20 Most Recent Hitachi 60UX58B 60" Rear Projection Television Questions & Answers

Check your TV level ... it must stand on a firm foundation ... it wobbles because your floor shakes - reduce the shaking by improving its contact with the floor.

You of course should first look at the fuse inside.Some of these sets have a cap and a fuse associated with it that fail, did you ask this question here a few days ago? I can repeat my answer but if you already have that answer I do not want to tell you something that you already tried and did not help.

Linda,
A VERY common problem with this unit is a small blue disc cap C707 (102 @ 2kv) tucked in front of the horizontal output transistor. It usually has a small pin hole burned in it when it goes out. The cap is actaully part of the scan circuit and it changes in value over time and becomes unstable then opens, usually taking with it E994 a small pico fuse.
I wouldn't spray too much duster in there for all the dust it will create. You'll be dusting the house for days. But it won't hurt using a can of duster or air to blow it out if you want...

Well this is a pretty classic problem with the Power Supply, what's happening is that the "Protection mechanism" is be activated,and the set is being shut down for safety reasons, the "Fault" clears, the faulty bit(s) cool down, and the fault clears somewhat, and then it will work again, until,once again the part(s) heat up, and Fault, this in turn is "Sensed" and the unit is again shut down.
It is being shut down to avoid a fire and explosion or both. as related the protection circuitry is detecting that there is a potentially serious problem with the unit and it must be shut down immediately.
Now as to what the "Cause" is, well this is pretty impossible to actually tell, with just these symptoms, and until the set is examined and tested, a diagnosis will be difficult to say the least, it really must be examined to tell.
The very best thing you can do, is to get a referral to an authorised service center, contact a local or head office of Hitachi,and ask for a referral to a repair center.Now when in touch here, ONLY ask for a "Quote"as to costings, and type of repair etc. Now when you are made aware of this, you can then make up your mind as to what to do, repair or replace?

In my professional opinion, this most likely will NOT be a DIY, fix. One would need a service manual, and testing and repair equipment to even be able to begin to undertake this task. I know that the fastest and least expensive method of repair,if possible, is to engage a professional,and ask for a "Quote" and go from there. Also if one did insist on eventual DIY, then also the "Quote" would also isolate the area of the problem?

This is a very common problem and an easy fix. Goto www.TvRepairKits.com to get the parts and repair instructions.

You dont have to order one have a tech come and install one they should have plenty power cords laying around.

NO NEVER test a Diode under load. Any Diode that has THREE legs, is either a Dual Diode, OR a Power Diode. ALL, Diodes, usually measure 0.6 - 0.7 on the Diode test PN on a Multimeter. (The Multimeter supplies the current to test the junctions)
Are you sure they are Diodes, and Not transistors? NPN... PNP ? If they are transistors the you should measure Junctions, between the Base and Collector and Emitter. again, between 0.5 - 0.8 depending on type, a Go/No GO tester is NOT suitable to test semiconductors in a TV set, you need a Multimeter.
Before we can attempt to repair anything at all, is to get a service manual, and then there is one thing that one MUST do before anything else is done. Now that is, the making sure that the Power Supply,of the unit, no matter what it is, has the correct Voltages, coming into it, and more importantly, coming OUT of it. This is absolutely imperative, as, IF these Voltages are NOT correct then NOTHING will work, properly at all. So we must measure these voltages with a Volt Meter. All Voltage measurements are made with reference to ground. Meaning we clip, our Black, Minus, Lead onto the Earth, or Chassis, or Negative (-) "Rail" of the Power Supply. Now with the Red lead, we can now, measure these Voltages. Now sometimes, the Voltage of each Output is annotated,or written, onto the PCB, that will indicate the Voltage of that output. However most usually they are NOT, so in this case we MUST have a manual to tell us. Now this manual is called a "Service Manual" or sometimes a "Repair manual" This manual is absolutely vital so much so, that it can be near impossible to do without it. As apart from having "Troubleshooting" step through's, it also has our Voltages. When we measure these Voltages they are 100% EXACT, so IF the Voltage you measure, except for a few rare exceptions, the "Rail" that is NOT at the correct voltage is the one, that the "Fault/Cause" is "ON". Therefore we can now work outwards from the Power Supply, looking for the cause of that problem. Now if the Voltage is Lower than specified, we are invariably looking for a "Short", something has "Faulted" and is "Dragging" the Power Rail down to earth. Now if the "Rail" is "Higher" than the specified Voltage then the fault we are looking for is usually some sort of "Open Circuit" possibly a Diode, or resistor that has changed it's "Value". Now knowing this and knowing that the Power Supply is the FIRST place to start you troubleshooting and repair from. You now have a MUCH better chance of a "Fix". One thing more, DO NOT forget to get your SERVICE MANUAL. for you exact make & model. even if you pay for it, you will be glad you did.

Power board is dead,know how to solders?Replaced those capacitors that puff up or burst open.Or buy a whole refurbish power board at Shopjimmy.com,Ebay.com.

The problem is a blown capacitor and a pico fuse. You can get complete parts and instructiosn for this fix from TvRepairKits.com. They put together a kit for this. I used them for a convergence problem recently and they helped me fix my set.

That is a convergence problem. You can get complete parts and instructiosn for this fix from TvRepairKits.com. They put together a kit for this. I used them for a convergence problem recently and they helped me fix my set.
