Lots going on punitive damages that are generally the same for all TV brands. For example in the case of damage to television as star of life and death, Raster No, not the full picture, Figure shrink right and left, Blooming, No Raster, Bright, contras do not work and others.Here's the trick to check the rapid decay television for many brands
How to measure the voltage of the TV * Connect the black wire (-) to negative ground PCB transformer secondary section Switching (for TV china) or tuck in the wire without wrapping the CRT tube. * The red cable to the following point: - Voltage 180v: Legs + elko 250V at PCB RGB. - Voltage 110v / 130V: B + Flyback / FBT or foot Elco 160v + - Voltage 12v: Leg rightmost IC 7812. - Voltage 5v: Leg rightmost IC 7805. - Voltage 33V: B + Foot Tuner blog ___________________ Checking Rapid Damage Television, various brands: AKARI-IC 14M88R Regulator not functioning. Check transitor voltage optocoupler. AKARI-IC 1437RMD Regulators did not work.

Horizontal oscillator checks out, replace the crystal with a 500F2 503F30. Thosiba-20N3XE (BOMBA) Color disappeared, normal picture. Replace IC TB1231. Thosiba-1450XNE (Dramatic Vision) Regulator is not stable: Check D873 (zener 16v) regulator. Thosiba-2955DE Automatic search good, colorless images, sounds ugly Check Adjust L671 in SIF module TOSHIBA-2840XH Vertical defects. Check resistor, capacitor elco, IC, driver feedback Vertical normal stress out 34 volts Tohsiba bomba 21 " TV standby itself, sometimes can star Check the voltage at the B + regulator, if not replace the optocoupler normal.
CHINESE TV Regulators silent even without load, check the capacitor in the power base (15N) Chinese TV Masda. The green color is lost, the voltage khatoda R, G, B normal and balanced but voltage on R-out, G-and B-out out of the IC LA76818 unbalanced. Replace IC LA76818 ********* Damage in general on China TV - If TR often die due to very hot try changing the supporting components, probably worn elco. - If the voltage rises, try to replace R in the string of Adjustment Reg. 100K, 150K, 47K R - Voltage slowly rise, try to replace TR A1015. - TV can sometimes be life and often drop, image narrow and frivolous, try to replace the trimpot 2K2. - TV can be ON and the screen flash but then the screen shut down briefly, then turns back so keep alternately try to replace diode IN4148 - The voltage does not exist or does not appear, nor the voltage drop and no sound on the inverter transformer, or TR also always try to replace broken after replacement optocoupler and C 2kV.
- The TV is on normal, TR sudden death but not hot, try changing R1K2 and C dumper (2000kv). - Images can not be saved / in auto search, try changing C 60pf or 30pf but can also exist in data errors or VIF38 VIF.SYS.SW, 9. - Picture is not synchronous, switch 50V 1uF elco coupling the IC picture. - TV and can not just standby ON, no OSD, remote does not work, try to check IC eeprom - Colors can be lost due to damage data or try to replace elco 0.47 uF 50V parts croma - TV only blue screen no OSD, one color is missing, check the IC images - No OSD, the TV does not work. try to check R 150K and TR C1815 for vertical sync. - Picture is only a horizontal, vertical IC checks - Flyback broken: TR Short horizontal participate, so the B + voltage drop, Flayback issued fire, R charred. Damage Goldstar TV - STR S6707 often die / short, check elco 35V220uf (suply STR), R 37 ohm - Voltage drop / pump-up, check the IC SE110/115. Opto coupler PC817 - B + Drop and will not turn on, replace elco B + 160V220UF and 100uF. - Tv continues to be lit briefly Standby position, check all elco drive voltage, horizontal oscillator
- Image shift, can not save automatically, check images and AFT coil, replace C ceramic 60pf - Only the OSD, picture and no sound, check the IC switching AV / TV tuner LA7222 close. - Picture bloming or try to replace some of the light to voltage 180v elco video - TV Channel is always on top, so changing the function button panel, Memory ICs usually broken. Disturbances in Tuner Disorders of the tuner probably happens is that the channel would not locked and that only certain channels. Let you do find a semi auto, observe whether to stop or continue the program or not. If the press can not be unlocked then there is damage to the transformer IF components (eg, 6019, 498U, Eo8L, 9074 and others). If the broadcast can be stopped and locked with both the damage to his TUNER. Try changing the IF then check back and see if the program is good or not, or if it can be locked. If there is a change of color and sound means Tuner has been damaged. Voltage at Tuner also must fit and stable. Disorders of the IF components make TV can not lock TV channels, interference with 33V voltage shift will make the broadcast. Besides disruption also caused tuner IC program does not work.
So the trick to check the rapid decay of Television and some damage problems that often occur on the TV and repair solutions. Carefully inspect each component associated with the damage, including solder that may have come loose and bouncy. A few of the first reviews I quickly checked Tricks Television damage. New!
