Re: ps3 fat overheating problem
Did you use good quality thermal paste, like MX4? Sounds like you used the cheap stuff... which is likely contributing to the issue.
Reflowing isn't going to do you any good in terms of long term fixes.

Re: Need help ID'ing a diode - T2D85
Update: The FSQ510 arrived and was replaced on the SMPS.

Re: Samsung UN50F6300AF No Backlights
Glad to hear that you got it working.
As i recall, the four strings are connected as two channels on the power supply board.
The SMPS silk screen shows the output of CH1 as 219V @ 245mA, and CH2 as 274V @ 245mA.
How are you conneting the annoted of string 1 to the cathode of string 2? By a wire? Or by plugging it in to the respective connector?
The LED strip 1, and LED strip 2 are connected on the power supply board once you have it hooked up with the wiring harness. This makes output...Leave a comment:

Re: SILO branded tv - model SL-4013 - no image, Nonbacklight, doesn't always turn on
I guess my best option for a quick sanity check is to get a known good firmware image and a replacement SPI flash. SILO doesn't appear to provide one.Leave a comment:

Re: SILO branded tv - model SL-4013 - no image, Nonbacklight, doesn't always turn on
Hi all -
Update - I was able to extract the SPI flash contents by wiring up my Aardvark SPI flash programmer to it. I dumped the contents twice and compared the binary contents with a diff tool. Looks the same.
As noted in Post #8, i found a 25Q16CSIG SPI flash from one of my junk boards. The "C" version is electrically equivalent, it just has faster timing so it should be a drop-in compatible.
I programmed the 25Q16CSIG. The programming verified as good...Leave a comment:

Re: SILO branded tv - model SL-4013 - no image, Nonbacklight, doesn't always turn on
I was going through junk boards and found a 25Q16[B]C[/B]SIG. The "C" device datasheet says the programming time is faster than the "B" version that i have on the board.
The other parameters and pinout appear to be the same from a quick glance.
Also, I do have a Total Phase Aardvark that will read SPI devices. I just need to make an adapter board before i attempt to connect to it and read the contents out.

Re: SILO branded tv - model SL-4013 - no image, Nonbacklight, doesn't always turn on
Thanks for the quick suggestions... Sorry for the poor lighting. I've left this TV in the garage - in quarantine if you will. I'll have some additional time to look at this tomorrow.
The SOIC8 is a 25Q16BSIG - a quad SPI flash made by GigaDevice. I've run out of freeze spray and canned air. I'll have to source more cans. Good call.
If we weren't locked down, i'd just remove the SPI flash and take it to work to read out the contents and verify the device...Last edited by ngth82; 04-21-2020, 08:36 PM.Leave a comment:

SILO branded tv - model SL-4013 - no image, Nonbacklight, doesn’t always turn on
Has anyone ever worked on a “Silo” branded tv?
I have one. Model SL-4013. The tv is in great physical shape.
The tv only comes on very now and then. The backlights are good - I dismantled the tv and checked out the strings.
The backlight circuit comes up to ~35V when it’s not working. It goes up to 75V to illuminate the strings when it works.
The big cap stays at 165V in a working and broken state.
The tv doesn’t always turn on either with the remote or the power button. The tv’s red standby LED...Last edited by ngth82; 04-21-2020, 05:42 PM. -
Re: Repair or replace Pal Original Playstation 2 fan
There should be a metal retention / contact type of piece in that white plastic part too for each pin.. I didn't see it in the picture. Are they missing? If so... you can solder on to the board sideLeave a comment:

Re: Samsung UE65H8500 wet inverter board
Thanks for the update!
Too bad -- a 65" TV would be fantastic i think
I have a 55" TV above our fire place as a Chromecast picture frame TV.
50" TVs else where in the house .Leave a comment:

Re: Repair or replace Pal Original Playstation 2 fan
Can you post an up close pic of the white connector and wire ends?
If memory serves, the wires just press fit into the connector.
Worst case, you can just hardwire it by soldering it on to the motherboard connector.Leave a comment:

Re: Samsung Ln55b650t1f Part Identification
Interesting... can you check the four rectifying diodes on that power board? Wait until the big caps discharge first. If you can, either remove the diode from the circuit, or just lift one leg off first.Leave a comment:

Re: Samsung Ln55b650t1f Part Identification
+1 to BudM and the big scary cap comment. It's no joke. Don't die.
Just getting to my e-mail... standby goes down to 1.3V? STBY isn't loaded down when the TV is off (e.g it's within nominal), and shouldn't be when the TV is on.
Edit: also, you are missing a few pin numbers... You have pins 1, 2, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 30... where are the rest?Last edited by ngth82; 04-12-2020, 08:33 PM.Leave a comment:

Re: LG 47LE5400-UC.AUSWLJR - no backlight; no DRV_ON signal
I powered up the TV a little while ago - still works. I'm not under any impression the heatgun will be a permanent fix. Keeping the device cool has its merits.
In any case, the heatsink fins for the processor is very thin. The backcover is almost touching. The cover has perforated holes in this region. Maybe i can bolt on a 80 mm PC chassis fan on to the outside chassis using the existing holes. I can power it from the 24V line and use a variable switching supply board to regulate it down to 12V. Ideally any...Last edited by ngth82; 04-12-2020, 01:40 PM.Leave a comment:

At work, we take our products through temperature cycling and HALT (highly accelerated life testing) in a temperature chamber. The basic premise is exactly what is pointed out in the article and you stress the board at the max operating conditions, and min operating conditions and observe failures (device failure - permanent/temporary, and thermal failure conditions - e.g. Tcase temps exceed max derated values per the device datasheets.
The key here is for a vendor...Leave a comment:

Re: Samsung Ln55b650t1f Part Identification
Yep. Solder the inductor back on.
Take readings with the tv off.
Then take readings with the tv on. This may take several on-off cycles. Since some of them will likely decay since the tv doesn’t turn on all the way.Leave a comment:

Re: LG 47LE5400-UC.AUSWLJR - no backlight; no DRV_ON signal
Agreed. It'll be powered up again in the morning. The unit is in the garage. The low is supposed to be around 39 degrees tonight. There's plenty of opportunity to let nature do the thermal differentials.Leave a comment:

Re: LG 47LE5400-UC.AUSWLJR - no backlight; no DRV_ON signal
I agree -- this series of TVs are notorious for failures.
It still works after 7 hours of running. No guarantees for longevity, but it'll be donated.Leave a comment:
