Cable Repair
I have a broken connector (believe it's a 6 pin mini-DIN) on a cable. The metal shroud and all but one of the pins are separated from the cable, and just stuck together for the photo. The other end is an unknown rectangular connector. The cable is for the foot pedals on an Italian made electronic piano, and the company is out of business. Looking for ideas on how to fix it. I have a soldering iron, but I'm not very skilled at soldering, so getting a retrofit for the broken end may be beyond my ability. The other end would be easier to replace, if I could get a mini-DIN cable with the same number... -
Re: Samsung UN46EH5000, No Backlight
[FONT="Georgia"][SIZE="3"]Great idea, and another use for a heat gun. I will have to invest in one of those sometime.
In the end though, I chose to trash the set, and buy a new one, with a 3 year extended warranty. It just happened the store was clearing out 50" Toshibas, and I got one for $250 (which has been working fine for the past year).
Could I have fixed the old one for less? Maybe, maybe not. But finding a good deal on the right LED strip was difficult at the time,... -

Re: Bad Receiver?
I don't see how it can be a matter of adding a pre-amplifier at the antenna. I've thought of that. But it's not like there is a weak signal, there is just no signal at all for about 10 stations, all of a sudden. They were working for several years with the same antenna I have now, and now they are not. FOX, the most powerful station is 1000kW at 38 miles away. I should get some indication that that station exists, but I get static. That's why I am questioning the tuner itself.Leave a comment:

Re: Bad Receiver?
Never mind, I figured it out. There are no firmware updates at this time. I'll try the factory reset, and let you know....Leave a comment:

Re: Bad Receiver?
No I don't, but I've been looking for a cheap used one, at the thrift store, just to use as a test unit....Leave a comment:

Re: Bad Receiver?
I thought so. I've always wondered about that. Thanks for the confirmation. But no, I have not tried a factory reset or firmware update. How do I do either of those?...Leave a comment:

Re: Bad Receiver?
BTW, from the day I bought it, it didn't get as good reception as the TV it replaced.Leave a comment:

Bad Receiver?
I have a few month old Toshiba 50" flat screen LED, that I have connected to an OTA antenna. It was working fine, but recently it stopped picking up OTA signals, on all but the absolute closest station (like 11 miles away). There was a power outage around the time is stopped working, but that has never affected any TV I've ever had before. The antenna is in good shape, solidly connected, so no problems there. Could the receiver be partially burned out? -
Re: Samsung UN46EH5000, No Backlight
[FONT="Book Antiqua"][SIZE="3"]No. I tried to remove one by heating with a soldering iron, but when I tried to remove it, the LED disintegrated. So, I probably going to need to purchase whole strips, if I can find some for a reasonable price. [/SIZE][/FONT]Re: Samsung UN46EH5000, No Backlight

Re: Samsung UN46EH5000, No Backlight
Here's a photo of the LED with lens removed.
I can't see how to get it off, without destroying the strip. And how to get a new one back on?...Leave a comment:

Re: Samsung UN46EH5000, No Backlight
I bought a new one yesterday on sale, w/ a 5yr fix or replace plan. Now the failed one, with be my project TV. And if I can fix it, will become the kids gaming/movie set.
I'll try removing one of the LEDs, and let you know....Leave a comment:

Re: Samsung UN46EH5000, No Backlight
I was able to figure out where to test the LEDs individually, using a home-made 3VDC test cell (2 AAA batteries in series, with straight pins soldered on). The pins slid under the LEDs perfectly.
I found 4 bad LEDs, on 4 separate strips. Problem is, [U]all[/U] the discount stores are out of stock (Shop Jimmy included). Looks like they are not making them anymore. Electronica USA sells strips at $20-$24 a piece (as opposed to SJ at $60 for a set of 8). I was going to buy all new strips to lower the risk of having a reoccurrance,...Leave a comment:

Re: Samsung UN46EH5000, No Backlight
Basically, a jack of all trades, master of none. I've done a little bit of everything, EXCEPT electronics, although I have done some automotive wiring. So, this is my first endeavor in this area. I have a multi-meter, a couple of soldering irons, and a bunch of automotive wiring fittings....Leave a comment:

Re: Samsung UN46EH5000, No Backlight
So, how do I test the LEDs? I tried putting two AAA in series, and testing at the two holes on either side of each LED, but that didn't work. I assume those small holes are there for just that purpose, correct?...Leave a comment:

Re: Samsung UN46EH5000, No Backlight
So, if the diagnosis is a problem with the LED strips, can anyone comment on whether or not it is worth the time and money to replace them? Is this an enduring repair, or really only temporary in most cases? I saw at least one post where the problem came back after being fixed and working for a while. Saw another post where the poster felt that once the LED strips go bad, the TV is ready for the recycle bin.Leave a comment:
