But no real big deal to take the back off, replace the screws with the suggested set, and put the back on. Buzzing is now completely gone, it's near silent.


My Plasma just started buzzing today, can you use any lock washer? Or should I just try tightening them first?

I've had great luck just tightening them. Just tighten evenly and recheck.

The Panasonic replacement screw kit was cheap. If you can afford a couple of bucks, I'd go ahead and order it. Otherwise, yes others get along fine with just retightening what's there periodically.

The weak metal they are made of are just wanting to break apart and they won't loosen at all. I got all of the other screws off easily though. Anyone else have trouble with these? Am I doing something wrong?

EDIT: Of the 10 little screws, I got all but 2 off with the help of some valve grinding compound which I should have used to start with. The heads of last 2 screws are almost completely cammed out though. I think I'm going have to use a dremel to make a new slot in the heads.

Anyone know the replacement part number for these little back panel screws?

I finally got those stripped back panel screws off with a pair of screw pliers. I switched the screws out on the boards and the buzzing is much quieter now. Sure enough, a few of the screws on the boards were loose particularly where the buzzing was coming from.

I now can only hear the TV buzzing within a few feet of it. Before it was so loud I could hear it 25 feet away.

If anyone else happens to strip the little back screws like I did, these screw pliers worked. It still took some effort to get them to grip on the screws due to how soft they are. I can't believe how much Panasonic cheaped out with the screws on these TVs. At least it's fixed. smile.gif

Is it possible to update the youtube app on the tv? i really like the new features thay have now on youtube.

Thanks
post #8376 of 8439
The only updates will be from Panasonic and they usually quit before the end of the product cycle, so pretty doubtful. I'd recommend a standalone player or of course a computer of some kind. My two stand alone players, Boxee and Aios, are Linux based and there's some web based videos they won't play. So my solution was to run a 25' HDMI cable from the main PC in the next room to my AVR, that works very well.

I'm currently using a ps3 for youtube videos, that was the easier way out of this. You can update apps on the ps3, this worked for me.
post #8378 of 8439
sry for the double post but need advice tongue.gif
I have a tc-p60st30 and two weeks since it makes the buzzing sound, and now I've noticed that in Commercial there is a small white green line to the left of the screen and at the top, this problem also returns with the PS3. I've seen a picture of this problem on this forum but I am not able to find the post.é
Someone to help me?
thank you
post #8379 of 8439
Hey guys,

I found one of these for a really fair price locally. However it is used and a a May 2011 build date. I presume the FBr hasn't been fixed. Is Panasonic still standing behind the sets? Will it matter that I'm the second owner?

Thanks
post #8380 of 8439
You should be able to download a firmware fix to deal with that

Ok great. I was reading the thread and it just became overwhelming, and as far as I had gotten, it seemed that only techs could install the firmware update for you. I then googled,but Panasonics support area doesnt mention a FBr fix in their latest firmware update.


Thanks for the help. From what I can tell, the only other issue with this set is the screws that come loose, but thats a pretty easy fix IMO. Although, I am a little hesitant. If the new 55" ST60's are pushed out the door to clear out all the old Plasma stock for ~800 bucks during the xmas season, I am probably going to be upset I didnt wait.
post #8382 of 8439
The initial fix was a board refresh but later on the Panasonics shipped with the firmware fix installed.
post #8383 of 8439
There were two fixes for FBr, one was the board replacement and the other was a Panny rep(not a tech) installed new firmware. The Firmware patch had unencrypted software on it so that was limited to district reps only. No chance of downloading that from a site. The only way to fix it is if you have a warranty, big maybe if they will, or just buy a new A board, should be updated already. Not sure if a warranty will transfer to a second owner.
post #8384 of 8439
So you can download firmware and fix it, or you can't? Does anyone know for sure?

The current owner called Panny and they claimed he could download it and put it on a SD and upgrade the firmware with a fix.
post #8385 of 8439
The later pannies shipped with the update so I don't see why it couldn't be downloaded
post #8386 of 8439
I think the two fixes were EPROM board update and later firmware it was the EPROM update that had to be done by the panny rep

This is what I found. This user seems to post in this thread under the same name: http://www.**************.com/showthread.php?t=9631&page=295&p=277047&viewfull=1#post277047


According to that, there isnt a firmware update.

I'm thinking of picking up the Sonos Play 1 speakers to add to my soundbar so I have surround in my living room. They are a little more affordable than getting Play 3 and are much smaller. The question I have is does anyone know if the optical out puts out a DD 5.1 signal? I would hate to buy these speakers to find out that they generally would not have true surround or if the Sonos creates a matrix sound to the back speakers (prologic).

If anyone has any insight I would appreciate.

I ended up buying the Play ones and used a DTS bluray and surround was coming from the speakers. Looks like Panny came through and outputs 5.1 through the optical out.

Hello Everyone and thank-you for your help.

 

I've been straining my creativity to the limits to figure out what went wrong with my tv.

 

I've searched 20+ pages of posts and didn't find anyone with a problem exactly like mine so I'm posting here in hopes I'm not beating a dead horse.

