Mitsubushi
	Tech Tip #76758 for Mitsubushi Power Supply If the Mitsubushi power supply module has been repaired and tested and you still have problems with the set, the deflection module may also be defective. In most cases, there will be no damage to the repaired power supply by the defective deflection module. PTS offers repair of the deflection module.
Philips
	Tech Tip #76763 for Philips APD This Large Signal Panel may need a vertical size adjustment made in the service mode. To enter this mode press the following buttons on the remote transmitter in this order: 0-6-2-5-9-6-MENU. Using the left and right cursor keys select the register description “picture ht”. Using the up and down cursor keys adjust the value until the picture fills out the screen. Press, “power” to exit. The TV will save the information and turn off.
	Tech Tip #76733-5/95 for Philips Power and Deflection Modules - APW007, APW008, APW009, APW010, 704978, 705442, A10320, A10326, 704979, A10338 and 705444 Before applying power after replacing a power supply or deflection module in a PTV100, 200, 300, 310 or 325 Chassis, check the other power supply or deflection module that is not being replaced for shorted components. Shorted components on the module that is not being replaced can cause the new module to fail resulting in “dead set”.
RCA
	No Audio Suggestion: Ensure the “External/Internal Audio Switch” is in the correct position. Suggestion: Ensure the speaker wires are properly connected.
	Projection Splitter Blocks Suggestion: If the unit is shutting down; check the ends of your anode leads for carbon build up. This is an indication that the splitter block is defective. Suggestion: If the unit is arcing; ensure the anode leads are “seated” properly, i.e., fully seated, wires not bent, brown rubber o’rings left in splitter and preventing proper connection.
Sony
	Tech Tip #76759 for Sony Convergence Board A-1346-296 SYMPTOM - Convergence problems after repair of the convergence board. It may be necessary to have the “M” board repaired. This board has the microprocessor and eprom that controls and stores convergence data. PTS offers repair of this board (A-1306-493-A, 497-A).
Zenith
	Tech Tip #76740 5/01 for C6, C8, C10 and C11 Chassis - 9-1200, 1300, 1400, 1500 Series Modules Before installing the replacement module, the picture tube should be checked. A defective picture tube ( such as a G1 short) may cause a failure in the power supply section.
	Tech Tip #76732-6/96 for C6, C8, C10 and C11 Chassis - 9-1200, 1300, 1400, 1500 Series Modules SYMPTOM - Chassis appears to have no remote functions but works OK from the keyboard. The Chassis may need to have one setting in the service menu changed. To access the service menu from the front panel; press and hold the “Menu” key until the menu disappears. Then without delay simultaneously press the “Adj Right” and “Channel Up”. Use “Select Up/Down” key to toggle through the menu until you have highlighted “Zen/PL”. Press the “Adjust” key to change the status of the Zenith/Private Label function. Press “Enter” to exit the service menu (You may have to press “Enter” twice on some models). Please note it is recommended that no other adjustments be made in the service menu as these are factory settings and you may cause other problems if you attempt to change other settings.
	Tech Tip #76667 10/90 Installation Instructions for 9-160-05 and 9-160-06 This module is FRAGILE!! Careful handling can prevent call backs. When replacing the 9-160 module, precautions must be taken to avoid damage because of other problems that may exist. The 9-160 serves as a low and high voltage power supply that is developed from the horizontal output transformer. A short circuit from another module powered from these supplies can destroy the horizontal output transistor or rectifiers on the 9-160. Clean all plugs that connect to the edge of the 9-160 with a rubber eraser. Ensure the pins in these plugs are above the surface of the plug. This will prevent a possible open or intermittent caused by dirt or a sprung pin and appear to be a defective module. Because the television is tied to AC Ground it makes it a hot chassis. An isolation transformer must be used when servicing the set. This will prevent damage to modules and/or ground paths in the television set or test equipment. It will also help to prevent a shock hazard. Before connecting full power to the chassis, use a variac and set the AC to 66V. Use an oscilloscope and set up to check the waveform on Pin 3 of Plug 3C. Be prepared to immediately remove power from the set if you do not see a 1.8 volt peak-to-peak horizontal frequency waveform. If that waveform is not present, repeat the procedure for Pin 4 of Plug 1B and look for a 2 volt peak-to peak waveform. If either waveform is incorrect, it indicates a failure on the 9-151 or the 9-152 which will cause the 9-160 to fail. Check the 95V ADJ (RX3312). This adjustment, if incorrectly adjusted, can cause the set to not Start Up or Folding Pix near center of screen. A Battery Powered Voltmeter must be used since a portion of the 9-160 is tied to AC Ground (Hot Ground). This adjustment is critical and the following procedure must be followed: With the TV unplugged, connect a DC voltmeter across C3321. Plug into variac transformer ad adjust line voltage to 120 vac. Adjust brightness and picture controls to minimum. Adjust RX3312 until 95 vdc appears across C3321. With this setting, specifications for filament voltage and high voltage will be within tolerance. If your set has Plug 3W, its circuitry has been replaced on the 9-160. Tape up this plug and dress it out of the way. On “N” lines sets with the 175-5128 tuner, if you are substituting the 9-160-05 for the 9-160-06 for the 9-160-09, two connections on the tuner have been omitted. They are a yellow wire with red male plug and a white wire with white female plug. Tape these up and dress them out of the way. A 9-160-05 MAY NOT be used for a 9-160-06 or vice versa. The pin arrangement, the flyback transformer, and H-V shutdown circuits are different. The 9-160-05 is a universal replacement module for: 9-160, 9-160-03, and 9-160-08. The 9-160-06 is a universal replacement module for: 9-160-02, 9-160-04, and 9-160-09.
	No Picture Suggestion: Any Chassis with a “Setup Switch” on the CRT board will exhibit this problem if the switch is left in the “Setup” position.
	No Audio Suggestion: A plug in Jack/Pack module can cause this problem. Suggestion: Ensure the “External/Internal Audio Switch” is in the correct position. Suggestion: Ensure the speaker wires are properly connected.
	No Video Suggestion: This problem can be cause by a PIP module.
