I have this tv which has a blinking green light when plugged in no backlight nothing. I have tested the voltages and the standby is 1.5v with mainboard plugged in. If I disconnect the mainboard and inverter I get the 5v standby. what I did was connect a 2.2k resistor between 5v standby and power on, when I did this I was able to get the 24v and 12v with no boards connected(before I did this I had no 12v or 24v). This is telling me the mainboard is at fault. the problem I have is I don't know what to test on mainboard. any ideas would be awesome. I am not sure how to diagnose mainboard issues. used mainboards are around 80 dollars or so but was wondering if I could narrow it down to a cheap component. thanks in advance

Re: Toshiba 40rv525r mainboard???
Does the standby voltage goes up to 5V when the main board is not connected?

yes it does bud. I am assuming its something on mainboard but im not sure what to test on the boardComment

Re: Toshiba 40rv525r mainboard???
You can use 10 Ohms 5W resistor for 1/2A load on the 5VSTBY to see if it will stay at 5V, then use 4.7 Ohms 10W for 1A load and see what happen.Never stop learning
