How to determine that the matrix on the samsung le32b350f1wxua has become unusable?

Question

Samsung

Hello. Available TV samsung le32b350f1wxua. Since 2009, he has served faithfully. Today, when turned on, the screen showed a muddy picture. It feels like a cellophane bag is on the screen. Only from below (5 cm) horizontally normal color. In all modes - TV, DVD, even in the menu everything was muddy. Then in general colors were strongly distorted. It got purple. After a few turns on and off, the blurring is gone, but there is a red stripe across the entire screen. Does the matrix get kirdyk? Previously, I wanted to update the firmware of the device, but apparently this is only possible in the SC, because there are no connectors for this.
How can you do a full hard reset on this model?

Answer 1

This is one of those cases when it is better to contact the service (specialist, engineer) directly.
At least for diagnosis.
