    Please help me repair shorted out TV power supply

    Two things jumped at me: 1. White residue on low voltage section and to lesser degree everywhere else. Might be water damage. Don't have to be spill - might be condensation. 2. Lots of discoloration - it runs hot! I think most of the caps you took out are from power filter and TV probably...

    Slingbox Pro-HD no so go

    SLM284, I'm glad you are digging knowledge on the Interweb, It will make you only better. But one should not be ignorant to specifics of applying such knowledge to real life. Little knowledge is a dangerous thing! This is very academic description you've found. Nothing wrong with it...

    You've mentioned toneamp. Do you have turntable connected? If so, is it happening when you play LPs ?

    Help needs to identify part. (Small clamp?)

    I'm glad to help! ... just not on the LCD glass. Next to it, like on the frame holding wire insulation, is fine. But not on the glass, not on the contacts! I don't know how hot it gets over there, but hot glue is not the best for the cars. Silicone or epoxy I think is better for that...

    Old computer power supply has low voltage.

    Do not run old PC switcher without load! most of them do have minimum load requirements. At leas load them with dummy load, like 0.5A each. Otherwise it might go into over-voltage. Sometimes there are zenners parallel to buses, they might blow short to protect the rest of the electronics. In...

    Help needs to identify part. (Small clamp?)

    Do not use RTV1. Yours probably older LCD, probably you have Indium tin oxide, even if newer Aluminum Zinc Oxide, regular RTV emanate acid, it might dissolve transparent electrodes. If you absolutely have to - make sure it is RTV2 (neutral). I would advise against any glue on glass, even...

    Slingbox Pro-HD no so go

    Empirical/analytical way... Normally manufacturer will provide reference to parts marks. In this case I don't know who is the manufacturer. Now, you still can find replacement part: As I mention I did measure 2.5A at max load. Looking at Digikey list there are HOLD current ant TRIP...

    Slingbox Pro-HD no so go

    Removal of FB13 should not be an issue, unless you have really pointy and low power iron. I'm guessing hot air station is not and option for you. Wet it with a lot of solder, keep heating both sides while gently prying it with dental hook or small watch screwdriver. It will popup off. Clean pads...

    Slingbox Pro-HD no so go

    oops. Pardon me, just trying to help, my bad, of course it is common mode choke, not fuse. F1 is fuse. I had to spend more time writing carefully. FB13 cooke to x-leaking current additionally stressing F1. Remove and bypass FB13 AND F1. Never the less, my info is good, FB13 is bad, or at...

    Slingbox Pro-HD no so go

    Here is your fix: First change two electrolytic next to switching regulator. they are through-hole. There is a lot of ground around them in led free solder and I believe they forgot to do thermal relieve on their artwork, so you need about 700F iron to get them off. Next - delete and bypass...

    Weller EC2002 erratic temp display on "set" mode

    Definite fix to Weller EC2002 erratic display and no heat. OK humanity, here is my present to you. I hope it will save tonns of collective time tinkering with moody Wellers. As many of you who landed on this page, I have a few of EC2002 inherited from my old job. I love these irons more than...
