This is my first attempt at something like this so please pardon my ignorance.
The original symptoms: 37MF231D/37B (2007) originally already refurbished began taking noticeable seconds longer a few years ago to power on. More recently its been taking 4 minutes to 10 minutes to turn on so i took it apart.
I learned the stem of the problem from googling/youtube-ing which is apparently the (2?) bulging caps shown below. My question is what is all the goo that surrounds not only them but some neighboring parts--some of which are pretty far away as well. Are the orange coiled parts also damaged? Could removing that be enough of a fix so that i dont need to buy a soldering kit? Was it put there by the original refurbishers?
Any suggestions or advice is much appreciated!
I would not worry about that.
The orange coils look OK.
The bad stuff is the blackish junk leaking from the bulging capacitor.
You will need to replace both bulging capacitors.
Be sure to use 105C low ESR capacitors.
If you have not done any soldering/desoldering before, I would recommend finding someone experienced to do it for you.
Also, the big black capacitor (180uF 450V) is capable of storing a lethal charge.
Make sure it is discharged before working on the board!
Generally, there is a bleeder resistor that will discharge the capacitor over a period of minutes but rarely the bleeder resistor can fail.
Still, it is a good idea to check the high-voltage capacitors before working on a board.
