Re: Sanyo DP42848 Has sound/bad picture
Update:
So I ordered 5 replacement AS15F chips. They're still on their way from China, but in the meantime my pops made an attempt to remove the current chip on the T-Con board. Now he accidentally pressed too hard and thinks he's cut some traces and he's not sure which go where (coinciding with the capacitors on the back of the board behind the chip).
Does anyone have a schematic of the T-Con board for this particular model so he can trace the contacts? Please and thank you .

Re: Sanyo DP42848 Has sound/bad picture
That is the same number, however I'm weary on picking up a used board. Price would have to be lowball offer low, as I don't know how much life that board would have left, and I wouldn't want to offend you with a lowball offer as well.
PM me your price as well, and maybe we can work something out....Last edited by Jewcano; 01-04-2016, 06:18 PM.

Re: Sanyo DP42848 Has sound/bad picture
Know of any dealers who sell a new T-con? As I mentioned earlier, seems that most retailers online have used/refurbed models. My pops is good at soldering, but even this chip seems to be a tad overwhelming due to it's small size....

So I went ahead and did the gamma check using the Excel Sheet another member uploaded on here. My results are attached....

Re: Sanyo DP42848 Has sound/bad picture
So we popped the bezel/metal frame off and played with the strip on top. Tapping or touching each ribbon cable did nothing to the picture. The 2 boards ontop did have some 'flex', but pushing them down did nothing either.
Here is the image of the menu.
I'll look into the 'gamma voltage' to check....

TV is at my parents house right now, will update with a menu picture when I have a chance to go there.
The image itself seems overexposed, menu included, but pictures speak more volume than words....

Re: Sanyo DP42848 Has sound/bad picture
It's funny you mention this.
We have another TV we picked up a while ago, and it had a FULL negative picture. However when you'd bang on the top of the TV, the picture would go back to normal. The culprit on that TV was this same long board at the top. We applied a penny, literally to the top, fixed it down, and that tv has been working fine ever since.
Was curious if that same solution would work on this tv, will have to try that before ordering a replacement board. This TV just seemed a little...

Are there any places that sell new? I'm finding on ebay or google "used" or "refurbished".

Sanyo DP42848 Has sound/bad picture
New to this forum, but not to forums in general. I recently picked up a Sanyo DP42848 on the cheap side with a similar issue that I've read on here. I noticed many people had a similar recurring issue "Good sound/no picture". However I didn't quite see anyone that had this particular picture issue. The TV will turn on, but the image is highly distorted and very whitish, almost bordering a negative type picture and the TV has white lines equidistant to one another going across vertically.
We proceeded to pop the back panel off and take a closer look at the boards. We checked...
