    Westinghouse ld-4655vx upside down display

    No backlights and image upside down.

    I have a LD-4655 from Westinghouse. On arrival it didn't have an input board. I purchased one by model number. It would not power on. I found the lvds cable on the left side of the screen to be damaged. After repairing the cable The tv will power on without backlights and the image is upside down. Unhooking one cable at a time Doesn't allow the backlights to power on as described in other threads.

    Does the upside down image and no backlight indicate a bad input board?

    upside down image is because the panel isn't matched to the settings in the service menu on the main board. I don't know how to get into the service menu on this particular model.

    As for the backlights not working: You have to first figure out if the main board is sending BLon to the PSU. This way we can see if the fault is on the main board or somewhere else.

      Samsung UE48H6410 replaced Mainboard but backlights doesnt go on
      by max789
      Hello, I have a problem with my Samsung UE48H6410SSXZG with the main board BN41-02156A and the power board BN44-00709A. Everything seemed like this, the TV could no longer be switched on, the standby LED always flashed 5x2 times. Backlight was off and no sound from TV. Also made the flashlight test and there was no picture.

      I made the following tests:
      1. Disconnected the main board from Power Board = backlight works.
      2. Connected the main board and disconnected the T-Con = backlights does not work.

      So I ordered a main board from Ebay also BN41-02156A but from...

      VIZIO M557-G0: Backlights or ???
      by bpcannan
      'Morning,
      I get sound and picture when powering on the TV and its stays that EXCEPT that the left half of the screen will dim every few seconds then return to normal while the right side of the screen performs as designed.

      Did the soft and hard reset options pulling the plug, using the reet option in the vizio menu to no avail.

      I checked the mainboard - found some popped capacitors so replaced it - but that did not change the situation.

      I checked the t-con board. It is getting good power. Then I removed one ribbon cable to see if I could isolate...

      Samsung UE49MU6400 acts dead until disconnecting backlights, then works.
      by jesterace
      Hi everyone I have this TV which was dead one day when I tried to turn it on. I've had the cover off and there was just a pulsating/electrical clicking/ticking noise from the PSU. I disconnected the mainboard as sometimes this works to just fire it up with backlights on? That didn't help. Same noise. Then I disconnected the backlight cable from the PSU and the TV came alive. It appeared to respond to the remote and i'm pretty sure it's fully operational when there is no backlight connected.

      However, I am in a dilemma.

      I tested the backlight outputs with the lights disconnected...

      by jimbofz
      Hi this vestel 65in tv had classic no backlights ,so nothing new there!
      tested with b/l tester and the b/l seemed to be fine
      so investigated psu 17ips72 (on this 65inch there are 3 fets and control iv type DB83630P)
      did a thorough check on b/l circuit all ok .
      When i tried again with b/l tester all ok .but then when i reinstalled psu all worked fine ,
      could there be a component on psu that is causing the protection mode to stop b/l
      .maybee causing it to be too sensitive?
      it seems to me if the b/l have been on with my tester ,within a couple of minutes...
