I got a mitsubishi 50604, it was working fine and it shut off, now it wont come on, we replaced a blown fuse and now it keeps blowing fuses and wont come on
SOURCE: blown 4 amp fuse twice
ok appaloosa! is the fuse blowned again? if blow you have fault unregulated power section, you have defective parts like.. leak degausing or defective diodes or capacitor and or regulator IC. 2nd. defective horizontal output. if not blow the fuse u have fault oscillation!

Arynsunn,
Thanks to you, I was able to find the solution to my problem.
Have you tried using the correct Fusible Link? I noticed in another post that you said you replaced it with a 500ma instead of the 400ma. I had the same original problem as you and found the exact fuseible links at www.mouser.com. Part# 576-3960400000 Littelfuse Fuses - A 125V UL TL LL .400A . They are only 55 cents plus shipping. I bought 5 for under $10 shipped. Only took 2 days to get them. My TV works like a charm now! I too thought I may need to replace the IC's but thankfully my TV is working fine. If you did need to replace them, where were they located? I couldn't find any stk IC's inside either and the IC's on the heat sinks are all small. Just trying to be proactive, in case I ever need to replace them.
SOURCE: blown fuse
Most likely there was a power event (surge, brownout, ect) that caused the power supply to fail in the TV causing the fuse to blow. you will need to have someone come and look at the unit and give you an estimate. If you keep putting fuses in and blowing them you could actually be causing more damage.

How tv functioned when you power it up after fuse replacement or tv gave some problem in sound or picture?
