60ZT60- green dots, shutting down, 3 blinked once, 8 blinks a lot of the time..

Re: 60ZT60- green dots, shutting down, 3 blinked once, 8 blinks a lot of the time..

Also oddly enough- the screws holding the hdmi board are black, and all the other screws inside the unit are silver on all the other boards...

I am going to the local hardware store to see if I can match up a silver screw and replace the black ones.

Not that I think it will fix the problem, but since I don't know what else to do at this point, it is worth a chance...

I'd buy a can of air,the one you use to blow the dust out of a pc,and have a hair dryer handy.
Turn on tv,be aware to NOT touch anything,high voltage danger!
Take can of air ,hold up side down and spray on areas of mainboard,you will see it freeze.
See if tv reacts to that. Then take hair dryer and heat mainboard,see if you get a reaction.
Logic board can also be a candidate for funny behavior,give same treatment if no reactions from mainboard where had.

The power of pictures,just looked up your mainboard. It be best to try to remove that large metal shield for best effect of the cold/hot test.

Re: 60ZT60- green dots, shutting down, 3 blinked once, 8 blinks a lot of the time..

Screws on the 30 and 50 series are also black ( Mainboard ). The problem you are having is bad bga solder under the CPU of the mainboard. There are tiny balls under that cpu that are all connected to the mainboard. Because of heat some small solder balls got loose which results in symptoms you are having. The tv is detecting a error and shuts down.

The board gets cold again and the solder balls touch eachother again and the tv turns on again. Replacing screws is not going to fix your problem , replace the mainboard!!

Good morning,

Thank you for replying. You are correct- I bought new screws and replaced them- no change.

The unit is now mostly just shutting off and staying off until I either unplug it or wait for 10-15 minutes and it will come back on. No blink codes 99% of the time.

Are you sure it would be the main board? I have read that a faulty power supply board can cause all of my symptoms- green haze, shutting down, reboot, relays clicking.

The main board is not available new- I'd have to find a used one and hope it isn't faulty in some way as well. Is there no way to have mine repaired?

Re: 60ZT60- green dots, shutting down, 3 blinked once, 8 blinks a lot of the time..

Also- just sitting at my desk again right now, tv is off, and it just machine gun fired the relays about 20 times in a row really quickly.

If the A board is the video board and the power supply is naturally the power supply and has the relays on it- I am confused as to how the video board, with the machine off, is causing the relays to freak out? Of course I am not the expert here... just want to make sure I try to find the right part- since I will need to search for a used one.

No pictures as requested. Did you do tests as suggested in post 22?

I didn't take any pictures as everything visually looks fine. I am familiar with what a failed capacitor or bad solder joint looks like. Sure it could still be bad solder, but if I can't see it by eye in person you probably aren't going to see it in a picture.

I am also hesitant to spray a thermal shock onto warm components- especially given that the A board is no longer available- I have to find a used one if I want one- why risk damage to mine which may be perfectly fine. Not to mention the chilling inducing condensation/moisture onto a live board. Doesn't seem smart to me.

There has to be a real way to test, no?

Also- as I already asked- how would a failed video chip cause the rapid fire relay clicking on a unit that is turned off? I've read that the relay clicking, green haze, and shutting down are all symptoms of a faulty power supply.

Real mature responses guys... Seriously?

I asked several times- how would a faulty video chip solder cause the unit to click the relays like crazy when the set is turned off. No one has an answer?

Ok,I'm gonna pretend your not an ignorant ass,as I do strongly feel you are,and explain your mistakes here:

-No pics cause you checked for visual faults already,how would we be able too. Well,could it MAYBE be that by seeing a pic one of us might go "OH wait,I've seen that board before" and remembers the culprit on his.

-Hesitant to try a thermal shock test cause,well,that can't be healthy right? There has to be a proper way of testing this? (as in:not the redneck way I suggested?). News flash good sir: That IS how you test that. The great among us use this method too,like norcal.Wanna call him a noob too?

If you read up about BGA chips,then you know the connection between the PCB (google that too bitch)and the BGA chip is with little solder balls.Also google lead free solder.And how not flexible it is compared to lead solder.
Then use your brain and mix in expansion and contraction of metals under different temperatures and you might come to the conclusion that freezing and or heating the suspect board is maybe not that crazy of an idea.
Also,the mainboard is in control of turning on the power board,does it now click in your head like your power board does?

Anyways,goodbye again....for what I'm concerned you're on your own.

On the internet people show their true personality. You must forgive me for seeing the irony of someone who behaves like that calling someone else an ignorant ass. You wouldn't speak to someone like that in real life.

Hesitant to try a thermal shock test cause,well,that can't be healthy right? There has to be a proper way of testing this? (as in:not the redneck way I suggested?). News flash good sir: That IS how you test that. The great among us use this method too,like norcal.Wanna call him a noob too?

I didn't say redneck or noob- you did. Are you subconsciously self associating? And yes it sounds like a hackjob way to go if you ask me. I doubt electrical engineers at Panasonic are sitting around doing that to customer owned tv's and would frown on the practice.

If you read up about BGA chips,then you know the connection between the PCB (google that too bitch)

Reinforcing my first reply above. Are you 12 years old or just developmentally challenged?

lead free solder.And how not flexible it is compared to lead solder.
Then use your brain and mix in expansion and contraction of metals under different temperatures and you might come to the conclusion that freezing and or heating the suspect board is maybe not that crazy of an idea.

