Because your unit is in Child lock Mode....

I have not worked on your particular model. But, I have serviced many TV sets over the years. My answer will ge generic.

Check all the capacitors in the horizontal output stage and power supply areas for high ESR. All the caps that are out of spec must be changed.

The high voltage multiplier & flyback can also cause the fault you are having.

You have to consider that the DC voltages are not the only important spec that has to be met. There are also many power drive signals that work with reactive devices. If there is any defect in the critical areas there will be failures.

I have problem model TCL-14175 I replace ic 8 pins 44608P40 but still unstable power supply


You've replaced the main system control memory IC, I assumes. If so, an adjustment called, memory initialization, should be done after replacement, or, the newly prepacked IC do not work. If you wish to get more details about this, check this link. http://electronicshelponline.blogspot.com/

I have TCL TV set. When I on the power of TV set, tv shows message ASM after 3 second in Red and auto scanning running. I already plugged the cable so many times, but same problem continue. Please help.


Hello
The mamory IC inside the circuit of your tCL tv is faulty. Memory IC is one which transfers data to main system IC when we switch the set ON each time. Now it transfers the data to the system IC ofcourse, but not memorize the [LPM]; last position memory. This IC can be located very nearto the main system IC; will have 8 solder terminals. It can be easly unsodered out and resodered in. Its number is most important. Keep a keen look on its number and buy an exact replacemnt. It will be very cheap to buy, and can be had from most of the electronic spare part shops at your town. OK.

Tv wont turn on


Hello Charliebigwh, hi technically your monitor's power supply has a problem, this is either your switching regulator does not work or there is a short in that section, If you want to do it your self, need to replace all large value, and or high voltage capacitors(especially the capacitors with its top is bubbly), need also to replace the switching IC, and power transistor.

Have it checked by a technician if you cannot do the work.
