Multiscan L5032LD - Wysokie napięcie wyłącza się po wymianie Q710 i rezystorów

Wymnieniłem Q710-FS10UM, R133, R134. Teraz wysokie startyje i wyłącza się po kilku minutach.
Bardzo grzeje się BU 2520 .
Ostygnie i znowu chodzi pare minut .

Cześć.
Sprawdź zasilanie - elki - pewnie do wymiany.
Pozdrawiam.

check storage coil near q710 - it may have shorted turns - in that case it will run also hot
next thing is what dariuszm2 was writting - you have to check/replace electrolitic capicator in b+ rail of PSU, especialy after that step-up dc/dc converter that q710 is part of
ofcourse this is based only on my knowledge about monitors and there is load of assumption in it, i didn't have such model on my bench

Hi Candle.Very nice to get answer in short time.
I am going to do your offers ..At first time BU2025 Sweep power burned and two serial resistor 3.3 ohm burned wich is on +B line of step up converter with T710 Mosfet.
İf I disconnect T710 step up Tr.screen opening but small and dark.,if I put T 710 again on circuits, again these parts burning.
As you offers to me there are some short circuits on some parts.
Thankyou again.Best wishes,ıf you have anymore info I will be waiting.