 

My TC-P60ST30 has been a faithful tv for 2 years now.  I had no problems and enjoyed the quality picture.  2 weeks after my extended warranty was over the set started to develop a buzzing noise which gradually escalated into a buzz so loud I could hear it from any room in the house and watching the tv was impossible if I also wanted to listen to people talk.

 

My dad is an electronics technician.  I grew up playing around his shop.  I think I recognize the sound of a failing power supply, but the internets say that it's just a loose screw problem, and I'm happy to hope it's that simple.

 

I removed the back panel and tried tightening every screw there was to tighten.  Only issue....they were all tight.  Next step I figured I'd remove the power supply boards and see if something failed.  After a careful inspection (finding no issues with sight or smell) I put the entire thing back together and tried turning on the panel.

 

It would not power on.  :(  No red light....no noise.  Nothing.

 

After re-examining it I found I forgot to re-connect the small 5pin (P63-P64) and 6pin (P61-P62) wires to their connectors.  Oh well...no biggie.  Plugged those in.  TV still won't power on.

 

I've tried everything I could to deduce what was happening.  I would hear the faintest of (one) clicking noise upon power plug connection; but no other signs of life.

 

I dug out the multimeter and tested the boards.  Power supply board 5 gave power to board 3 and after that I don't know where it went.  The power button won't do anything.  I even tried connecting the two wires that lead to the power button.  No go.

 

All sleep deprived my probes slipped from my hands on my 3rd or 4th read of the AC current and BEHOLD!!! There is light and signs of life....for half a second as I swear and realize I just shorted out the input panel.  

 

I buy a new panel on ebay.  In fact I buy all 3 of the power supply boards.  Plug/screw them all in and hope for the best.  No response from the tv.

 

I'm about at my wit's end.  Do I suppose the A/V board (with all the hdmi and A/V plugs) is bad?  I read somewhere that it could be the cause of my problem.  There's several on ebay....but is it really my problem?  Can I save this tv???

 

HELP!!!  

 

...please?

Hey guys, A month or so ago my TV(55st30) went out during a lighting storm, but the lights only dimmed. I turned the TV back on and all was fine. During the next few weeks I ran into trouble with my receiver where it was having trouble connecting to HDMI1 on the back of the TV. I changed the output to 2, and still had an issue. I changed it to 3 and it was fine for the time being. A few weeks later The TV would drop signal or show the while and colorful dots like it was a handshake issue, so whenever I unplugged it and plugged it back in it was fine. Now it has gotten to the point where if I just move the HDMI cable up a bit in HDMI3 it will come on. This is a 75ft long monoprice 22?(gauge HDMI cable that is thick and heavy), Still the HDMI 1 and 2 don't work at all. Going through all this I found out that my HDMI Out on my Pioneer receiver is shot, so thinking it would be a good idea I took the cable box out of the rack and put it under the TV with a short HDMI cable, and that doesn't work in HDMI 1 and 2, but when I put it into 3, It shows picture but every few seconds it will do the white background with dots all over for less than a second then go back to showing correctly. It doesn't have a pattern either. I can take a Youtube Video of it if needed. It feels that the cable locks in but there is still some play when it is fully connected in as if I move it around it does seem to change how good of a "reception" it is getting. Any help would greatly be appreciated. Anyone know how much it costs for the HDMI board for the 55st30?

An update to this, I was testing it with the comcast HDMI cable it came with, and that "static" was showing, once I changed it to a Monster cable I had laying around it worked perfectly. The other ports still don't work though.

Finally discovered the problem with my tv. 

 

I decided to trace the power button wire and to do that I needed to remove the stand support structure.  I found something interesting...

 

http://s22.postimg.org/fxgfbky6p/Where_the_piece_fell.jpg

 

WTF?   I did some sleuthing and discovered that the piece had simply fallen off when I removed the board.  I'm not sure if it was never quite clipped in all the way, but for whatever reason it prevented the power relay to turn on.

 

http://s24.postimg.org/xx4hohvg5/Piece_that_fell_off.jpg

 

So I plugged it back in and everything turned on!!!  And since I replaced the power supply boards the annoying buzzing sound disappeared. 

 

All is well.

HI folks,

Can anyone tell me if there's a fix on the ST30 being able to play back native 2.35:1 aspect ratio external files without it stretching it? I don't have a problem with these files on my Samsung F8500 direct or my Oppo player. Thanks in advance.

Hi everyone, I picked up a 65" ST30 out of the pawnshop a couple days ago. Cost me $1200 out the door, not bad for Canadian prices considering 65" are still not cheap with 3D. I was told it sat for a year so it has a years use, but who knows. Everything come with it except the manual which can be downloaded.

I don't have any buzzing issues. It's a May 2011 set. I have the WOW disc, but haven't had a chance to play around with it yet.
post #8399 of 8439
Hey do you guys think it is worth upgrading from TC-P55ST30 to a TC-P65VT60 ? I'm really not sure if I should or not. I don't need to upgrade but being this is the last model of the Panasonic's and a little bigger TV would be nice I'm really thinking about. Really the TC-P55ST30 is still a nice TV so I'm not sure. I'm wondering if the PQ will be a lot better or not.
post #8400 of 8439
It's a pretty large jump, I went from an ST30 to last years VT50 and night and day better. The contrast ratio increase is huge and the blacks are much better. If you have the financial resources I say go for it !
