amigo.não compensa comprar display.e muito caro.um display de 32 sai na faixa de 500,600 reais.da de quarente bem mais.

todas tvs que pego com tela quebrada compro para retirar placas

Bom Dia, Pinokio, estou com o mesmo problema; fiz um orçamento alto (650) para o cliente explicando que demorava para achar a peça, o cliente..............aceitou........  agora me acho com o dever de consertar.

ate o momento não achei  a tela., tem alguma seggestão? muito obrigado.

VDD

VDD is the logic supply input for the scan driver.

VON

Gate-On Supply.VON is the positive supplyvoltage for the CKV_,CKVB_,and STVP high -voltage driver outputs.

VOFF Gate-Off Supply.

VOFFis the negative supply voltage for the CKV_,CKVB_,and STVP high-voltage drive outputs. STV Vertical Sync Input.The rising edge of STV begins a frame of data.The STV input is used to generate the high-voltage STVP output. CPV1 Vertical Clock-Pulse Input.

CPV1 controls thetiming of the CKV1 and CKVB1 outputs, which change state (by first sharing  charge) on its falling edge. CPV2 Vertical Clock-Pulse Input.

CPV2 controls the timing of the CKV2 and CKVB2 outputs, which change state(by first sharing charge)on its falling edge.

ENE nables the MAX17121. DriveEN

high to startup the MAX17121 after a delaytime, which is set by a capacitor at DLY. CKVB1 High-Voltage Scan-Drive Output.

CKVB1 is the inverse of CKV1 during activestates and is high impedance whenever CKV1 is high impedance. CKVB2 High-Voltage Scan-Drive Output. CKVB2 is the inverse of CKV2 during active states and is high impedance whenever CKV2 is high impedance. CKVBCS2 CKVB2Charge-Sharing Connection. CKVBCS2 connects to CKVCS2 whenever CPV2 and STV are both low (to make CKV2 and CKVB2 highimpedance) to allow CKV2 to connect to CKVB2,sharing charge between the capacitive loads on the set  outputs. CKVCS2 CKV2Charge-Sharing Connection. CKVCS2 connects to CKVBCS2 whenever CPV2 and STV are both low(to make CKV2 andCKVB2 high impedance) to allow CKVB2 to connect to CKV2,sharing charge between the capacitive loads on the set wo outputs. STVP High-Voltage Scan-Drive Output.STVP is connected to VOFF when STV is low and is connected to VON when   STV is high and CPV1 islow.When both STV and CPV1 are high, STVP is high impedance. DLY Startup Delay Setting .Connect a capacitor to adjust the delay DISH VOFF Discharge Connection. Pulling DISH below ground activates an internal connection between VOFF and GND,rapidly discharging the VOFF supply.Typically, DISH is capacitive connected to VDD,so that when VDD falls,VOFF is discharged. VCOM Operational Amplifier Output CKVHigh-Voltage,Gate-Pulse Output.When enabled,CKV toggles between it shigh state (connected to GON)and it slowstate(connected to GOFF)on each falling edge of theCPV input.Further, CKV is high impedance whenever CPV and OE are both low and whenever CPV is low and OE CON is high. CKV CSCKVCharge-Sharing Connection.CKVCS connects to CKV whenever CKV is high impedance to allow connection to CKVB,sharing charge between the capacitive loads on the set wo outputs. CKVB CSCKVB Charge-Sharing Connection.CKVBCS connects to CKVB whenever CKVB is high impedance to allow connection to CKV,sharing charge between the capacitive loads on these two outputs. CKVB High-Voltage, Gate-Pulse Output.CKVB is the inverse of CKV during active states and is high impedance whenever CKV is high impedance. STVPHigh- Voltage, Start-Pulse Output.STVP is low(connected to GOFF)whenever STV is low and is high(connected to GON)only when STV is high and CPV and OE are both low. When STV is high and either CPV or OE is high, STVP is high impedance. STV Vertical Sync Input. The rising edge of STV begins a frame of data.The STV input is used to generate the high-voltage STVP output. OECON Active-Low, Output-Enable Timing Input. OECON is driven by an RC-filtered version of the OE input signal.If OE remains high long enough for the resistor to charge the capacitor up to the OECON threshold,the OE signal is masked until OE goes low and the capacitoris discharged below the threshold through the resistor. OE Active-High, Gate-Pulse Output Enable. CKV and CKVB leave the high-impedance charge sharing state on the rising edge of OE. CPV Vertical Clock-Pulse Input. CPV controls the timing of the CKV and CKVB outputs that change state(by first sharing charge) on its falling edge. GND LogicGround

DISHGOFF Discharge Input. Pulling DISH below ground activates an internal connection between GOFF and GND,rapidly discharging th e GOFF supply. Typically, DISH is capacitively connected to IN,so that when VIN falls GOFF is discharged.

VDD Supply Input. Logic supply input for the VCOM calibrator. Bypass to GND through a minimum 0.1μF capacitor. WPN Active-Low, Write-Protect Input. When WPN is low, I2C commands are ignored and the VCOM calibrator settings cannot be modified.
