Re: Identifying TV capacitor MMKP82 683K630
Yeah that is what I was think too, also after replacing the lamps if I had to then replace the inverter I also then might find out I still have problems with the power supply!
It is like a catch 22, before I would buy any parts I would want to know the new part would fix the TV but I would have to order the part to know it would fix the TV.
With this old of a TV I don't want to spend any more money on parts then I have too. If I had to buy 12 lamps and then fix or buy an inverter and then a...

Re: Identifying TV capacitor MMKP82 683K630
No, before I seen the lamps I had thought about doing that but now that I've seen them I know if I was going to try and fix the TV I would just go ahead and replace all of them even if some of them worked but looked bad....Leave a comment:

Re: Identifying TV capacitor MMKP82 683K630
Is that normal, do all lamps all go bad at the same time. It looks like they were getting very very hot almost to the point of catching something on fire! The inverter board seems fine from what I could tell.
Well it seems you need to have good CCFLs to really know your inverter is working and you need to have a good inverter to really know the power supply is working.
Whos idea was it to put the inverter board inside the display, didn't they think someday somebody might just want to...Leave a comment:

Re: Identifying TV capacitor MMKP82 683K630
I'm not sure that I didn't mess something up and I know I left fingerprints but I took the display apart. None of the lights look good, they all look like they have been trying to catch fire and burn into at both ends.

Re: Identifying TV capacitor MMKP82 683K630
My meter is basic (only thing I could get), reading the meter specifications: 40~400Hz response, 600V maximum input voltage. What type of meter do I need?
Backlights have always come on for a few seconds and shows a blue screen with Element Electronics and then most of the time goes to black, but sometimes would be able to see video and/or menus for a few moments then go black. I sure thought it was blank and black before I put the TV back together.
My pictures from before I removed...Leave a comment:

Re: Identifying TV capacitor MMKP82 683K630
So should I be able to get a voltage reading on VBL+ on connector four (CN4) if it is the inverter board or ccfl lamp?
On connector four (CN4) what does +5VMCU, CNT, PT, IS1 and IS2 mean ?...Leave a comment:

Re: Identifying TV capacitor MMKP82 683K630
UPDATE: I put the TV back together last night and I did the flashlight check again and I can see video, the screen still lights up for just a few moments and then goes to black but I can see video with the flashlight. Maybe it is was too light during the day for me to see the video before because I checked at night this time.

Re: Identifying TV capacitor MMKP82 683K630
Thanks for the quick response and information.
Do you know who makes that capacitor, to the left of the MMKP82 is <> so it looks like this: <>MMKP82.
I don't know if its bad or not, but the capacitor (C142) next to it seems bad to me because it will not take a charge and they are both connected to the same inductor (L11) as you can see in the links to the [B]LARGE[/B] pictures at shopjimmy that I posted in my OP, so I thought I would be ready to replace both of them.
The power board...Leave a comment:

Identifying TV capacitor MMKP82 683K630
[B]I didn't want to bore everybody with a long post so below I listed the short of what I'm asking, but I also wanted to provide details in the long below. Thanks[/B]

I need help on identifying and replacing a capacitor and also finding if there is a way to test it in circuit.
I am looking at a capacitor that is a little gray box, on top of it is written:
MMKP82
683K630
And what does +5VMCU, CNT, PT, IS1 and IS2 mean?

Re: New Members - please post your introductions here
Hello, I come across this forum while searching for information to fix things. I am so glad to find a place where it seems people have a knowledge of electronics and the posting I've read so far don't just say replace the board but give advice on how to find what is causing the problem.
I think this forum is a great resource of information and I hope I will not post any questions that seem too basic in nature and I also hope that someday I might have the chance to help someone along the way.Leave a comment:
