"IMPORTANT! Select a forum topic name that is descriptive, more precisely matched to which you're writing about. A possible good name
eg, ORION LCD-2 17MB12 PT26S chassis, the power supply for will not start

Hi all,
i want to repair a power board : BEKO XLA194-03.
T2001 ( MOSFET P9NK70ZFP ) is devinitively defective.
See pic. 1
i downloaded this manual: https://elektrotanya.com/beko_xla194-03_power.pdf/download.html
but the repair list ( https://elektrotanya.com/files/forum/2014/08/Beko%20XLA194-03%20PSU%20repair%20kit.txt) does not correspond to the link above.
The names of the elements are completely different.
But the names of elements from my board are the same like the manual ( link above).
Knows someone which elements I must exchange, related to schematics in the manual?
Best regards Dietmar
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
EEPROM: 24C16A
Any one with EEPROM dump for this model or any help please?
Sziasztok!
Samsung Ue37c5000 készülék ma kikapcsolás után többet nem kapcsol be csak a power led villog.
Ezt megelőzően csináltam a service menüben egy factory resetet, mert valamiért nem tudtam a mindig tv-t beprogramozni és gondoltam hátha el van állítva valami.
Nem tudom van e összefüggés, mert ezután még ment a tv és ki-be is volt kapcsolva, aztán egyszer csak már nem kapcsolt be többet.
Tudna valaki segíteni?
Köszi!
Tamás
