I'm going to spend $20 on a case and that's considered stingy.
Previously I spent $30 on a spoilt NAD 3225PE
Case, transformer, knobs, pots 'n' all, plus precut holes.
Then I spent $40, and lots of time, to repair it.
I could've just spent a bit more money, buy a new working amp board, and put it inside.
Unless one can convince me that that thing repaired is worth $300, there is no point. Since, the Sure, after a bit of modding, does call $300 for a finished product.
That's why some things are just not worth repairing.
So that's part one of today's entry.
Onto part two
My house's LCD TV was acting up right after its warranty period of one year. The symptom of unable to power up right after the wall socket is switched on indicates a failed cap - what I deduced from experience with many cheap computer PSUs with this problem.
Taking the thing apart finds me a bunch of TEAPO (read as CHEAPO) caps, with one slightly bloated.
Another angle.
As I was ordering some things from Farnell I "tong pang" the caps with them - Panasonic M 1000uF 16V (to replace the original 10V; I bought over to increase reliability) and 1000uF 35V.
Turns out the original TEAPOs are rated 105 degrees while the Panasonic M series is rated for 85 only, with this in mind I decided against replacing all the caps until necessary. But knowing how TEAPOS fail when exposed to 60+ degrees inside computer PSUs anyway, I decided the Panasonics are still more reliable.
Then I also learnt that I should've gotten EPCOS MKP over WIMA MKS4.
Nvm, I can use all these caps for future small things.
Replacement part: $0.78
Knowledge to take things apart and analyse: Unmeasurable, but not a lot
LCD TV when I paid for it: $700
Revenue of entire industry operating in the conspiracy of ensuring things break down right after the warranty period thus forcing you to buy a new one: Priceless
There are some things money can't buy
For everything else, there's
PayPal
Which requires MasterCard.

Nice, you are getting the hang of "advanced" blogging. Good use of visual materials and humorous writing.
