Check the soldering on the picture tube neck PCB. If possible resolder all the point in the pcb. There is some problem wit the filament voltage. It can be because of drysoldreing.

LCD Thomson 32LB040S5It the sound is always in high volume


I assume you have already tried using the buttons on the side of the TV to adjust it? I would just do a factory reset on it. Enter the TV main menu. Select factory reset to return the TV Menu settings to the factory default values. If this does not fix it unplug to TV for 45min to do a complete hard reset.

I can't program my tv chanel , some of the channerll are missed tv LG flat panel


A simple suggestion that may work--tried to direct enter a channel like 21 enter to see if it goes there? If it does you should be able to go into menu and ADD it to the up/down memory of channels, takes time but if works better than nothing. (can also remove channels in same way---shopping and golf channels are first ones I always delete.

I have Onida TV Model 21 inch , I accidentally enable the features of volume lock, hotel mode and channel lock and I cannot reset the same. Due to this, I cannot increase volume of telivision


MIGHT WORK IF YOU:
Turn off tv with remote, that is standby, then turn off tv with switch or unplug from wall. Wait a few minutes until led lights go off on tv. plug tv back in. try pushing vt on remote and power button on tv at same time.
If this doesn't work try contacting a local retailer, they always have a list of codes for their salesmen.

Hissing sound comes from leak EHT transformer but front LED working means your power supply is ok so you need to check horizontal out out Transister and series resitor feeding to voltage from B+ to that transistor if it's gone pls replace the EHT transformer as well
in srilanka EHT is around $5 and transistor is $1

High Pitch Noise on 42" PLasma Gateway TV


how old is your plasma TV? try check the switch / volume of the sound settings.. Sometimes, when you always increase the volume, it will tend to alter the limit of sound and causing the sound to provide sound undesiredness. I suggest to check it with a liscensed technician.
