[gara]

Hi , I have Hanseatic LC20TD with board PLVM01 rev no. 05 . My TV dont power up , only stand by mode with red light from LED. ( I think this is same models DMTECH LT20DV2 and Rolsen RL-20D20D ) . I was check all fuses and its OK. LM2576T3.3 switcher and voltage regulator have V in , have ON/OFF signal when I press POWER button , but dont have OUTPUT 3.3 V and nothing have on Feedback ! What you thing ,what is problem , what I can do next ?
Have someone service manua for that TV ?
Thanks and best regards....

Check for power supply capacitors with swollen tops,they are usually35volt.1000uf.
