Zenium
The shenzhen television and maintenance centre has a strict regulatory system, quality of service, professional maintenance technicians, advanced detection equipment and good reputation. The shenzhen shoshone television maintenance centre, which has been trusted by a large number of television clients for many years, is based on the concept of serving the people. At the same time, the centre has been joined by a large number of former vendors, post-service technicians and engineers from both within and outside the country, thereby improving the quality and efficiency of maintenance. The maintenance staff have a hierarchy of zheng books issued by the ministry of labour, which have accumulated work experience over the years. Not only is there a wealth of practical experience in on-site design installation and operation, but there is also good professionalism and a high degree of responsibility. The quality of services can be ensured. It's normal, professional, convenient, dedicated! Welcome!
Television repair failure in shenzhen: lcd television repair of lcd failure: screen failure (branding, black screen, red screen, white screen, yellow screen, etc.); screen display failure (screen bright spots, bright spots, bright wires, dark lines, etc.); screen content failure (figure colour bias, vague fonts, different font sizes)
Shenzhen's television repair failure 2: lcd television repairing lcd failure: none on (no image, no raster, no acoustic sound, no power light on); switch-on abnormal (oxial switch on, automatic increase in volume, etc.); sound abnormal (low sound volume, sand mute, distortion, etc.); irregular automatic switch-off (auto switch off shortly after switch-off); no remote control (no remote control functioning, low sensitivity)
Tv repair failure in shenzhen, 3: lcd tv maintenance shows drive failure: images are abnormal (image shaking, image blurring, image distortion, colour distortion, images suddenly disappearing, etc.); screen display failure (screen with a light fence, line, vertical line, etc.); images cannot be reconciled (light cannot be reconciled, contrast cannot be reconciled, size cannot be reconciled)
Shenzhen's television repair failure 4: lcd television maintenance panel failure: abnormal voltage (activated, no light on, automatic off, suddenly dead etc.); abnormal currents (discreet within machine after opening); abnormal images (no image, image deformation, image fixation, colour distortion, sudden loss of image etc.) i'm not sure
Shenzhen tv repair failure 5: lcd tv repair high-voltage plate failure: no backlights (lcd screens are not shown, screens black, automatic black screens); no sound image (sound sound normal, remote control normal but no image, black screen) shenzhen lower tv maintenance centre quality services, high technology, wide market support and! I'm sorry.
Project description is loose: three methods for lcd television maintenance:
The same means of powering the 8tt series of television power lines, with the external or built-in power output voltage controlled by 1501, and the 1501 output voltage, which is then powered from a steady pressure block to each circuit. A back-to-back approach is used to check the power when failure is detected during maintenance。
2- lcd television maintenance on image type failure, which is typically handled by capturing the primary image-processing chip and then checking the outer components of the chip (high failure rate of the chip damage, using this method to improve the speed of trouble resolution)。
3. The failure of the screen is judged after the circuit has been inspected. The failure of the screen is judged by proxy。
(b) power supply for tv screens under lcd:
Because we use a lot of plant screens, the screen requests different power voltage. We have to be careful with the electrical voltage of the screen when we repair the main plate. Otherwise, the screens are burned or not lit。
For example, there are two main boards of 8tt3: the first is an electrical system with two sets of 1501 and coil-based screens and an electrical system of the main circuit, which is composed of screens。
In shenzhen, four ways to unlock the telephones and 10 kinds of failure maintenance:
Television de-locking: the child locking function is as follows:
Unlock with a menu key: press the menu key (or the func key), select the feature display menu (system-set menu), have a child lock in the sub-menu, move the cursor by p+/- to the child lock, and set the child lock to " off " by v+/-
2. Unlocking by screen: no lock on screen after such machine child lock
