Hello!
Now I'm trying to repair Mitsubishi 920SB model NUR1905STTKW !!! IC502(SLA5054) is shorted in FET1 and FET2. This IC is a simple FETs array working as S-correction switch. I changed С516(1u3/250V) С514(0u68/250V) and IC502(SLA5054) monitor is working, but there is poor horisontal linearity. Two left and two right squares in Nokia test are 18 mm wide but other squares are 22mm wide (1024x768@85). While changing the resolution problem persists. So, what I forgot to replace? Maybe SLA5054 I replaced is faulty? |

I do not have scheme. Capacities S-correction which does not connect SLA5054, are checked up? |

TE, thank you for your attention!
ECAP С539(4u7/250V) which is connecned parallel to С516 was faulty. Monitor is working OK. |
