Hello I am hoping someone can help. I have recently aquired the above TV for very cheap and I am hoping I can fix the problem myself, but I have never done anything like this before :0) My new little project! The TV keeps switching itself off into standby mode after about five minutes. It is very eay to get back on but will go off again very soon. Also when tuning in the best picture to say the least is very snowy. I have entered the service mode after a bit of research on the net and come up with the error code of 5 11 0 0 0. Any ideas of where I go from here would be of great help. Please remeber though I am a novice at this kind of thing and will need it explained in the best possible laymens terms!!! Thanks you.
Problem is build up on the cathodes and when the reach maximum temperature they cause a short between heater and cathodes .also possible g2 and cathodes short circuit.One way is to separate the heater circuit H1,H2 and use a transformer or build a coil on the line output transformer (3 times not shore read up for it) and u will get 6v for the heater.Read this http://www.penders.cwc.net/otcolour.html it will help even if is for other problems. Good luck
