        How would one go about reprogramming the Flash IC, where could you locate the firmware. Please could you tell me how you came to that conclusion. I'm still learning and have just returned to TV servicing after many many years and firmware in TV's is all new to me .
        Thanks in anticipation.
        First you need an eeprom programmer with software. Then you need to buy a new eeprom (digikey or something. Then you need a .bin file for your TV that you flash on the eeprom. Then swap the old eeprom with the new eeprom and you are back in business. It's a pain in the rear end to do and not worth it for a single TV, unless you see as at "educational".
        Things have changed from the old days, that's for sure. Youtube something like tv eeprom repair...

          Hello CapLeaker,
          I could purchase a new EEprom from Ebay, they are available. I think it's an SPI device so I can probably get someone I know to program it or do it myself if I was really desperate. The.BIN file, now that's something I cannot see a way past and have no idea where to find a copy of it for this TV.

          Things have changed a lot since the old days of TV servicing an it is currently a steep learning curve.

          Many thanks for your kind assistance.

            maybe worth sending these a email too see if they do a pre programmed chip

                  Update.
                  Replacement power supply arrived today and I am happy to say set is up and running.
                  Thanks to all who gave an input to resolving the problem.

                    That was a slightly odd fault glad a power supply solved it as it could of possibly off been the main board or eeprom glad you got it right the first time.

                          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.

                          Assuming...

                          Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
                          by sam_sam_sam
                          I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

                          One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

                          Modification to a ZD-987 desoldering/soldering station using a external switching power supply
                          by sam_sam_sam
                          I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

                          I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...

                          Hi, Can we use SMPS Bench Power Supply for Laptop troubleshooting?
                          by shamsudeen
                          Hi all, I just need to know that, can i use SMPS type power supply to test and short circuit detection on a laptop motherboard?
                          I saw 95% of repair guys are using only Linear bench power supply. linear bench power supply is pricy, thats why i planned to get one SMPS supply.

                          i know that in linear power supply the noise will be very low comparing to SMPS supply....

                          Russound CA4 Power Supply Repair
                          by CMCM
                          Hello Everybody,

                          Trying to repair a power supply from a Russound CA4 Multizone Controller (picture attached)

                          Russound no longer supports it but were kind enough to provide a schematic of the power supply (pdf attached).

                          The outputs marked 12v and 20v are all measuring only 1v.

                          The board is clicking, which I think means it is in something called hiccup mode when the flyback transformers switches because of an internal problem or something else on the board Overloading it.

                          The capacitors physically look clean (no bludgesor leaks) and...
