Medion MD30045 HDM9L-V5.2 Picture freezes after 5-6h

[Foppel]

Dear Badcaps Members,

i repaired a Medion MD30045 37" Flat Screen TV. The Picture freezes after 5-6h power on. I use my oscilloscope to check the voltage regulators on the left hand side. There was a lot of ripple noise at the output of the upper LT1084. I desoldered the two filter caps (47uF/16V/105°) and i measured a ESR of 9 Ohms. I replaced all the caps on the left hand side an now the ripple is gone

Board: HDM9L-V5.2
Power Supply: FSP270-4M02 P/N: 3BS0134113GP
Inverter: DARFON V183 4H.V1838.411 /B1

Thanks a lot Foppel, it was very helpful for me ! My Medion tv picture, after 20-30 min power on, has a ripple noise upon image, after replacing the two capacitors 47/16v, the image is clear.sorry for my engl.
