Sanyo DP46840 Half Picture Chassis -01

[ntehicks]

I just picked up this TV today. It is a Sanyo DP46840 Chassis P46840-01. the owner told me that when they first turn the tv on the get half a picture. and after about 30 minutes the tv will go to full picture. I wonder if some of the caps on the main board could be the trouble. I have attached some sample pictures. some of them look a little bulged at the top. not sure of this would be a t-con. but I thought it was strange that it would start working after the tv warmed up. any suggestions would be awesome. thanks for your help.

Those caps look fine. You might have an inverter going bad. You also might have a bad panel. I have a DP46848 that has half a picture until it warms up. It has bad tab bonds. Flexing the chasis gets the picture to come and go.

I found that the bonding tab to the screen is not making a good connection. I found a video out on you tube with this exact model of TV. And Wow it was easy to get to this spot. I wish all of the TV were made like this. I added a piece of foam and now the picture stays full all of the time. thanks for your help.
