TVs SHARP series silver box
Picture|Thosiba
TOSHIBA-2545DE (TA8808)
• Regulators and relays are not stable (PUM-up): Check out the Horizontal oscillator, and replace the crystal with the 500F2 503F30 usual
THOSIBA-20N3XE (Bomba)
• The color is lost, the normal picture: Replace IC TB1231
THOSIBA-1450XNE (dramatic Vision)
• Regulators are unstable: Check D873 (16V zener) on regulator
THOSIBA-2955DE
• Auto Search is good, no color pictures, sounds gorok: Check Adjust L671 in SIF module
TOSHIBA-2840XH
• Vertical defect resistor, capacitor elco, IC, nice all: Check out Vertical driver feedback voltage is normally 3-4 volt
Samsung-Cb
SAMSUNG-CB3339Z
• Blanking: check the voltage 5v (7805)
SAMSUNG-BIO-CB3366Z
• Blanking (normal Vcc): replace the chroma IC M52309SP
SAMSUNG-CB2039Z
• Tuning no channel (33v, VT Normal): 12v voltage check
SAMSUNG-CB3862X
• Pictures open ditenga about 5cm, IC Vertical nice: G anti elco vertically out 1000uf/35v
SAMSUNG-CB3366Z
• SMR 40 000 Damaged, damaged again after the change: replace the first driver module HIS 6169
Check and replace
Goldstar-Soudmax
Color is sometimes missing: check and replace cramic pin 11 of IC TDA8690
Goldstar-C14D22
No sound, standard tuning does not stop: check Q06 (C3198)
Goldstar-C14D22
Standby, in turn it can not, led is flashing: check 6v8 zener diodes in the PSU, if distar led is dead: check SE 110
Goldstar-CA14A95C
Standard tuning does not stop: replace Ucom GS8334-02B
Goldstar-CA14A62
Image thinning replaced PIF Stay the same: check Z201 (CF5, 5MHz)
Goldstar-CF14D20
Fig sometimes colored sometimes not: open the base legs Q07 R73
Goldstar-CF14D20
In the star led the flame, continue to die (no standby): check pin 9 S6707, if not stable (PUM up) check FR813 (1ohm) and ZD803 (9V1)
Goldstar-CBS4821
There is no color, when there are new hot Delay IC color: replace the MC144111. To test it go to pin 4 and hold color.
Panel presets do not work: go to pin 6
Goldstar-CF14A170D
No sound IC LA7555 Good Audio): check L201 (SIF 6.0 MHz) and the damaged capacitor (82pf)
Goldstar-Soudmax
Blanking, RGB VCC nice: replace TA8690
Goldstar-Soudmax
Standby with the position of blinking LED lights: replace diode RU2k near STR 6707 with D IN4007 also replace: C330 (470uf/35v)
Goldstar / LG
Often turns itself to standby, if the remote at the switch on the TV to life again, but went back to standby after a few hours: replace Elco Driver Horizontal (10uf/100v)
repair and easy
PANASONIC-TC20T8
Regulators did not work (dead): check Q8 1 (C5253/C4804) and Q805 (A1512/A733)
PANASONIC (AN5601)
There is no color, in Fine tuning is: check Trans amplifier delay (C1685) not delay line
PANASONIC-TC1613R
As if tuning slide (slip) and not syncron, good sound: check R125 (3k3) 1k2 replace with
PANASONIC-TC2088DX
The contrast is not working, sometimes appears a vertical line, a nice picture: check the ABL resistor (37K)
PANASONIC-TC1450
Blanking and protectionism: replace the AN 5600
No sound: check the Q1112, Q1113 (N4212) and change C114
PANASONIC-TC2088
Bright, contras, the color of the OSD function is not normal: Check the ABL resistor (63k)

quick and easy
POLITRON-GM1483
• OSD does not exist: please go to the R723 and D732
POLITRON-P in P
• Tuning geses and blanking, OSD nice: check tuner (digital 5v) damaged one of them
POLITRON (Regulator TDA8380)
• B + is not stable (PUM-up): increase in the priner Filter 15V regulator so 2200uf
POLITRON-GM1492
• Tuner Menual not stop: Replace Transformer AFT with E08L
POLITRON (AN5435 = TDA3565)
• Vertical can not be silent, V.hight not optimal: instead of AN5435 and R127 (13k)
POLITRON-BB1740
• As if tuning slide, VIF is good BI continues: check Transistor Band switch T708(BC548)
POLITRON-PN20123K
• PROTEK, distar live and die (Vcc good): replace IC 4558 near the amplifier Vertical
POLITRON-GM1490
• Phase Horizontal shear (no black line) is almost to center: check R449 (68) to pin12
POLITRON-LFS1465
• Led channel flame all, the presets are not support: check R18 (10k) on pin 19(UPC 1363)
POLITRON-PN14123KAG
• Can not star, there is no horizontal oscillator, VCC nice: replace TDA 8841
POLITRON-Lawas
• thick black lines up and down both the position of the AV and in the Channel:replace Plyback (FBT)