You do realize (maybe you don't) that you just proved my point?

Gee lets take a hot board with a lot of not flexible tiny connections and randomly shock cool them. I can't see why that could harm anything right? And beyond the solder- the stress on the components themselves. And moisture while live??- nah, that could never go wrong.

Anyways,goodbye again....for what I'm concerned you're on your own.

You won't be missed. No loss as you were of no help to begin with.

I do have to say that I am disappointed at this forum though. I was directed here by someone suggesting there are experienced knowledgeable members- instead I get 'google that bitch' boy above puffing up his chest and strutting around as the leading voice. Sad.

Okay guys calm down please or I will start deleting posts and issuing bans.

There is no need to get upset at martino, he may have a coarse attitude but remember everyone is just here to help. Please do remember we are all volunteers and we provide help freely in an attempt to save electronics from the scrapyard. I too use the techniques that martino mentions, as do many professional techs. It is safe enough, provided that you do not overheat the board or allow too much condensation to form. Though failures of processors due to lead free solder are less common nowadays, it can still be an issue that pops up now and again. Another common failure is flash memory, and heat/cold can also reveal issues here, although less likely to be the cause of the issue with your set.

If you do not want to do these tests or are unwilling to do them, I would suggest you find a new A board as that is likely the cause of the fault. Failing that, save up for a new OLED TV.

Your symptoms are the same as on the old playstations with the blinking led , BAD BGA SOLDER! I'll try to explain it once more!

When your tv is turned OFF and the mains are still plugged in then there is always 5v in the mainboard present. 230V ( europe ) goes in the powersupply and ONLY gives 5V to the mainboard.

The powersupply gives only 5v to the mainboard , mainboard "tells" the powersupply to turn on by turning on different rails of voltage like 3.3v for the powerbutton /5VSTB /15V etc. A mainboard with bad BGA solder will act weird and can randomly shut down or turn on the tv. I'ts the mainboard that turns on the tv , not the powersupply. The PS only provides the power to turn on the other boards.

You call it a videoboard , but there is so much more on that board then just video. It has the GPU chip ( probably 2 ) and a dual core cpu.
The cpu and gpu get very hot and eventually it might cause a bad connection between the board and the cpu because the solder came loose , which causes the tv to act weird.

Bad bga soldering will give the following symptoms.

1) FALSE different blinking errors. <- mainboard is confused.
2) Tv will randomly turn off and turns on when it has cooled down. ( solder connects to the mainboard again ).
3) Sparkles on the screen
4) Vertical lines on half of the screen.

A bad powersupply is ofcourse always possible but when the powersupply is bad , it usually is DEAD and will stay dead. There were some small design flaws on older models like the 42PZ80 which had a defective 1uf capacitor but bad capacitors on Panasonic plasma's is "NOT POSSIBLE!"

I am 95% sure that you got a defective mainboard and yes i know your feeling , it absolutely SUCKS to have such a beast not doing anything.

What you can do is the following.
remove the mains and remove the mainboard from the tv ( dont worry you wont get a shock or anything )

Remove the small heatplate from the board , it has small plastic clips that you need to squeeze together.
When you got it removed , get some flux and apply it under/around the CPU and with a heatgun simply reflow the cpu. There are some video's on youtube.

Wait for the board to cool down and reinstall the heatsink/plate. turn on the tv and see if it stays on for a longer period of time.

Good luck and yes pictures DO help!

Re: 60ZT60- green dots, shutting down, 3 blinked once, 8 blinks a lot of the time..

Thank you. I will look on YouTube and try to reflow the a board after I back up my calibration data. Is there any special flux that you recommend, or can I just pick up whatever from the local hardware store?

[Moreno83]

Re: 60ZT60- green dots, shutting down, 3 blinked once, 8 blinks a lot of the time..

Hmm just "no clean flux".

Do you have a heatgun? You can try it without flux first and see what happens.

It is a very common problem with all new tv's.

[tom66]

Re: 60ZT60- green dots, shutting down, 3 blinked once, 8 blinks a lot of the time..

Best to use tacky flux - you can get it from eBay.

Moreno, this fault isn't that common nowadays. It does pop up from time to time, but most BGA problems have been figured out by manufacturers. It's one of those things that took a while for industry to get right. Leadfree BGAs can be reliable, just like leaded, with some considerations as to the manufacturing process.

[Moreno83]

Re: 60ZT60- green dots, shutting down, 3 blinked once, 8 blinks a lot of the time..

Ok my bad , saw alot of sony's and samsung tv's all with bad bga solder.

Why not freeze the GPU first? You could use a can of air and hold it upside down , it will also freeze the board. Dont do it to much though

[PowerDubs]

Re: 60ZT60- green dots, shutting down, 3 blinked once, 8 blinks a lot of the time..

Went to the store- bought a heat gun and 2 cans of air.

Removed the metal cover over the A board, backed up the data onto a USB drive, and am now waiting for the TV to act up- and naturally it is now behaving perfectly. Uggh.

I either need for it to shut down and stay off- not immediately reboot, or do the green sparkle thing while on.

So far- nothing. Which is frustrating because it normally started shutting down fairly quickly once started.

Only thing I changed was the cover off the A board and am running it with the back cover off as well.
