I have the same issue with my RU42PZ61, and I think it's the power supply board, but I'll take it to my repair man. He diagnoses it for $25.00, and tells me what part I need.

Hello, My LG RZ-42PX11 is broken. Only yellow and light red is shown and white vertical lines. What is broken?

The T-CON board is bad. However, these rarely fail on their own. I would suspect an over voltage from the power supply or damage from dropping. However the vertical lines are from the broken T-CON board that is on the top edge of the panel

Hi, i have an LG plasma, model number RT-42PX11.

You need to pull the power supply out and replace the damaged caps on the board. Look for swollen, pushed up tops and leakage around the base of the caps.

You need soldering and basic electronics skills. You also need to pull apart that big tv and pull the power supply board!

You can look on Ebay for pullout boards from people who have broken their screens. It can get you a working board for cheap sometimes!

Good luck and be careful!
