Re: Samsung UN39FH5000FXZA (Ver. PF03) Component Identification

I very much appreciate the information. It seems most the TVs I've ran across have had bad LEDs. I figured the reason ShopJimmy wasn't selling the same ones, but a compatible one, was because the...

Re: Help finding resistor for Craftsman 82357 R41

I bet I know what I did!!!! Months ago, I was working on a TV and accidently grounded out the leads while measuring voltage across a very large capacitor on a teli! It actually disfigured my...

Re: Help finding resistor for Craftsman 82357 R41

It was bought for me by my parents when I was very young. If I remember correctly, it actually came from RadioShack. They had it locked in their display case (well, same model, but the display...

Re: Help finding resistor for Craftsman 82357 R41

I should have listed what was wrong. Taking measurements, such as resistance or checking continuity, sometimes, the meter will lock up. Measuring capacitance, same thing, sometimes, locks right...

Re: Vizio E65X-C2 no 5V_Stdby

I forgot to update the thread. I had originally tried powering it with the two diodes in parallel, before you I read your post here, and had 5V_STDBY. I tried turning it on quick like, but it...

Re: Samsung UN39FH5000FXZA (Ver. PF03) Component Identification

Hrmm. This is something I need to think about. I noticed with most of the TVs, especially the Samsungs, ShopJimmy doesn't have the same LED strips available, but a compatible strip. Do you guys...

Re: Samsung UN40D6000XFZA Ver H302 Possible Bad T-CON or Panel

What's giving me some troubles identifying the fault, the vertical lines are almost symmetrical, as you can see in this video, with a video source hooked up to the TV.

Re: Samsung UN39FH5000FXZA (Ver. PF03) Component Identification

Yeah, I think I am going to try testing individually and replacing just the bad ones. In the past, it didn't matter much, because if any strip was bad, I would replace all of them. That gets a...

Re: Help finding resistor for Craftsman 82357 R41

Maybe a Yageo MFP50SBRD52-20K2? I just cannot seem to find much for this resistor. DigiKey and Mouser didn't seem to have any resistors that matched this value, unless I wanted to purchase a...

Help finding resistor for Craftsman 82357 R41

Hi!

I have a Craftsman 82357 that has been good to me. It's old, but we've been through a lot and I'd rather not replace it if I don't have to. It's been acting up lately so I pulled it apart...

Re: Samsung UN40D6000XFZA Ver H302 Possible Bad T-CON or Panel

I am not 100% sure on the name of the boards that connect to the panel and the T-CON. I have always referred to these boards as driver boards. I've taken the cables that come from these boards,...

Re: Samsung UN39FH5000FXZA (Ver. PF03) Component Identification

Don't the old LEDs shine at a different brightness than the new ones? Or isn't it normally noticable?

For what it's worth, I replaced the MOSFET, but some of the LEDs are bad. Owner doesn't...

Re: Grundig 49 VLE 6620 BP Led *Backlight blinking

I had a television recently, a Samsung, that blinked on and off like that and it turned out to be the LEDs. One strip was completely dead or shorted, I just replaced them after testing. I would...

Samsung UN40D6000XFZA Ver H302 Possible Bad T-CON or Panel

Hello!

I'm working on a Samsung UN40D6000XFZA ver H302 LED backlight LCD and I am having some issues determining if the T-CON is bad or if the panel itself is bad.

If I unplug both ribbon...

Re: Samsung UN39FH5000FXZA (Ver. PF03) Component Identification

Do you replace all of the LEDs? I've been replacing the entire strips, but sometimes, it's too costly. I thought about attempting to replace the individual LEDs. I was thinking I would have to...

Re: Samsung UN39FH5000FXZA (Ver. PF03) Component Identification

Yeah, but let's say one or two of the 6 are out. At 18V, with two out, would none of the six light up, or would the four working ones light up with a vF of 4.5VDC, possibly frying the LEDs?

Re: Samsung UN39FH5000FXZA (Ver. PF03) Component Identification

How hard is it to replace the individual LEDs? I do not know how to test in groups of 6, but I will take a closer look at the strips. I have a good set of 3 strips from a bad Samsung TV that had...

Re: Samsung UN39FH5000FXZA (Ver. PF03) Component Identification

So real quick like. The LED strips are bad. I have a Rigol DP832 3-channel programmable power supply that can provide up to 30V/3A per channel, except the one, which provides up to 5V/3A.

Re: Samsung UN39FH5000FXZA (Ver. PF03) Component Identification

I can find a MOSFET on DigiKey with a Continuious Drain Current of 10A or 40A.

One appears to be the same package, TO-252-3 (TK10S04K3L(T6L1NQ-ND)) but that has the Continuous Drain Current of...

Re: Samsung UN39FH5000FXZA (Ver. PF03) Component Identification

Now I need to find a compatible one that DigiKey or Mouser (preferable at DigiKey) that I can order. Anyone...
