Re: New Members - please post your introductions here

I am a retired Electronic / Electrical Tech with mostly industrial experience. Really enjoyed machine control with relay logic and PLCs and PACs. I can not remember the name of my first computer (senior moment) but I do remember it was tape dependent. That led to a 286, 12 MHz in turbo mode (IBM Clone) and was excited when I was able to purchase a math co-processor. I am jack of all trades and definitely master of none but I try to fix everything myself and usually succeed although I may wear it out taking it apart and putting it back together. "If at first you don't succeed". My most recent project was doing a bottom job on my boat, a 1980 Sea Ray 270 Sedan Bridge. I still enjoy piddling with electronic projects and have many on my list to do.

Re: New Members - please post your introductions here

Hi, my name is Vince. I've been a computer buff going back to the commodore 64. Had a PC Jr. and Apple IIe back in the 80's. I've built several PC's for myself and the kids over the years. I'm a die-hard DIY guy from automotive, to household remodeling. I've had to repair a couple of LG LCD TV's due to bad caps in the power supplies. These were a piece of cake after researching the problem on the internet. I am an engineer, not a technician, but have worked on a lot of electronics over the years. I don't know all of the terminology.

My current problem is also a case of bad caps I believe. I've got two dead Dell Precision 470 workstations. Both have dual processors. Neither will post. After reading the threads in this forum, I tore into both machines and PSU's. One of the PSU's is pristine inside with no bulging caps. Both mobo's have some bulging caps in the area just in front of the CPU's. I have not yet pulled the boards out of the chassis's.

My questions:
1. What is the best way to test the PSU's for proper functionality? When I jump the green wire to ground I hear the relays in the PSU engage but no fans with or without the case switch on the side of the PSU depressed. Should this be 5V dc?

2. Which caps on the mobo are usually the culprits?

Any help would be appreciated

Hi Everybody! I am Kaarigar and I am here to help fix my TV. I don't think I am an expert enough to do component level digging - but I hope to at least learn something here!

Re: New Members - please post your introductions here

Hi there. I was drawn into this site in a search for information regarding an issue affecting a TV in my garage. Seeing the in-depth description and help from the senior members, I figured I would join and post my issue/story.

I work as an analyst by day and enjoy cars, welding, and fabrication in my off time.

Thanks for putting together this resource and, hopefully, helping resolve my unfortunate issue which will allow me to get my TV back online.

Re: New Members - please post your introductions here

Hi all, I am new to the forum and found it very interesting. I'm from Mexico, took almost 12 years in the repair and have it clear that there is always something new to learn. I hope to help and learn from the community. Have a nice day

Re: New Members - please post your introductions here

Hi all,

My name is Sebastian, from the Netherlands and a few days away of reaching the age of 37

As i am not an electrician or mechanic and refused to pay a mechanic for my 2 year old 3d led tv (as i refused to pay a mechanic for my motorcycle flued change), i started googling and then found this forum.
My tv was turning on and off and clicking so i got to this thread : https://www.badcaps.net/forum/showthread.php?t=33767

This really helped me as "electric amateur", i think i have found and thus repaired a bad solder.

Many thanks to the ppl on this forum.

I'm not sure if i return soon but surely will return on new electrical issues !

Cheers,

Sebastian

Google search for my Motorola LCD 42MF437B brought me here. Didn't let any smoke out, but whilst watching US Open tennis heard a distinct click and both sound and video went out and power led turned red. Not about to spring for a new TV just yet, so You Tube DIY was my first stop, which led me here. I'm juyst slightly north of 70, first computer experience was with PACE analogs at NASA working summers on my way to BSEE. Then some smaller chopper-stabilized tube-type analogs and eventually DEC PDP stuff. Owned a couple original IBM pc's and a couple Compaq luggables, and still have my original Norton Utilities on the 5 1/4 floppy. Propbably build 25 systems for the kids and myself over the years. Maybe twice that, actually.
On this project, I Recapped the 3 1500uF C951,952,952 without success, now on to the diodes.

Greetings to everyone, and thank you for allowing me to join the forum. I have some electronics background from way back in the vacuum tube days. I am hoping to find some information about capacitors that are used in PC power supply units.

Hi to all members!

I'm into all things electronic. My first pc was an msx
My first BASIC program was a drawing of some sort of car.

This forum looks brill, can't wait to suck up some more knowledge and perhaps even help out from time to time.

Re: New Members - please post your introductions here

Similar to Fizzycapola's post, I also started with an overpriced first generation IBM PC without a harddrive. I purchased memory chips removed from mainframes.

I use my Mech Engr degree to repair my own equipment. I am now working on my Vizio L32 HDTV10A with a bad power supply. I do not see any bloated caps. I am trying to figure out how to manually turn the power supply on in case the power button or remote control is bad.

I am looking forward to sharing info on this website.
