    I will look up the data sheet on both chips, I suppose they are compatible, I think they just sent this out with a garbage dump on it.

      Ok, contacted the seller, they said you have to match every letter and number of the part number, my part # is 02-SLS39A-C005000 001, the one I bought is 02-SLS39A-C003014. Looks like the first eight numbers match, does that sound like an explanation for it being badly damaged or not able to work for my board, if so then it was my fault for not knowing that I needed to match every number in that string. Thanks Lotus for the assist.

        This dump has a severely damaged firmware core and this firmware will not work on any TV or you did not read it correctly from the chip (bad contact...), I cleaned your original dump for you, write it down correctly and check it.

          Ok, thanks, that's what I thought you meant when you said it was severely damaged, which is it is not fit for anything, so is it true that I should have matched all the numbers or was the first eight numbers enough? I only read the new chip once, I'll read it again. Since I don't have a 25 adapter, I put the new chip in the clip to read it.

            It’s not the numbers that are needed here, but the TV model, motherboard number, panel number, and TV tuner that match.

              Starting to wonder if the programmmer I bought is defective, it will not read either chip now, it doesn't say not connected to chip but all I get is f's on all lines after reading, going to try it on a 24 and see if I get a reading.

                I know these cheap programmers usually mean they are harder to deal with, what inexpensive step up from ch341 do you recommend?

                  25 is a spi flash, and 24 is an eeprom, they are completely different, and they have different pinouts, the main thing here is that 1 pin of the chip corresponds to 1 pin on the programmer.

                      Well the goshdampos programmer will not read anything, it read those two chips, that was all it did. Tried it on 4 others and those two again, nothing but f all across. Sending the programmer and the chip back and starting over OR giving up.

                        Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                        by Tynan Dill
                        I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                        Upon bringing it home and plugging it up, it showed a standby light.

                        I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                        The screen seems to blackout and stay black, but with a flashlight I can see the display.

                        With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                        MSI GT70 2PE Voltage dropping on the main power rail
                        by HERETIK10
                        Hi everyone,
                        I have a strange problem (for me) on an MSI GT70 2PE laptop.
                        When it's under heavy load, power goes steadily to the battery (for 2 or 3 seconds) then return to the charger. If I remove the battery it turns off.
                        The higher the load, the lower the voltage on the main rail. We go from 19.5V, PC connected to the charger but turned off (normal consumption of 0.06A)
                        On, when it draws 2A the voltage is 19.2V, then eventually collapses to 18.5V (and turns off) around 5A.
                        I removed the first 2 mosfets (PQ13 & 14) from the main rail, without noticeable change....

                        Hi and thanks in advance for any input you might provide!
                        I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.

                        Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this...

                        I wondering if there are some usual faults regarding the PS_ON signal from main board to PSU board?
                        Where do i start looking?

                        I have standby light and the PSU is working if i connect 3.3V to the PS_ON pin on the psu board....

                        Panasonic TH-L42D25A checking the PSU output voltage
                        by electron_jj
                        Hi Everyone, I am new to this forum. I have a Panasonic LED TV which doesnt turn on and is blinking 4 times repeatedly when I turn on the switch. The TV does not respond to the remote control so I had to turn on using the physical switch on the side of the TV. When I turn on the switch the 4 x blinking starts and repeat itself until I turn off the TV. There is a black screen. I turned off the light in the room to check the panel and I think there is no backlight as far as I can tell.

                        I have been inspecting and testing the capacitors and diodes in the power supply board to try to...
