Re: Panasonic plasma TH-42PZ80U or TH-42PZ80UA, 7 blinks, random green image, questio

Thanks again for all the help. It turned out that it was just a loose connection or something. I decided against ordering parts and reassembled the TV (SD/SU/SC reconnected) as a first test and it worked. I'm really surprised because everything seemed very tightly secured, including all the ribbon cables.

The TV is much happier now that it's all dusted. The fan noise that was obvious has now become very quiet.

I really appreciate all the help. : )

I read somewhere (service guide or something) to leave the set unplugged for a minute to let the capacitors drain but that doesn't seem like it would be long enough. How long should I leave the system unplugged after plugging it in before unscrewing anything?

"Danger, high voltage" makes me want to be certain.

One of the things that made me think there might be a specific SC board for the UA model is that some...

Re: This is Why You NEVER Ignore Bad Capacitors!



I read that the capacitor fails prematurely because it's undersized or the circuit isn't built correctly.

If it's just a case of these capacitors having a lifespan limit then Microsoft should have warned buyers in the manual in a prominent location or, better yet, should have figured out another way to keep time — like a battery....

Re: Panasonic plasma TH-42PZ80U or TH-42PZ80UA, 7 blinks, random green image, questio

Thanks for all the detailed info!

So, the green image issue sounds like it's separate from the 7 blinks issue.

All the part vendors warn to order by part number not by board number but there is absolutely nothing I can find on any of the three boards (SD, SU, SC) that indicates anything other than the board number.

The sticker thing is what makes me nervous because it seems the SC board is specific to the UA and U versions. I don't want to end up getting the...

Re: This is Why You NEVER Ignore Bad Capacitors!

Anyone else take apart a dead XBox 1 to find the design flaw that causes a cap to leak on basically every single one of them, destroying the board in the process?

My spouse's brother had one. It was babied and kept dust-free but there was nothing he could do about the cap.

I am not DIY enough at the moment to deal with testing for voltages with multimeters, recapping/soldering, and such. If it’s really not hard to do, though, I suppose I can go out and buy one. There is a repairman 60 miles away so I can take it to him but I need to know some things to decide if it’s worth putting a bunch of money and time into.

Before the TV refused to turn on with the 7 blinks the picture would randomly turn green or partially green once in a while. Not a “green screen” but television images only with just the color green, or mostly just the...

Re: New Members - please post your introductions here

Hello. I go by my middle name, Aaron. I'm a bit of a computer geek but haven't gotten into fixing boards. I bought soldering stuff but haven't tried it out. I have a Powerbook 540C that needs to be recapped. It still runs but the screen has noise. I also have a Fairchild VES that needs to be fixed. It runs but the video signal is very weak and only appears if you press on a cable. As you can tell I like vintage tech.

The main reason I'm here right now is to get help with a Panasonic plasma television that seems designed...
