Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

Possible failure in the horizontal section of the horizontal driver or the failure of the line output transformer.

Blue horizontal and vertical lines


We have many problems with loose or poorly seated cables and connectors on these units. Pull the back and reseat all the internal cables, especially the LVDS cable to the LCD control bd. If this does not correct the problem the main cause is a bad LCD control bd. or possible a defective main bd.
