LCD TV Samsung LA32S81B white screen
The TV displays white images only.
Found one bloated capacitor in the power supply board. Replacing the cap did not solve the defect. Could a missing volage from the power supply board cause this problem? Three potential culprits could be the power supply board, main board or the inverter board, or could there be something else? Noticed the corners and edges of the display are slightly redish, so not sure if its worth repairing. Any help would be highly appreciated. |

The sound works fine. Have tried all the inputs, AV1, AV2, HDMI 1, HDMI 2, PC, Component 1 and Component 2 with the same resuts. The picture and color is there in all the inputs but the background is very white. Occationally the dark spots changes to a cartoon-like green color. |

Would like to know if this type of defect could be due to a defective TCON board? Thanks. |
