Watching TV and it shut off,,smelled like a transformer burnt up.
Pulled back off and power fuse was fine..see no signs of anything that got hot. Not lights will come on on front of TV.Is this TV worth repairing?
I'm guessing the power supply is bad and are they available ?
The unit was built in Sept 1998.

Re: TV quit no lights on front panel at all !
If you have Hitachi model number 50UX58B, 60UX58B, 50UX58K, 60UX58K, 50SBX78B or 60SBX78B and you have the following symptoms you may want to grab a repair kit from www.TvRepairKits.com. They have put together a kit that includes the parts and instructions to fix these models. This is a fairly common problem with the above model numbers. It is typically caused by a blown capacitor and pico fuse. Again, you can get a kit from the above address. Here are the symptoms...
Primary Symptom: No Audio or Video. Power light will come on briefly then shut off. Other Possible Symptoms : The green LEDs on the circuit board light up for a few seconds then turn off.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

if a power surge shut down the unit than a circuit, capacitor or fuse is blown and or burnt and you wont smell that most of the time and since it does have power fuse wasnt blown so a circuit -diode-capacitor is fried somewhere problem is common for an electricial damaged tv but to diagnose an electronic tech would need to tear it apart
First try to replace your power cable if it seperate from your TV and use another power socket to cofirm your cable is good and power socket. If your power cable is attached to the TV then just take the set to repaire centre and get it fixed.
Well, my first guess would be a blow fuse, did you check for that? But if you smelled something burning, then even if the fuse did blow, it failed to protect something; probably the main power transformer. That's a coil of wire in a sort of square shape that should be near the fuse. Its hard to tell if they're burnt sometimes, but it may need replacement. Please upload a few pictures so we can have a look too.
YOUR GOING TO NEED A NEW MICROWAVE . the cap may be bad but the real bad smell you have is most likely the HV tranformer , if the magntron shorts to ground there will be a small smell if you dont pick up on that and your microwave is set to run another few mins the transformer will overheat and burn , then the fuse blows and the controls shut down . the end result , you have more parts bad than you have good . if you google " GE SPACEMAKER MICROWAVE FIRE ' you will see your not the only one , its getting to be COMMON . good luck
It's most likely the low voltage transformer that's part of the circuit board or a blown trace on the board. The HV transformer would only burn and smell if the unit was in a cook cycle.
The complete board assembly is only around $80. If you're really handy, you can order just the little transformer, but you'd have to remove (unsolder) the old one and install (resolder) the new one on. The circuit board is one assembly and it takes all of 30 minutes or less to replace from start to finish.

If the fuse you replaced is a different rating to the one that was originally in your set then go out and get the correct fuse (get a couple)and try that. If you still have no joy then the most likely problem will be a failed transformer in the power supply - sometimes you may be able to see burnt areas on the surface of the transformer windings although these do not always indicate a problem. a short in the transformer can be fixed in many cases, but the most economical way to repair this type of problem is to replace the transformer with the correct type (usually readily available from electronics/TV repair shops.
The fact that you say it sparked at the plug is a little unusual, and could indicate a problem solely in the plug and power cord itself, easily replaced if you want to verify this. If you are competent to use a multimeter then a quick continuity test on the power cord would soon tell you if the short is in the supply cable/plug itself.
