

Please post the pictures of your power supply board, and closed up pictures of the connectors so we can tell you which pin to check first.
You can read my basic guide also.
We need to do some basic Voltage checking first.
