SOURCE: picture shrinks horizontally every few seconds.

You are changing parts in the wrong circuit. The problem is in the vertical circuit. Look for the vertical IC and resolder the pins first. It should be an LA7837 or something similar. Also, check the 100ufd and 47ufd caps in the same circuit.

Keep us posted.

Resetting the progressive scan mode on an LG lh-d2645 home theatre system


the above is correct but you need to have the dvd player on with no disc in so "no disk" is shown on the front display. then hold down the stop button for 5 secs to reset the display mode back.

Picture Shrinks


It is in the power supply or I would guess most likly in the horizontal sweep section of the tV set. MOST of the time, if the power supply is going lower in voltage, the set will shrink in width,BUT will also shrink in vertical size. If this is not happening, then I would say it is in the horizontal drive circuit. This is not a circuit a user should be experimenting with, as this is the HIGH VOLTAGE circuit and can pack a mean punch! Please if the sets less the 4 to 5 years old you may want to concider an estimate or replacing the set. Its all up to you. GOOD LUCK
