greetings colleagues I have this sharp LCD tv model LC-32M44L which does not turn on only the standby green LED flashes, I presume it is some of the lamps this has U-shaped lamps in total 10 press the input sequence and vol (-) to can turn it on but only the image appears for 2 seconds and it is difficult to detect if there is any lamp that does not turn on, my question is if any adaptation can be made so that the TV does not protect itself. in advance thank you for your contributions

Generally when the ignition is forced, as you do, the TV does not turn off when there is a defective lamp, that allows you to verify the errors and erase them, or check the errors at another stage.
If the TV is turned off forcing the ignition, I am inclined to think about a failure in the mainboard, and not in a lamp, I have solved many with this problem, with a reflow in the micro, it also verifies the voltages of the source that do not have riple by some defective filter .... greetings.

When the TV turns off, it counts the flashes of the LED, this indicates the possible cause of the problem.
