Hello people ,
I 'm new here and I'm from Germany .
Please forgive me for my bad english .
So now , I have a big problem with this TV !
When I turn the TV on , starts the relays on the power supply to clicking , and the power LED flashes 4 or 5 times , this game is repeated again and again.
I have renew, on the PSU, 2 transistors ( QU 801 + QU 802). After that I checked if all voltages are present. All voltages are there!
Then I found out, in a Russian forum, if on the logic board and PSU bridging of contacts that can leave the TV running in a test mode , it operates , the TV shows some test images (white, red, blue, and a white beam) this repeated again and again. After remove bridging: Clicking again .
Is the error on the motherboard? I checked the voltageregulators on the motherboard , also here are all voltages available! can you please help me? I do not know how I can find the error.
Maybe one of you ever had this error. I hope I finally expressed understandable .
Many thanks for your help .
Klaus
