    Insigna NS-lcd37 no sound

    Insignia NS-LCD37, Perfect picture but no sound. Tried all outputs, and the optical out. Nothing. Bad main board?

    I would check all connections first. Post pics of all boards, could be a Signal Output board, audio board (which is in the main board on that one I believe) or a bad connection to the output board. Post pics and model numbers of all boards inside.

      I checked all connections and power supply voltages. Camera is down so no pictures. the main board has 2 numbers 782.26HA37-690E printed on the board, and 37HA37-69 on the barcode sticker. I think I have a bad main board, but there are two different panels on this TV I have the one that is not the LG-Philips. Chumwa or something like that. Anyone have a service manual that can tell me what board to order?

        Issue: No Power, Then Rebooting After Main Board Change

        Short answer: replace main board and power board
        Technical answer: replace main board and Q306 & Q307 on power board.

        Long answer:

        TV wouldn't turn on. Power switch was fine which means the main board isn't processing the power on signal. Replaced main board. TV turns on now but randomly reboots. Bad main board? EEPROM? Tried to pull main board and got a shock touching the corner of the board. That's weird. C334 (450V 10uf) capacitor is still holding a high charge....

        HP Pavilion 15-eh Board DAG7HAMB8F0 - CPU throttling to 0.4GHz (PROCHOT_EXT) and black screen
        by m1ch43lzm
        Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
        Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

        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...

        Driving a Sharp TCON/panel with a universal main board
        by advant
        This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.

        I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match...

        Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
        by Asraf Atb
        Hi everyone,

        Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

        Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

        I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....
