SOURCE: My LG MU-42PM11 popped a fuse on the zsus board. I

Hello again.
In case if you would replace fuse (it's one of two ceramic slow-burning fuses installed in holders next to each other) and it woudn't burn but TV still have no image - that means that both Z-Sus and Power Supply boards are bad. If fuse got blown again right away - usually indicates that Power Supply board still OK and does not need to be replaced.
Before go ahead and order Z-Sus board, visually check out narrow buffer board that attached to it. On other end of it you will see several flat ribbon cables that go into Plasma Panel. Make sure that you will not fined any cracked (exploded) microchips ot other electronic components or burn marks on it. Sometimes short in buffer board can cause Z-Sus short out as well. If everything looks fine - replacing just Z-Sus board would in 95% cases repair your TV.

SOURCE: No picture just sound thru dish network

There are a few reasons that this could happen. The main reason would be that the tv is on the incorrect channel or input. You will want to make sure that if you are at TV1, the channel is on 3 or 4, and an input if needed, such as VIDEO 1 or 2. If at TV2, the channel needs to be on 60 or 73. Cabling is another reason this could be. You want to make sure that if you are at TV1, all cables going from the receiver to the TV are connected on the back of the receiver at the green TV1 location. For TV2, the cable needs to be connected to the HOME DISTRIBUTION output on the back of the receiver.

I have a LG TV 47LD650 that has picture but no sound out of tv speakers. If I connect an optical cable into the output and use a sound bar, will it still produce sound?


You have to go to setting and change the audio output to TV speakers for the TV speakers to work,, but, if you use a sound bar with optical connection...you have to set it also .. mine works the same way,,

Just purchased Rico bos90. Put optical cable from my lg tv to the optical on the sound bar. No sound whatsoever


You may need to configure either the TV settings or the sound bar to use the optical connection. If both have HDMI connections, you might consider that connection method as an alternative.

Sound bar compatibility


Make sure red glow is coming from TV's Opt out cable when TV is on. If it is, it is working. The best solution is use an LG soundbar with an LG TV. There is a differnce in digital outputs and with a "service remote" (used by authorized LG servicers) you might be able to change the TVs factory setting to make the vizio soundbar work. but I think you'll be better off with the LG soundbar.

Try just using the optical cable alone. connecting the HDMI and the optical cables at the same time might be confusing the TV.
