So would this kind. You may be able to get similar-type iron locally at a "dollar" store even cheaper.

Whether iron is shaped like a pencil, a pistol or is a cordless rechargable, the wattage/tip temperature and the amount of time you linger at a joint are more important factors. |

Yeah I know it has been almost a year since this post. I just decided to buy a new TV and am now ready to try to fix the old one. I just opened up and have located one of the capacitors. Not having a trained eye for this I am not sure if anything is wrong with it or not. Haven't located the other one. However there is alot of dust in the tv. Is it safe to vacuum the inside of the tv? Thanks. Here is a picture of the inside of the tv. The magnifying glass is pointing to where I found one of the capacitors. How do I remove the circuit board? It won't slide out. I can see this is gonna be a pain lol.

He's baaaaaaack!
Why don't you just fix the old one and continue to use it rather than buying one of the new "disposable" televisions?
We are talking under $10.00 in parts (delivered to your door). JUST SWAP EM! (observe polarity).
Yes it's safe. Use a VERY SOFT brush attachment. (If you are bending/moving parts, brush not soft enough).
Edit: Should be releases on one side or other (or both). |

| lol Well the new disposable Panasonic 42" Plasma HDTV is a just a tad bit better than this old non-HD CRT lol. I will try to fix this one and give it to my bro. I don't see any releases on the circuit board to move it out. grrr. lol |

I took a picture of the 2 capacitors that are in question. The CR561 is clearly marked but the CR565 which appears to be the bigger of the 2 capacitors across from the CR561 seems to be labeled CR569. Maybe I am reading it wrong. Maybe the 9 is actually a 5? Anywhere here is a picture of it. Tell me if those are the right capacitors. One other thing. I have had the tv unplugged now for over a week. I am not in any danger of touching anything that might give me an electric shock and kill me am I? If so what do I need to do to prevent that? Thanks.

CR569 (aka C569) is NOT used! (I'm guessing hyperactive fingers on the keyboard). You are pointing at the correct caps. Once they are removed from the board, you should be able to see ID better.
Set will be safe. |

| Well I might get out of this cheap. My mom works at a place where they have tons of capacitors for circuit boards. She told me she might have these capacitors at work. She said if I could give her the circuit board she could give it to someone that will test the 2 capacitors and replace them. My question is how do I remove the circuit board? The one thing on it that I don't really wanna touch or deal with is the flyback transformer. There could be high voltage waiting to kick me in the ass. I know you say its safe but I have been reading that you can get a lethal shock from that thing. Should I even attemp to move the flyback transformer wires? Probably best to do it right where it is sitting right now. lol |

I'd just mark the two caps and let the guy test them, but if you insist on removing boards...

Again mark all connectors and plugs so they will be reinstalled correctly (Take photos?). You'll want to remove the CRT socket board along with the chassis. Everything does unplug at one end or the other. |

| I hate to keep harping on this issue but I am gonna anyway. So your saying I should definately check to see if the TV is charged before attempting to replace the capacitors? Before you were saying it will be fine. Well which is it? lol Better safe than Dead!!!! |
