Witam!
Mruga mi dioda 4 razy i mam uszkodzony moduł Y TNPA5066AB. Po oględzinach stwierdziłem zwarcie diody o nazwie FU20 TM5S....co to za dioda i co mozna za nią wstawić? Proszę o poradę.

4 Blinks SOS:
- regulation issues with any of the voltages output from the power supply
- wrong diagnostic by the A board

After I replaced the SS board with SN completly disconnected I got 6 blinks, when I checked Vsus on SS it was 60-70V and going down

"The TC-P42X2/C2 series have an energy recovery circuit in the SN boards. This circuit monitors the scan board output and the sustain board output. Any abnormality on this circuit will trigger the 6 blinks code. If SC20 is disconnected or is not seated properly, the TV shuts down with 6 blinks."
