Make	Model	Symptom	Problem
CCE	2171	Hoarse sound	Alter r113 to 10r
CCE	2991	50v com 18v	Q409
CCE	HPS-2971	Noise in audio	C671
CCE	HPS2971	Hoarse sound	Alter r113 to 10r
CCE	VCR 90X	Device does not turn on	Display indicating the presence of tape in the compartment, accepts tape normally. This occurs because the video is programmed with a timer. When you eject the tape, you will see a clock symbol appear on the display. procedure: connect the power cable; place a virgin ribbon or one with the seal intact; press the time rec key on the remote control; the video will turn on; press menu...program... and delete them all using the reset button on the remote control;
CCE	VCR 90X	Display completely off or clock after making the adjustment does not change	Procedure: reset the device plug the device into the socket press the power key to turn on the device short circuit momentarily short pin 10 (by) of the ic901 located on the front panel to ground (the device will turn off) turn the device on again by pressing the power key follow the general procedures to adjust the clock.
CCE	SS9600, SS9900 E MD2400	Does not tune to FM stations above 107.7 MHz	When you receive any of these models for repair, which does not tune into a local station above the 107.7MHz frequency (e.g.: 107.9MHz), just replace the IC 401 (micro) with the new IC code 710100057 for the SS9600 model. or 710100037 for models ss9900 / md2400. Attention: - This replacement is specific to cases in which the radio does not tune in to a specific local station above 107.7 MHz. for any other type of problem related to the micro (ic 401), use the ic code 710100007 for the ss9600 model or 710100034 for the ss9900 / md2400 models.
CCE	CM 260CD	Does not accept the disc (ejecting the cd)	In this car radio model with CD, when it occurs that when inserting the disc into the compartment it is automatically ejected, the fault is not mechanical but rather in the 16.9344mhz cr02 crystal, connected to pins 71 and 72 of ic2 - saa7341, which stops oscillating, and is easy to detect using an oscilloscope or frequency meter. As it is an SMD component, its removal must be very careful and in its place the crystal code 421230399 must be placed, this being a conventional component but appropriate to the circuit.
CCE	HPS 2085 E TODOS QUE USAM O CI LA-7910	Channels go out of tune	Ceramic capacitor connected to pins 3 and 4 of the la 7910, check and replace if it is shorted
CCE	HPS 2070	TV stopped	Diode d807 or ic 705, also check components in the area.
CCE	HPS 1470	Everything works normally, all functions happen, when you put it on standby it emits a beeping sound from the speaker	Open or altered resistor r804.
CCE	HPS 1465	No sound and no image	Capacitor c- 413 330pf shorted
CCE	HPS 1430-R	Poor vertical deflection	Capacitor c-356 and capacitor c-357, if that doesn't work, change all the electrolytics in the vertical, it will work
CCE	HPS 14	Colorless television and no sound from speaker	Cause of the defect q-801, replace it with a new one.
CCE	HPS1415	No vertical sweep.	Firstly, notice that the resistor (r420) that powers the vertical output will be burnt or intermittent. test the (ic301) and note that it will probably be shorted. Replace it with a new IC and the resistor. the television will work again, but with little height in the image, if the resistor burns out again, remove the ci and check the voltage that powers it and 24v, if it is above, change the capacitor (c458) coupled to the tsh, and another resistor (r420), and the device will operate normally.
CCE	HPS2070.	Totally inoperative.	Checking and testing transistor (q402) you will see that it will be perfect. Then test the anode of the diode (d404) and you will see that the voltage found is + or - 100vdc. Then go to pin 1 of the tsh and you will find 0v. The diagram shows that the diode (d404) takes the voltage from the power supply (ic801) to pin 4, and through the tsh winding the voltage appears on pin 1 to supply the collector of (q402), the horizontal output circuit is inoperative. checking between pin 1 of the tsh and the collector of (q402) there are two capacitors (c409) and (c413), after turning them off the circuit voltage, finding +b of 115v. with this measurement we realize that one of the capacitors may be shorted . So we do the test and find the shorted (c413). make the change, and the voltage on pin 1 will return to normal, and the television will operate again.
CCE	HPS 1481	Height adjustment does not open the entire image, causing darkness at the top of the screen	C-607 causes excess noise in the +b of the vertical ci, without image and with sound, enlarging the screen, vertical closed was noticed, check r-315 of 1.8 m, another possibility is r 312=2.2r open.
CCE	HPS 2080F	103v supply goes low when turned on and returns to normal	When entering stand-by, check r 805, which when open prevents the str 50103 from triggering at the same frequency as the horizontal.
CCE	HPS 2981	Shaking sides	It turns on and works normally for a few minutes, then the sides start to knock and the power supply emits a noise, as if the horizontal frequency is out. I verified that the power supply drops from 120v to 102v when the defect occurs. the image has a little excess white, I checked, the abl line (r 413, r 414, c420, d201, r206) is ok. solution: change all the power supply capacitors
CCE	HPS 2070	Buzzing at the power supply, doesn't work.	The first defect was the shorted diode that powers the +b of the fly-back (replace with original). On the first attempt to turn on the TV, it turned on with a green screen and white trace lines. I turned off the TV once and then when I turned it back on, there was no sign of life. After a lot of searching, I found a bf485 instead of the 2sc2236 (horiz driver). I decided to remove it and found a minimum leakage from base to emitter on the scale of x1. Just replace it and that's it. osb.: just replace with another original (2sc2236)
