Television repair at TTZ-1: a dark screen with sound, bands on the panel or a dead remote — the technician checks backlight and the PSU and names the estimate before repair.
At TTZ-1 we replace LED strips when there is sound but the picture stays black.
Panels are serviced in first-quarter TTZ living rooms by the plant courtyards.

How to arrange a visit
- We cover TTZ-1 housing blocks — the first Yashnabad quarter by the tractor plant.
- Say if there is sound without picture, bands across the panel, or the remote is dead — screen size can be approximate; in first-quarter living rooms the symptom matters more.
- Unplug HDMI and the aerial so the rear cover can come off without tugging cables.
How the visit works
Power supply
If the TV will not start, we measure the standby rail and check the power-button board ribbon.
T-Con and ribbons
When bands or blotches appear, we inspect LVDS seating and panel timing voltages before agreeing on repair.

Topic 1 / 3
TV backlight replacement
If the screen goes dark, you see only shadows, or one half lights up and the other doesn't — the backlight is often the cause. The technician checks LED strips, the backlight driver, and the power supply.
Replacement involves partial disassembly of the case and panel. We explain the scope and agree on the price before repair starts.
