Many repairmen had to deal with the typical malfunction of some models of LG TVs when he loses the channel setting.
The defect may appear periodically at first, but in the end there comes a time when tuning to digital and analogue channels becomes impossible.
This is often caused by a malfunction of the TDTJ-S001D tuner (p / n EBL60721201), which can be installed on the LG TV models listed below:
19LD350, 19LE3300, 19LV2300, 22LD320H, 22LD350, 22LE3300, 22LE5500, 22LE5510, 22LH200H, 22LH250C, 22LK330, 22LV2500, 22LV5500, 26LD325, 26L, 2500L, 26L, 2500L 2600, 26L, 2500L 32LD320, 32LD325, 32LD335, 32LD340, 32LD345, 32LD350, 32LD351, 32LD420, 32LD425, 32LD450, 32LD465, 32LD550, 32LD551, 32LD565, 32L3300, 32LE4500, 32L32L, 32L, 32L, 32L, 32L, 32L 3250, 32L 3250, 32L, 32L, 32L, 32L, 32L, 32L, 32L, 32L, 32L 32LV3550, 32LV355C, 32LV355H, 32LV4500, 32LW4500, 37LD420, 37LD450, 37LD455, 37LD465, 37LE4500, 37LE5300, 37LE5310, 37LH200H, 37LK430, 37LK450, 37LV3550, 37LV355H, 37LV4500, 42LD420, 42LD425, 42LD450, 42LD455, 42LD465, 42LD550, 42LD551, 42LD555, 42LD565, 42LE4500, 42LE5300, 42LE5310, 42LH200H, 42LH250C, 42LK430, 42LK450, 42LK530, 42LV3400, 42LV3550, 42LV355C, 42LV355H, 42LV369C, 42LV4500, 42LW4500, 46LD550, 46LD551, 46LD565, 47LD420, 47LD450, 47LD455, 47LD465, 47LE5300, 47LE5310, 47LK530, 47LK950, 47LV3550, 47LV355C, 47L V355H, 47LV4500, 47LW4500, 52LD550, 52LD551, 52LD565.
Also, the TDTJ-S001D tuner can be used in plasma TVs, in the models:
42PT350, 42PT351, 42PT353, 42PW450, 42PW451, 50PT350, 50PT351, 50PT353, 50PV350, 50PW450, 50PW451, 50PZ250, 50PZ550.
TDTJ-S001D is designed to receive channels of meter and decimeter range within the range of 45.25 - 863.25 MHz, as well as digital channels of terrestrial and cable television standards DVB-T and DVB-C. Color Standards: PAL / SECAM, Input Impedance: 75 Ohm.
The appearance of the tuner is already familiar to many and is presented in the figure below.
Tuner TDTJ-S001D
In most cases, replacing this tuner with a new one is completely optional and its performance is easily restored in an equipped workshop.
The tuner should be removed using a soldering station. In order to prevent damage to the tuner or the motherboard, we do not recommend soldering it using only a soldering iron and a spring "suction".
The defect is usually caused by broken contact connections in solders, as in many tuners of the good old CRT TVs LG, Samsung, Sony and Toshiba, which experienced masters remember well and have long been accustomed to their malfunctions and glitches.
The recovery technology is simple.
The conclusions of the metal partitions and the side connections to the body can be soldered using a soldering iron. Soldering joints of small planar elements in most cases is not necessary. The main thing is to replace the solder under the square microcircuit, which is without legs (on the underside of the tuner board).
Next, we wash off the flux residues, solder the tuner in place and make sure that all channels are tuned and working.
For experienced repairmen - no problem.
In no case do not recommend this to users of televisions that do not have the necessary equipment and sufficient repair experience.
Attempts to independently remove the tuner often end in replacing the motherboard, the cost of which can be unexpectedly expensive for the owner of the TV.
A file is distributed on the Internet in which an experienced telemaster recommends pouring the tuner with epoxy.
In our opinion, this procedure is completely redundant and can only complicate the situation during subsequent tuner repairs.
