Today when my girlfriend came home and turned on our tv (LG RE44SZ21RD) she also turned on the AV amp. I think by misfortune they both tried to kick in at exactly the same time and drew too much current for our RCD throwing the trip switch.
I switched the TV to off, then reset the trip switch, then turned the TV back on. The tv came into standby fine (red LED illuminated as usual) and when I used the remote to turn the TV on that seemed to work too... The green LED flashed several times then stayed on. However, I get no picture.
Let me stress: The TV does not turn itself off after a certain time or give a flashing amber LED - ie protection circuit is not activated (so as far as the TV is concerned everything is fine).
The problem is that the lamp is not illuminated at all. I decided to check if the lamp had blown by replacing it with one I know works. (I replaced my old lamp when it got to 6k hours despite the fact it still worked - so I used this for a test).
So I guess the next most likely fault is the ballast board. The one in the TV is an OSRAM board - 3757790027. LG part number 6316000002D.
What I want to ask you guys is... is the ballast likely to be the problem? what is the procedure to test the ballast board?
I am a physics phd student so I have some electronics knowledge and have some lab equipment available to me.
