SOURCE: ViewSonic N2750w 27 in Volume turns down by itself

Could be a problem with the down volume button on the tv. the board it's on ir its harness. Check them all. Make sure the volume buttons plastic actuator moves freely and is not stuck.

If these parts are all good, you have a problem on the main board. You may have to trace the control lines as far as you can and check any capacitors along the way. If you have an oscilliscope you can test the lines to see if the up volume is working correctly. If there is noise on it, you might find a bad capacitor if you can trace it back far enough. Schematic helps here.

Of course, make sure nothing is shining on the sensor window on the TV. You might want to scope that line as well (IR sensor line).

If none of that helps, get hold of Viewsonic and find your closest service provider. You can order a main board from them.

Of course, you could try just using the audio out jacks to an amplifier or a surround sound amplifer. Then you would use the remotecontrol for the surround sound system to control your volume.
Bet you were going to buy one anyway right?

My tv turn off by itself all time, sometimes Its just turning on when it turn off,sometimes happens after 10 minutes

Hmmmmm.......My ratings are slipping so this will require a serious answer! The solution I will give you will be of most accuracy. Your power supply startup resistors are are bad. These are located on the inverter board. Replace the inverter board or if you are up to it replace R603,604, and 605 with 390K quarter watt resistors. If the values are different or the same as mentioned, use the values I just told you! If they look fine or test fine...replace them with the value just mentioned!!!!!! Anyway!!!!!! Take this info to a TV tech and show him your answer. Thanks for asking me!

The tv isnt turning on at all what is the problem

Targa 32" LCT TV, No picture/ sound only can hear clicking sound from Kisan KP-301R Power supply board. Have checked output voltages and they are a little out i.e. 16v instead of 17.5v and 10.5v instead of 12v.

Has SAMWHA capacitors but cannot see any bulging or leakage anywhere like other users have suffered so dont know if changing all the caps will solve the issue.

Before it finally went dead LCD TV would switch itself off after some time and just a few days before it dies it started the clicking sound but would then start up okay.

Describe your sylvania lc225ssx green screen Problem Screen goes green occasionally. Switching to an HD channel then back usually corrects for a while. Sometimes power-cycle also temp fix.

Whenever I hear "green screen" it is a loose or faulty HD cable(s).

Check your HD connections to make sure they are inserted fully and if there is no change, try an alternate cable.

Sylvania lc225ssx pc imput from inspiron e1405

You have to set the resolution of your laptop to that of the TV can support. Trun off the laptop and the TV, then hook up the TV to the VGA prot of the laptop, then tun the TV on first then the laptop, hopefully the laptop will recognize the TV and allow you to set up the correct resolution on the laptop.
