T-con panel
Sziasztok! Grundig Vision3 26-3820 tipusú lcd-tv-hez keresek T-con panelt, Tipusa:26T04-C00. Javitási tippet is elfogadok. Az egész panel átlett már forrasztva. Forrasztás után 1-2 órát megy, majd átvált a kép fehérre. Köszi: Hege.
Gaba KL32CS62Q lcd
Tisztelt Kollégák! Vélemény szeretnék kérni. Képtartalomtól függően cifrázza.Az lcd tetején kb.2 cm-es sávban látható kép.A t-con csatlakozót kihúzva homogén szürke a képernyő. Gondolom a vezérléssel lehet gond. Control boardon a scaler fél perc után 80C fok. Mellékelek néhány fotót. Köszi, üdv, kovácsa
Horizon 24HL7123H hag promléma
Sziasztok Fórumtagok!
Adott készülék produkcioja hogy a hangerőt saját magától huzza lefele attól függetlenül hogy a távirányító a közelben sincs.
A tápban nem látok púpos kondit pedig az szokott ilyet csinálni. Lehet ezt resetelni? Így még monitornak sem jó mert ott van az elején a hangszóró jel mintha nyomnám a távot folyamatosan. Ötlet? Vagy valaki találkozott már ilyennel? Előre is köszi a válaszokat!
közben meglett az alaplap képe meg tipusa. Feltőltöttem     vestel 17mb140

Méregetés közben a 12volt csak 11.45volt. ez okozhatja?
JVC AV-21FMG4G Chassis SCW-1362A blinks continuously after three failing power on attempts
JVC AV-21FMG4G Chassis SCW-1362A CRT TV blinks continuously after three failing power on attempts.
According to the customer, the upper portion of the screen started shrinking with horizontal lines, then ended with a single thin horizontal line.
This suspects the vertical drive section to be problematic. No vertical output though vertical in put is OK. After conducting an ESR check for capacitors in the vertical section, C428 (100uF 35V), connecting VCC1 with Pump-up pin # 3 of the IC, it measured 1200pF. It was replaced but still no vertical output. So changed the vertical IC401 (TDA78040), and the output appeared, but still blinks after three failing start-ups. I, m suspecting the corrupt EEPROM data.
CPU: TDA11010H / N1D00
