if av1 has stopped working and all others are still working then it is a problem with the switching IC or interface ic so you will need to reploace the mainboard you can try shopjimmy.com or partsearch.com

Go to your menu button and go to sound set up and turn your sound back on some times if tvs no there are other sounds it will shut off the speakers also if you look in the back sometimes there is a sund botton

yes we have had many in my shop and it is a bad panel if it really does not bother you then leave it alone, very hard to find a replacemnet screen

Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Most power cords for TVs have become universal so to speak, just note whether your TV has 2 or 3 prongs on the back where the cord attaches to the TV, then you should beable to find it locally at places such as, Walmart,Radio Shack,Best Buy,Sears, most electronics stores. Good Luck !

If you replaced the power supply module due to bad capacitors or blown parts, it could have damaged the main board when it went out.

wiil the set function ok after you do this? if so you will need a mainboard replacement if not then power board may have a bad capacitor on it the can shpe cap will have a domed top the values are on the side have it replaced or do it your self if your able

Let verify first to narrow down to where the problem can be. First, attach the powered PC speakers to the Audio Line out RCA jacks to see if you can get the sound OK there, if you do, then the problem can be in the power amp circuits, if the sound at RCA jacks is not OK, then the problem can be in the sound processor circuit.

powersupply.....

Sounds like a power supply problem,suggest you check for bad caps on board,probably deformed or bulged out

you have a bad cap in the power supply board these can like devices will have a puffed up top and the values are on the side of them change them or it out and you will be good to go

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Hi


Thanks for using FixYa. The reason of scratchy sound is due to high voltage. Please check the swollen/bulged capacitors. This issue arises due to failed capacitor in the power supply or an IC.

If you are well versed in electronics and have proper tools, you can diagnose, test and replace the swollen or bulged capacitors in the power supply. If still the issue persists, then you’ll need to replace 1000uf 35v which you can buy from the Radio Shack or any other nearest parts store.

Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

Rylee
