Zenith LCD TV Z23LZ6R Sound Cuts Out

Ran into the same problem with this DVD player and my LG tv. Try this:
Open the DVD tray, with the DVD tray open press the HDMI select button until the proper resolution for your tv is illuminated, put the DVD back in, close the tray and try again. Simple fix -- worked beautifully for me.

Good luck

Hello everyone... My Zenith TV popped on 5/5 (popped was the sound it made before the screen went black with but still had sound) and I wasn?t sure what to do. I contacted LG/Zenith to find an authorized repair shop (5/7). Figuring that this all I would be contacting them because the TV was out of warranty. I took the TV set in to get fixed (5/9), I was lucky to find a place that didn?t charge for the evaluation even if I didn?t get it fixed there. They called me a few days later (5/11) to tell me that the Y-sustain board had failed cost around $400 and labor was $225, a $625 dollar fix. I tried to haggle with there marked up price for the board but no luck there he told me that they usually only mark up 10/15 percent on replacement parts and couldn?t knock that off because I didn?t buy the TV there and that there labor was a standard $225 no matter how quick the fix (not that this is an easy fix because I have no idea). So reluctantly I authorized them to continue with the fix. They called Wednesday (5/16) and told me that I could pick it up anytime and was working beautifully. I nervously called Zenith late last night (5/16) 1-877-9zenith(1-877-993-6484) to talk to about the warranty, because I saw someone else here had a little luck with this. Even though my Zenith TV is out of the 1 year warranty, I told them, that they had told me, they were going to cover it under the LG 2 year warranty. Even though they never said this in the previous call, he could only find a record that I had called. I told them about the other people who had the same problem who had theirs covered and had posted on web that LG/Zenith covered it even though it was out of Zenith warranty date. After they put me on hold for a long time, he came back with a contact and a fax number for them to send in the paper work so they could look at it. I contacted the repair shop (5/17) and told them that Zenith was going to cover it under the LG (2 year) warranty and he thought that this made sense because they are the same. I gave him the contact information and he made a few calls to the warranty department or the company that covers the warranties for LG or Zenith (I am not sure about this part of it). He couldn?t get a hold of the exact contact that I gave him because it was only a first name and fax number but he did get a hold of someone else that could help. He told me that they were going to cover the parts under the LG warranty but they weren?t sure about the labor and they were going to call him back. He also told me that I shouldn?t pick it up or do anything until this was settled and that he would call me back. He told me this because he didn?t want me to pay for anything; he has heard that it is very hard for consumers to get reimbursed after the fact for warranty work. I was fine with this since I couldn?t pick it up until tomorrow anyway. He called about a half hour later and told me that they were going to cover both parts and labor for this. He also told me that some of the repairs done on other earlier TVs might have been done before the new revision of boards and that might be why they were having the same problem again but wasn?t completely sure about that. He just wanted to offer his conclusion to why the problem might be happening again. Well take from my story what you will, but I figured that I would just post it for everyone to read. And maybe this will help someone else? -jkt

I would suspect bad solder connections allowing a ground to "float" It is a common problem with the model P42W24BX which I believe uses similar circuitry as your model. An experienced repair shop should be able to get you fixed up.
