SOURCE: Vizio 42" LCD HDTV audio issues

First of all go into the audio menu settings and turn off the "surround" feature off and that should fix the voices/music differences. Does the craking sound appear while watching any sorce such as cable box,sat rcvr or DVD player? If not isolate it to that input and maybe that device is giving the problem.

SOURCE: We had a power outage and the next day all I could get on my TV was the blinking power light. Can you hellp me? I have a Samsung 42" LCD Flat Panel HDTV Model No. LN T4042N edit

Hi, the power surge has destroyed the power supply board that is located inside your lcd cabinet. this board works in conjunction with an inverter board that regulates the raw ac current that is used for many different functions in your set. Normally, this type of damage will be isolated within the power supply but, it could have spread to the main control board as well, depending on how well the surge protector preformed during the surge.

The good news is that, this is a repairable situation. you can replace the power supply circuit board and inverter board as well. these replacements will fix this issue.

please rate and god bless:)

SOURCE: How do I change a power board on a 42 inch Olevia lcd hdtv. Model: 242-t11

take the back off. find the board that ac cord is connected to.there are six screws,four plugs and a ground wire. carefully remove the plugs without breaking any of the wires.(the first time a plug is removed it can be quite hard to get out.) then remove the six screws and the ground wire connected to the chassis.lift out the board replace it with the new one and reverse the the instructions.

Hello Mendez the problem that your tv set is having is coming from the inverter board this board provides the high voltage for your backlight without the backlight no picture, what i want you to do is go online sometimes this happens go online look for the service manual for your tv set once you find it get it look for the inverter boards location and check the fuse that is on that board sometimes they blow and it will give you this problem if that is your problem you save money and the hassel of taking it anywhere to get it fixed,if it is not the fuse then the inverter board needs to be changed out and that will fix your problem thank you hope this helps.

My 42" flat screen phillips


I'd post TV model number first - it's on the back of the TV -and I'd also post a picture if I could.

The lines on the screen do not usually go with the "channel not available" problem and the likelyhood of you having both at the same time is , well, small.
