Question about Sanyo DP46849 46 in. HDTV
I finally replaced the T-conn board because the TV was close to unusable. It slowly became darker and darker and then started to ghost on the right side. The Darkness is kind of gone, but the color and ghosting is still there. I really hope I didn't spend $50 on the wrong part. Any help is appreciated.

The problem is in the power supply! You must replace the capacitors next to Connection 2 (CN2 is the location). Replace C615 16 volts at 1000Mf,C621 16 volts at 1000Mf, C605 25 volts at 470Mf. C632 is fine, leave it, as is. The 605 capacitor (25 volts at 470mf). Looks good, tests good, replace anyway! Now with this complete, resolder all of the transformers (Large and small) pins you can find. Resolder inverter connections CN4 and CN5. Resolder any and all heat sinks (these hold transistors and mosfets). This will correct the dark shadows you see on TV. Thanks for asking, Matt of Martins TV.
