Hey there fellas. First time poster here but a bigtime lurker since a week ago when I got this tv from my uncle.
First I want to describe the problems, which are somewhat random.
In the beginning the tv works fine, but the sounds starts to crackle when it heats up which led me to unplug the speaker wires and use an external audio amp, but just a little while after that I notice the screen flickers terribly when there's too much white in the picture, eventually if I don't lower contrast and brightness the whole screen turns white and stays like that until I turn off and on the tv.
A while after that I started having problems getting it to turn on again, the blue led was lit constantly and it tried to start up when I pressed the remote, but went back to standby. Eventually it would turn on and work fine for a while until I had to start it by remote again.
Then came the flashing led problem, where it got stuck until a random time had passed. I could try starting with the remote or powerbutton but nothing helped.
At this time, I came to the forums here to search for help and found many and interesting answers and ideas. My own ghetto solution was to unsolder the 15nf1000v polypropylene caps (correct me if I'm wrong somewhere) then solder some long wires there, so I could glue the caps to heatsinks to keep them cool. This has helped quite a bit with both the white flickering and the stuck in flashing led problem, but it still turns off to standby mode occassionaly.
If I let it sit for a little bit I can start it again no problems, but the fault is persistant.
I know I need to swap some parts inside, definitely the 15nf1000v ones, but I wanted to ask here first if there's any more perticular parts needed as I'm on a very very very tight budget, so buying a new PSU isn't optional (I'm looking at you tom66 )
I don't have the gear to check if the 330v at supposed 390v problem exists in my tv, but I wouldn't be surprised if it does.
Thanks for reading all this, I hope it can help you to help me, anything from ideas to concrete evidence is helpful, I'll keep my soldering iron warm until then.
