Check the panel voltages, and start unplugging the cables to each PCB and check the voltages each time, if the voltages come back up the its probably the PCB that is disconnected, in most case its the logic main board. Hope this helps

Had the same problem... drove me nuts... I figured what the hell!!! I started pulling boards out, and on the main power board I dicovered a visual indication that one of the main capacitors "M105k" took a ****. Ordered it for $1.29... presto, works like a charm! I had to remove both relays and manually rig them to the on position for troubleshooting purposes. I'm replacing them with new ones. Let me know if this helps!

The menu pops up on starting and continues to scroll. The front panel buttons on the TV do not do what they are supposed to do (i.e. Vol button changes input option, etc.)

i have the gtw-p42m102 and it did the scrolling thing and i had the image board dpwb11393-1g-l changed and it worked fine for 2 years.Now it made a pop like a firecracker and i am working in it now.

Main Power Board

The power supply board can be changed without any knowledge of repair but there are sometimes adjustments necessary if the picture is not normal. Many times it is fine. There a 4-5 voltage adjustments that would take some knowledge and a meter to accomplish. You need to hope it was diagnosed properly first. If it is completely dead the p.s is a good possibility. If it clicks on then back off almost immediately it is not likely the power supply.
