Tv tcl-14175 no sound on channels but ok on audio video mode

The first problem was always standby mode, and I replaced the flash memory IC 24C08WP with 24C08 from the same ST manufacturer brand and got my tv to display channels but theres no sound on all channels. but theres a sound when audio video mode on my DVD player. i checked on the audio output of the large IC and theres a humming sound when I touch the test probe pin while taking voltage test. I replaced the crystal 4.5MHz but still cant solve my TV problem. I checked the menu settings on display for the hardware through my universal remote control but I dont know how to remote adjust coz I dont know the proper settings with the 22 OSD selections from video to audio. I only got my exact adustments for the vertical size and height. but cant get thru the audio settings. Will anybody can pease help me?

The first problem was always standby mode.... get back the original eprom IC 24CO8WP in to the PCB, then find the original remote control of you TCL Tv tcl-14175 then you power On In the Remote control while your TV is in Standby mode! then you see your tv is going ON... Because your unit is in Child lock Mode....

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.

Tv channel lock up

It sounds that the main system control memory IC is faulty. Replace it and check. It is a very small IC, having 8 solder terminals, and can be located very near to main system control IC. Will look somewhat like this.

Check and replace its main system control memory IC. If this IC is faulty, auto tuning will not work, or, the TV will store any received channels. If the TV do not tune into channels too, the AGC voltage to its tuner, and tuner itself should be checked.

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.

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.
