Hello everybody!
My friend gave me a broken Phillips LCD TV (37pf7320A) and I am trying hard to fix it.
When I plugged it in, the TV clicked, the green light came up and after about 5 seconds it clicked again and the red light blinked several times. That was it.
So I decided to replace all suspicious capacitors in the power supply. I replaced two 2200uF, five 1800uF and one 1000uF capacitors.
I also noticed, there was a crack in the lower right corner of the board and I repaired three damaged traces.
So now, when I plug the TV, it selfchecks all right (it clicks, green light comes on and then clicks again without any red light). Then, when I try to turn it on, it starts with sound but no picture and after about 10 seconds the TV turns off with red light flashing rapidly. It is unresponsive after that, unless I unplug it and plug it back.
Does anyone have any advice on how to proceed? Can the problem be somewhere else than in the power supply board?
Any suggestion would be very appreciated!
Thank you very much,
