The TV has an ok audio output and all voltages, but tsound is no sound. This version of the TV has the IC851 analog audio equalizer on the board near the varicap. | Ci defective equalizer, replace or if tsound is no other add the following components to the board (q801- brc1815,r804-470Ω,r739-56kΩ,r740-1kΩ) the jumper j801 and j802. | The TV returns the sound normally with the audio equalizer acting if the ci is replaced, if the modification is made the sound returns to normal (volume acting) but the equalizer no longer works...

No image appears in analog mode (vga) | Http://downloadcenter.samsung.com/content/fm/201203/20120302184541530/samsungfirmwareupdater_1.1.07_120227.exe, copy the link and paste it into ggogle, after doing this you will download a program, when you download the file run it, with the monitor connected via the vga cable to the computer note: the monitor must be on, even without an image), after a few seconds or minutes the monitor will be updated via the vga cable itself | reginaldo moronte,eletronica junior caldas novas | |

TV turned on, but without sound and with the vertical trying to close at the top of the image. | Bad capacitors (in the audio the c613, 220uf/25v and in the vertical c308, 100uf/25v) | Replace with new or in good condition. If you don't have 25v, you can use one with a slightly higher voltage. After that, the TV will return to normal operation. | Tiago C. Neves |
