Man what a learning experience this is.I put new LED lamps in. I cleaned the switch real good with deoxit. I had to bring out the length of the fuse holder. I added a piece of wire underneath the screw and screwed it down tight. Fuse is held very well. All fuses show continuity. I wonder if the resister is not good that is connected to the power coming in side of the fuse? I do get a wierd AC reading when checking it like 5.0 or some such number. I put all the wires for speaker output exactly where they go. I put the jumpers exactly where they go. Would putting new lamps in cause it to not work? I wouldn't think so since it worked fine when 4 of them were bad. I'm at a loss. I appeal to anyone who can help me figure this out. I was so looking forward to hearing some music. Thanks all Cheers!.

So this morning I get up and I think maybe I messed up where the power comes in because I broke one of the clips that hold the fuse. So I bought new clips, carved out a bit of the mount so they would fit and put them in. So now, I plug the unit into my dim bulb and turn it on. I get 120 volts on the top but I am not getting anything from the bottom white wire that goes to the 3amp fuse. I'm also not getting 120volts to the switch or the main fuse. I think the switched and unswitched plugs are bad. It's my guess anyway. I'll have to order new ones if I can find them.Comment

I think I messed up screwing around with the broken fuse holder. What is the purpose of the big resistor attached to the lerft and right incoming power cable? I am thinking of bypassing the switched and unswitched outlets. I have no idea why I'm not getting power. None of the soldered connections are touching the fuse holder although I had to solder the fuse in place. Maybe that is the problem but if I can get rid of all the outlets I can run it straight through the fuse and be done unless the resistir or capcitor whatever it is, is no good.Comment

Sorry for all the posts. I can give you a better pic if you need it. Anyway, I get 120v across the top of where the fuse goes. I get 120v from the right top to right bottom. I get 120v top right to bottom left. I do not get 120v across the fuse or from bottom right to bottom left where the white wire connects to the 6amp fuse. I think this is the problem. Trying to figure out how to solve it hmmm....Comment

Yep! I'm a bonehead. I soldered the white wire to the wrong terminal. My bad. I'll fix itComment

I am Repairing this unit. It had many problems. One major one was the power transformer being about 4-5 volts low on the main B+ line which called for 66.5 Vols after the Main Filter caps but only showing about 62 Volts. Caps and the 5 amp Diode bridge were replaced which helped slightly.
The other strange problem was the small secondary winding from the PT which supplies 18 Volts AC to the "FM FLUORESCENT DISPLAY" circuit, and the small winding that supplies 8 Volts AC to the push button grain of wheat lamps. Those voltages were down from 18 Volts to 16 volts. Which was... -
All,
Some of you have helped me in the past and I am very appreciative of all the help! (I have fixed TVs/Stereos/ and other small appliances with your efforts...Thanks so much!!!
Today I went to a local HAM Radio Festival. It was one of the smaller ones in our area. My stepfather is the HAM operator. I tinker in electronics but am a Software Programmer (27 years now).
I was looking for a few odds and ends for some electronics work I have to do for the household/farm. Typically these type of shows have the grab bags or a electronics vendor... -
Picked this one up today.
In addition to falling LED diffusers there is a single line here that maybe a deal breaker.
From my reading on these boards it is said that the issue is likely a sign of failed tab drivers, ribbons or tab bonding to the panel.
Wanted to get a 2nd opinion from you guys before I gave up the ghost.
Great looking TV otherwise.
Is there any tricks I can do to try to save this one?
If so, i'll gladly order a set of backlights and save this one from the landfill..
Thanks in advance

Hello everyone, I have decided to try and replace the mosfets in my power amp (the one with relay and left and right sides) on my kenwood kr-6030. I'm trying to get the A side of my speakers working. I have replaced all the caps in the power board and I thought why not change the mosfets. They seem to be working since I have great music coming out of the B side speakers and since I am not an electronic guru (but I am learning) I don't want to make any mistakes. The mosfets I have are listed A913 so I guess 2sa913 and 2sc1913. Can't really find those in mouser or digikey at least with the info...

I have two Boards BN41-02568B for a UE55MU6179 of which one does produce a good picture (Board A) but can not save its configuration (even a factory reset will not work) and one board which produces a distorted picture (Board B). Learning from here the IC1604 saves the configuration of such a TV.
Before replacing the IC1604 from Board B to Board A - would that actually solve the problem from Board A not being able to store its configuration or could there be something else wrong with writing to the flashrom? Is it even the right chip to replace or should I look out for a different...
