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.

I have a gateway model gtw-p42m102 and there is no picture or sound. ther is a green light in the back that blinks 8 times and starts a 8 count again.


Gateways are an absolute nightmare to work on. Basically, there are no parts available for them, except from Gateway, who used new sets parted out, and they charged incredible amounts for service calls (if you were lucky enough to live in a metro area with a gateway store nearby).

Most shops will turn the away. The Y-sus and X-sus boards are very prone to problems, and unfortunately, are not available for replacement.

I'm sorry to be the bearer of bad news. Especially considering how much you probably paid for this TV. I have a Gateway, but only because it was free, and I have to repair it every 6 months.

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.

Gateway GTW-P42M102 / Won't come on

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
