    RCA RLDED4016a-b

    So I got this TV with not turning on symptom.
    Using my backlight tester I confirmed that LED backlight is fine. Ordered a replacement main board TP.MS3393.PB851. With this replacement board TV turned on but original remote control will not work on a TV and side buttons are mixed up(for example if I press "Source" TV will increase volume).
    So I swapped Eeproms and confirmed that it is a problem on my original main board, meaning with my original main board and an Eeprom from replacement board I got TV to turn on with not working remote and mixed up side buttons and the replacement main board with original Eeprom won't turn TV on.
    So I used my CH341A to read the original Eeprom and it reads and writes back in it no problem. Now I have no idea how to fix that Eeprom dump file.
    What puzzles me is the fact that model numbers of the main boards are the same.
    How do I find a proper Eeprom dump for my models of TV and main board?
    Or can someone please help me fix the Eeprom dump?
    Thanks!

                  Both Eeproms now work on both main boards turning TV on and side buttons having correct functions.
                  Thank you, lotas!
                  Remote still won't work though

                      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...

                      Sony xbr-65x900c main board issues?
                      by jb_Bak
                      Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

                      Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:

                      Original RTU6549-MAIN-V2 RCA Main Board, CV3458H-A, 7.T3458HA1000.0008
                      by tech9pc
                      Hi does anyone have firmware for RTU6549-MAIN-V2 RCA Main Board, CV3458H-A, 7.T3458HA1000.0008. It is not available nowhere on the internet.
                      I got a Version 1 CV3458H-A, 7.T3458HA1000.0003 off ebay for 30.00 and popped it in and board works but about every 20 or 30 minutes tv loses input signal and have to flip HDMI source than back to get picture up again. Probably from not being the same board as original which had lost its HDMI ports signals. I baked the board in oven but have not tried to put back in yet.
                      Is there a way I could dump the original mainboard 7.T3458HA1000.0008 image...

                      Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
                      by cheeky2
                      I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
                      Obviously the same LVDS connector for the screen connection...

                      Samsung UN75RU8000FXZA bad main board?
                      by Lee M.
                      When plugged in it will click and cycle the BL on and off, no pic and does not respond to remote. When I disconnect the cable from the PS board to the main board and then plug it in the BL will come on and stay on. There are only two boards in this set, the LVDS cables from the panel driver boards connect directly to the main board. Since the BL comes on and stays on I'm thinking the PS board is ok and the problem is on the main board. Should I order another main board or do I need to do more testing? thanks, Lee
