CCE	VCR-30X	Doesn't work	C806 (47 µf 100 v) e c807 (idem)
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	TVC-CCE	Tip	When changing the fly back, of the model that has 5 turns of wire around the core, generally from points a and b, to generate ref.horiz., the inversion of the position causes a strong black bar on one side of the image, or excess width.
CCE	INFORMAÇÕES TÉCNICAS	Ss9600, ss9900 and md2400 do 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	INFORMAÇÕES TÉCNICAS	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	INFORMAÇÕES TÉCNICAS	Hps 1492 / 2092 with the clock moving forward	When you receive any of these models above for repair, with the consumer complaining that the clock is running fast, just replace the IC 701 (micro) with the new IC code 140108714.
CCE	INFORMAÇÕES TÉCNICAS	Buh 515d horizontal output transistor	We noticed in some cases that the horizontal output transistor buh 515d (q404), used in hps 2092 televisions, shorts out without apparent cause, therefore, when you receive this model for repair with the shorted transistor, replace it with one of the transistors listed below: bu 2508 - code. 139999301, 2sd 1651 - code. 139999009, 2sd 1555 - code. 139999010 or 2sd 1878 - code. 139999264. Note: the buh 515d transistor (139999331) can be used on 14” televisions.
CCE	INFORMAÇÃO TÉCNICA	Fly-back tat 1405 a e tat 1405 b	The difference in the application of the fly-back tat 1405 a or b is the value of the inductor l402 (filament coil), according to the models listed below: - in televisions models hps 1470 p / q / r / s / t / u and hps 1480, the fly-back tat 1405 a (code 35.520.46.99) and the 20 µh inductor l402 (code 31.99170.27) are used. - in television models hps 1470 aa / bb / cc / dd / ee / ff and hps 1480 c, the fly-back tat 1405 b (code 35.52066.99) and the inductor l402 (code 31.99535.00) of 44 µh. Note: in current models, the value of the resistor r415 was also changed to 2k4 and the capacitor c413 to 100k / 250 v.
CCE	INFORMAÇÃO TÉCNICA	Whistle on stand-by power supply	- change the value of resistor r804 to 1k or 1k5. - if that doesn't help, replace the ci str 50103.
CCE	INFORMAÇÃO TÉCNICA	Noise (snoring) from the speaker on stand-by	Models - hps 1470 dd / ee / ff, hps 2070 u / v, hps 1480 and hps 2080 - change the value of resistor r610 from 1k to 220r. - remove capacitor c610; - change the c818 to 1000uf 16v
CCE	INFORMAÇÃO TÉCNICA	Adaptation of the microcontroller pca84c444 by pca84c644 used in several models of old televisions.	Due to the lack of microcontroller IC code CCE 140107014 (PCA84C444), we suggest that it be replaced by IC code CCE 140106914 (PCA84C644). for perfect operation, the following modifications must be made: 1. replace the pca84c444 directly with the pca84c644; 2. Replace memory IC PCF8581 to PCF8582 keeping pins 1 and 2 up; 3. invert pins 1 and 2 of the memory IC in the circuit, if necessary, lift the pins to make the connection with wires; Note: due to the fact that a new memory IC is being installed, all channel programming is lost, making it necessary to manually memorize the channels and the pp function.
CCE	INFORMAÇÃO TÉCNICA	Excessive heating of resistor r411 in stand-by – mandatory modification	On all hps 1402 and hps 2004 televisions, the following modification must be carried out: · remove the jc 16 “jumper” and include a 1uf/50 electrolytic capacitor in its position; · include a 22k resistor in parallel with a 1n4148 diode, between the base of transistor q401 and ground.
CCE	INFORMAÇÃO TÉCNICA	Transistor q402 (horizontal output) burns out without apparent cause – hps1402	On all model hps 1402, replace the value of resistor r411 from 2k2 / 3w to 4k7 / 3w.
CCE	HPS-2080E	Goes out after 3 hours of operation.	Antenna with weak signal, with drizzle.
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-2070	Inoperative, fuse open	D807,ic705 e ic801
CCE	HPS-2070		Changed q-702 and the problem solved.
CCE	HPS-2003	Television stopped	Shorted 12v line diodes together with shorted vertical output and open protection resistors, cause of fly back defects leaking voltage
CCE	HPS-1491	When turned on, image and sound appeared, after a few seconds the image disappeared and only the sound remained	Changed q-703 and the image returned normal.
