Make	Model	Symptom	Problem
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)
CCE	HPS 2003	Burning horizontal outlet	The defect was the horizontal outlet itself, I was forced to buy an original from an authorized dealer because the 2 (two) I bought in stores were of poor quality. the transistor is the bu2508dx.
CCE	HPS 2080	Heating up a lot c428 until it explodes	The problem was the flay back, which was causing the c428 to explode
CCE	HPS 1470 / 2070 - SéRIES P / Q / R / S / T / U / V	Dark stripe on the side, poor video and chroma	Check r427 (4k7 changed), r403 to 405, d401, c401, ic402; - reverse connection of the wire wound on the fly-back ferrite (± 4 turns).
CCE	HPS 1470 / 2070 - SéRIES P / Q / R / S / T / U / V	Vertical closed	Verificar sw201, c301 a c308, r301, r312/313, d301/302, ic301.
CCE	HPS 1470 / 2070 - SéRIES P / Q / R / S / T / U / V	Reduced frame on four sides	Check r501 according to the version of ic501 tda8361, being: 47k for version (3y) or 8k2 for version (4x and 5); - check crystal x501.
CCE	HPS 1470 / 2070 - SéRIES P / Q / R / S / T / U / V	TV turns off by itself or after turning it off, via the keyboard or c.r., it won't turn on again	By turning it off and on again via the AC cable, the TV starts working again. This problem occurs in locations with a low AC network. - replace the 2k7 - 10w resistor r806 with 1k5 - 10 or 15w; Attention: - in some TV's there are 3 resistors of 8k2 - 3w in place of the resistor of 2k7 - 10w. Solder the resistor well away from the PCI. - replace transistor q704.
CCE	HPS 1470 / 2070 - SéRIES P / Q / R / S / T / U / V	Improve self-programming	Change the value of resistor r204 from 4k7 to 6k8 ½ w - metal film
CCE	HPS 1470 / 2070 - SéRIES P / Q / R / S / T / U / V	Improve character intensity	Change the value of the resistors: r744 from 4k7 to 3k3 ½ w - metal film r745 from 4k7 to 6k8 ½ w - metal film r746 from 4k7 to 5k6 ½ w - metal film
CCE	HPS 1470 / 2070 - SéRIES P / Q / R / S / T / U / V	Optimize reset circuit of ic 701 (micro)	Does not tune channels - change the value of capacitor c718 from 1mf/100v to 2.2mf/100v; - change the value of resistor r740 from 220r to 150r ½ w - metal film.
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	HPS 1470 DD / EE / FF, HPS 2070 U / V, HPS 1480 E HPS 2080	Noise (snoring) from the speaker on stand-by	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	HPS 1403 / 2003 / 2006 / 2706	Does not turn on and the stand-by LED is blinking	Capacitor c826 (code 491010104) leaking
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	HPS1402	Transistor q402 (horizontal output) burns out without apparent cause	On all model hps 1402, replace the value of resistor r411 from 2k2 / 3w to 4k7 / 3w.
CCE	HPS 1492 / 2092	With the clock moving forward	When you receive any of the above models for repair, with the consumer complaining that the clock is running fast, just replace the IC 701 (micro) with the new IC.
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 - 2sd 1651 - 2sd 1555 or 2sd 1878 note: the buh 515d transistor can be used in 14" televisions.
