FS7 		With sound and sometimes without sound. Mute circuit: measure the voltage at pin 56 of q501 and check if in the mute on condition it is equal to 5.0vdc and mute off is equal to 0.0 vdc and if the transistors q611/q631 go into cut-off and saturation. - if the switching on pin 56 of q501 is not performed when disabling the mute signal; replace micro q501 If you don't want or can replace q501, remove the base from q611 and q630. jr_TEC

FS7 		Hoarse sound and sometimes no sound. Don't waste time! first change the cg10(47uf/25v) connected to pin 19 of the qg01(mts decoder) as it may be exhausted and then to make everything ok, release the base of q611 and q631 and just be happy. jr_TEC

Noise at the power supply and after 2 minutes the image turns green +b filter capacitor (47μ x 200v) was dry. One of 100μ x 160v can be placed and it will be fine. Replace the c-311 power supply capacitor. good luck friends. Giovani

TV turns on, has picture, but no sound "sdin" signal that arrives at pin 22 of the audio ci tas5707 coming from the non-existent micro. (no audio input signal on the ci) Changing the microprocessor or changing the entire board because the micro and BGA solder. Ivan Bustamante

White stripe at the top of the screen, 4 fingers with a transparent stripe at the top. I changed all the elco covers around the vertical integrated circuit, lastly I changed the stv8172a vertical IC but it didn't solve it! Then I lifted all the diodes and measured, then one of them the gr350 - erb12-02 was open, I replaced it with the 1n4007, it was perfect, the white transparent band at the top of the screen ended!!!
