I'm having vertical problem at bottom i'ts missing about two inches at bottom every thing else work's perfect. i resoldered the vertical TDA7052B Found about 5 caps low esr changed them but still have the problem. I want to know if this model has a code that i could enter to adjust vertical. or just change the vertical ic.
1. To enter the Service Alignment Mode (SAM), press the following key sequence on the remote control transmitter: 0-6-2-5-9-6-Status. 2. From the top level SAM menu, use the Menu Up/Down keys to highlight the Geometry sub menu. 3. Use the Menu Left/Right keys to enter the Geometry sub menu. 6. Using the cursor up/down keys, select VAM from the Geometry sub-menu, and use the Menu Right key to increase the value to obtain a slight overscan. 7. If other Geometry adjustments are needed, proceed to the necessary adjustment using the Menu Up/Down buttons.
4. In the Geometry sub-menu, use the Menu Up/Down buttons to select VAM.
5. Using the Menu Left/Right keys, adjust VSH so that the horizontal bar is properly centered, top to bottom.
8. Upon completion of Geometry adjustments, press the Menu button to return to the top level SAM menu.
9. To exit the Service Alignment Mode, turn the set off with the Power button on the remote control.
