Hi. How are you? You had discussed a issue with a Toshiba model 50L1350U in a post a few yrs ago. I've one with the same issue and its the exact same model too. Was there a trick to taking it apart?Did you ever fix that set? -
Gigabyte GV-N950OC-2GD GeForce 2GB Graphics Card
Hi. How is everybody?
I've a Gigabyte GV-N950OC-2GD GeForce 2GB Graphics Card that has no video out.The fan works but the rest of the board is dead. I checked and there are parts fried that directly connect to the female power connector socket terminals. Anybody have a board like this that they can look at at and give me the part numbers and part local info for it?Maybe someone has a diagram for the board. Thank you all in advance and if needed I can supply pics. -
Sharp TV LC-60L3650U Doesn't come on
Hi. How is everybody doing?
I've a Sharp 60 inch TV model LC-60LE650U that doesn't power on.The Power led flashes 3 times then once in sequence. I read that the POWER Led flashing in the 3-1 sequence is a error code indicating that the main board isn't communicating with the power supply.There's threads indicating that it's a main board = tuner board fault and not a PSU = power supply failer.Can anybody confirm that info? Has anybody fixed this issue before. Would anybody know exactly what part/parts failers cause the 3-1 led error code? Doe's anybody have any diagrams for this set? Feel... -
Re: Samsung pn64e550 power cycling
Thats good to hear , let us know what happens in the long run thank you -
Re: Samsung pn64e550 power cycling
Hi there is a video chip that can cause that issueand sometimes a cap on the psu causes such issues. I'd forsure resolder all the connections that you can and then see how the set works. You may wish to try some freeze it later.Leave a comment:

Re: Westinghouse EW46T4LZ
That board does look like someone has worked on it and part of that circuit looks like from your pic that it could be damaged or burnt.Leave a comment:

Re: LG 50LA6970 Audio Issues
Try a few different HDMI cables, also try connecting different sources to the same device, then try different HDMI ports. I've seen sets that are extra sensitive to what type of source you have it connected to and what quality and length etc of HDMI cable used.Try resetting the the different devices or turning them off and on after changing HDMI cable.
If both of those sets worked before trying to switch them it sure sounds like either a bad HDMI cable or bad HDMI port , or they needed to be paired probably to each source or they don't like the...Leave a comment:

Re: SATA /PATA external supply ?
Check those 1N4007 there are 4 of those they usually go along with the fuse and mosfet but from your pic the resistor by the cap looks burned too.Leave a comment:

Re: Emerson LC401EM3F ps replaced, tv comes on, inputs dont work????
I'd try cleaning the ribbon sockets and ribbon connectors with 70 or 90% rubbing alcohol and a tooth brush. Make sure ribbons are fully seated probably.Leave a comment:

Re: Panasonic SC Board - BAD 30F131 IGBTs
I've purchased mosfets and other parts from UT without issues, plus I know some friends that purchase parts from them too.Any supplier could get a bad batch or they might end up even getting faulty parts from a seller that they never dealt with before.Leave a comment:

Re: Question: Samsung PN64E550D1FXZC
Sounds like you sent them an email they also have a phone number that you can call to get a quicker response. I've called them before but that was months ago so I don't recall their ph no off hand.I checked their web site and I'am not sure what country you're in but heres the phone numbers 877-881-6492 , 952-881-6492.Last edited by Electronic Handyman; 07-03-2016, 09:06 AM.Leave a comment:

Re: Question: Samsung PN64E550D1FXZC
I can bet that any kits that are sold by shopjimmy are parts theyve used themselves.Leave a comment:

Re: Question: Samsung PN64E550D1FXZC
It could be a case of the original part is higher rated then truly required for that board, Shopjimmy maybe supplying a part that is within the boards specs and it might even be a better quality part then the original. Manufactures many times when assembling different boards use whatever is on hand within the required specs so you could see different parts in boards.Leave a comment:

Re: Kdl-46s4100
Those KDL Sony models are famous for T-con board faults and from your ribbon test it sure seems like yours has a bad t-con board too.Leave a comment:

Re: Samsung Smart TV UN32H5500
If you don't wish to spend more money on a main board you may want to see if any of the electronic recycling centres in your area have a set like yours maybe with a busted screen etc they usually sell them for quite cheap.Otherwise I'd suggest that you go over the main board and see if it has any bad soldering connections.Unplug and re-plug in any main board connectors.Do the same thing with any ribbon connections, you may want to clean the ribbon connections and ribbon socket connections. You'd be surprised in how many sets I've repaired that had...Last edited by Electronic Handyman; 06-16-2016, 03:47 AM.Leave a comment:

Re: Sony KDL-32NL140: Powers On w/ Backlights, Black Screen - Bad TCON?
I'd check the power supply board's voltages and the main board too.By the way 11.97v is close enough and with the voltage tolerance range.Last edited by Electronic Handyman; 05-23-2016, 07:25 PM.Leave a comment:

Re: Emerson LF391EM4F picture blinking on and off
I've looked at your pics and I maybe wrong but from the blow up pic view it looks like there's some bad capacitors on the power supply board.On the board you see the numbers BA3ATHF0102 2 and above that board parts numbers to the left you see 2 capacitors side by side.Those two capacitors sure look bad and I'd not doubt that those and maybe some other capacitors are faulty on that board too.
I'd check all the plug in connections, solder junctions and the whole boards soldering connections. Re-solder all the board's...Leave a comment:

Re: LG 50PS11 plasma -top half of screen darker
Many times in such cases when a set is acting up then is moved etc and acts differently I find bad soldering connections or a loose connector or even bad connections on the plug in soldered connectors.I'd re-solder all the hot spots like parts connected to or close by the heat sinks, any coils on the y-sustain board especially the two red coils and the big capacitors connections.Check those caps carefully bec they are known to fail too.Leave a comment:
