Re: Source for LG LGE5532 BGA
I understand BGA is ball grid array as a land pattern. Probably a product of my work. If I say to someone, go replace the BGA, and we only have one on a specific board (like and FPGA or something similar), it is implied I guess what is meant.
Yes I did have a fast finger typo. Looking at the LGE 5332....Leave a comment:

Re: Source for LG LGE5532 BGA
It was the product of what I told was a lightning strike, so I'm guessing it is the entire chip. When I say BGA, I assume that means the entire chip, not just a reball. I don't get the BL_ON signal to ever go high so the backlights never fire, although PS_ON does work. Using a flashlight I can see colored snow on the right side, blank on the other. I never can see a menu and there is no sound. Disconnecting TCON ribbons gives me the expected white screens. I liked it a lot better when manufacturers used separate HDMI switches and you could generally...Leave a comment:

Source for LG LGE5532 BGA
Are there any reasonable sources for the LG LGE5532 XD Engine BGA? I know ali express lists them, but that's a crap shoot. I'm working on an LG 65UF6450 that most likely has a bad BGA. I can't find a replacement mainboard EBT64049103 at all either. I have access to suitable equipment to do the work.
Side note: I haven't had to get replacement boards in awhile and it seems like almost everything is sold out these days. -

Panasonic TC-P65S2 SU or SD Boards Bad?
I have a TC-P65S2 that blew an SC board (I had a previous post about some cross references). When I put the repaired SC board in, it worked with the SD and SU boards isolated and SC50 jumped. I reinstalled the SD and SU boards. I did forget to remove the SC50 jumper, but from what I understand about how that jumper works, that should not cause SC board destruction with properly working SC/SD/SU boards. When I turned the TV back on, the SC board blew again. Based on the fact the SC board was working without the SU and SD boards, it at least makes sense that one or both of them is bad.

Re: Panasonic Q661 Replacements (TNPA5175 SC Board)
Well, I did something I shouldn't have because I was trying to work too quickly. I got everything reinstalled, did the resistance isolation test and had SC50 jumpered. Everything looked good there. No blinks, green LED on the SC board, things looking good. I turned it off and reinstalled the Vfg screws and the ribbon connectors. HOWEVER, I did NOT remove the jumper from SC50. TV turned on for a few seconds, and then I saw a big spark. Shut everything down and noticed Q701 had a hole blown through it. SC2 had a short across it like...Leave a comment:

Re: Panasonic Q661 Replacements (TNPA5175 SC Board)
I'll include my working sheet on what I've replaced on this board. No sheet was included with the repair kit, just labeled bags with the components in them. Not everything was blown on this sheet, but I took a combination of other posts on what to replace. First list has parts that are included with the kit (from a popular repair site) and things in the second list are ones I found from outside distributors (Arrow, Mouser). I completely agree Q661 should be included, but it is not. Even trying to find out the ref...Leave a comment:

Panasonic Q661 Replacements (TNPA5175 SC Board)
Are there any readily available Q661 replacements for the panasonic SC boards (TNPA5175 in my case)? I have used a repair kit from shopjimmy, but it does not have that particular IGBT in it. Finding just this part seems difficult. The original part was a Renasas RJP63F3. Renasas stopped making this a long time ago and they do not have any modern TO220FP IGBT's anymore. I don't trust ebay for IC's, so I want to avoid that route. Based on specs, the ST STGF20M65DF2 looks decently close and readily available. Does anyone have any other suggestions or recommendations on finding just that part? This... -
Re: Samsung HPS5053 Relay Clicking
I ended up checking all polarized caps on the board. I did find one bad 47uF 50V cap (it measured 30uF) that was under that big metal shield in my pictures. I do not know if that was causing my issues or not. I did also replace CM871 and CM874 with 470uF 50V caps. These were the ones that looked like transplants to me compared to the shopjimmy pictures. The shopjimmy pictures in those locations look like the green 470uF 50V other places in the board, but I cannot tell exactly because there are 2 different green label caps. This...Leave a comment:

Samsung HPS5053 Relay Clicking
I have an older Samsung HPS5053 with a continual relay click on power up. It does have a unique symptom though. I have gone through the service manual and the troubleshooting chart says replace the main board because I can remove all of the external cables and short pins 4 and 5 of the CN804-2 test connector with the relays no longer clicking. I am not convinced this is quite the reason though.
If I remove all of the external cables to the power supply, I can jump the PS-ON line to ground and the power supply will turn on with all correct voltages. However, judging by the pitch... -
Re: Troubleshooting 1 blink SOS on 12th generation panasonic viera TC-54PS14
I know this is bumping a very old thread, but I just wanted to report that I just had a TC-P50X1 that had the 1 blink problem. I found an A board on Ebay that had the 9 blink problem. I swapped IC9303 from the 9 blink problem board into the 1 blink problem board and now the original 1 blink problem board boots and the TV works great (for a 9 year old TV). Just another data point that IC9303 can certainly fix the 1 blink problem. It might not be the only cause of it, but it can certainly...Leave a comment:

Re: LG 37LC7D-AB Power supply squeal
Long dead post I know, but I had a LG32LF11 with a similar issue. TV would not turn on at all. The 2.2 ohm resistor (R501) was open like the OP. I replaced it and it squealed like the OP's. I found that ZD501 was shorted after finding this post. My TV uses a 1.2 ohm current sense resistor (R503) versus the OP's 0.68 ohm.
For my contribution to this post, I found that my zener diode was a 3.6V zener. I'm not sure if the marking just was not representative on the OP's zener, but the zener on mine is a 3.6V This also makes sense because...Leave a comment:

Re: Sharp LC-60LE633U Panel Board and Tcon problems
So I got back to this TV after some parts came in. I fixed the Tcon where I no longer have the green lines, but the same 1/4 of the panel still does not work. I looked at one of the driver ribbon cables and it looks like there might be shorting damage, but I do not have a good way to check this. It does not seem like manipulating any ribbon cable has any effect one way or another. Is there anything else I can try or is this just a dead panel that is not worth any more effort?

Re: Sharp LC-60LE633U Panel Board and Tcon problems
I think it is a little of both. It was digitally zoomed so there is some weird artifacting, but I think what you are seeing is the aftermath of my probe tips checking for shorts. There were no other track to track shorts, but it probably slightly deformed the leads. I will clean that up before I power it back on. I'm not worried about those as I will get it resolved after I get a cap back on there....Leave a comment:

Re: Sharp LC-60LE633U Panel Board and Tcon problems
I verified on both sides (the blown cap side and the good cap side) that one end was connected to ground (you can see the fatter copper trace side in both pictures). Then with the black lead on ground, I measured the DC voltage on both the broken trace and the side with the cap still in place. Both were 15.5V. Based on what I see, a 0.1uF 25V-50V 0603 cap is possible. Does that value seem appropriate?...Leave a comment:

Re: Sharp LC-60LE633U Panel Board and Tcon problems
Understood on the "lcd to lcd" cable. I was referring to the interconnection cables between the bottom connection boards. I didn't mean to sound defensive if that's how it came across.
If I disconnect that LCD to LCD cable, whichever section I disconnect just goes blank (black, not white). That is true for both sides. I found the issue with where that capacitor broke and will include the picture. When the capacitor blew, it took out one of the traces with it. I checked both sides of that trace...Leave a comment:
