Question about Samsung TX-R2035 TV
Pictrue being Ok and there is no sound is your problem. It may be either fault to its speaker or it sound output Ic. You can be sure about which of this has got troubled by yourself. Keep your ear very close to the speaker side of your TV, and switch it "ON" bu "MAINS", not by remote control. If you can hear a "Thumb" sound or a "Hum" sound, you can make sure that your TVs speaker is OK. If there is no sound at al, it means that there is some fault to your TVs speaker. It can be due to a socket trouble also. If there is an earphone socket in front panel of your TV, just insert an earphone pin into it and check whether sound coming from it or not. If there is sound through earphone, and when it is unpluged, sound does not transfer to the speaker, means that socket has some trouble. Replacing it will solve the problem.
If you hear a "HUM" sound, as decribed earlier here, this may due to the Sound Output Ic inside the circuit borard of your TV. To rectify this fault, ypu have to open your tv, and locate the sound output ic. Just follow the speaker wire, and somewhere near it orginates from the mainboard, or other board, can locate it. Usually this IC will be screwed into a metal plate, inorder to radiate heat from it while working. Check for any loose solderings to its legs, that may also cause it to be nonfunctional. Anyway resolder its legs first by applying a little more solder, and check the result. If this also doesn't help, resolder it out from the board, and go for a same type and number. Replaceing it will solve the problem. Ok.
Take every precautions before you open your TV. Keep children away from you while you are working. Never allow to them even stand beside you, and allow an adult beside you as a pracationary measure, and as a helping hand. Keep AC power chord out of wall socket each time you make contact with the inner circuit board of your TV.
