Durabrand BH1304D

Summary

13" A/V set made by Haier.

Manuals

Repair Notes

  • One unit had vertical collapse. Vert electrolytics tested fine for ESR. The flyback-derived power source for the vertical IC was very low/missing due to molded inductor L451 having gone open. Replacing fixed the total vertical collapse issue resulting in 29v at pin 2 of LA78040.
  • After repairing the collapse mentioned above, the vertical height was only about 70% of screen height. Without access to the service menu I put a 10 ohm resistor in parallel with R455 and that made it so the raster filled the screen vertically.
  • Finally the vertical position was too high. I put a 220K resistor between pins 1 & 2 of the vertical IC and that brought it back down closer to center.

Notes

Unfortunately the A/V input cannot be switched to without the remote. Other remotes by Haier have been found to work as well. An example of a universal remote that can change the inputs on this model is the URC-2220-R (seen in some pictures below).
