Hi, this is a very common problem, I see this frequently at my shop. This is a switchmode power supply problem, and the set is shutting down, due to a fault, it shuts down, for safety reasons, to avoid a fire, and explosion or both. Please find these links for your User and two training service manuals for you. http://www.retrevo.com/support/Toshiba-57H82-TVs-manual/id/311ag811/t/2/
www.scribd.com/.../Hitachi-Training-Manual-Projection-Television-DLP-1 With this symptom, it is impossible to tell what the exact "Cause" of this symptom is. The SwitchMode PSU, is definitely involved, However, The LED's do not tell us what is wrong, sometimes it may indicate the "Area" in your case it is the X PSU, board. BUT thats NOT where the "Fault is" thats just the part that is affected. These days unlike the "Old" analogue days it just isn't realistically possible to fix anything but the most basic of problems with todays sophisticated units. This is quite apart from the Safety aspect, any unit that can cause a firs or have an explosion, or both, is NOT to be treated lightly, and and the repairer, of the unit is legally responsible, another thing to think about. Also, one must have tools, a Multimeter, a soldering iron, a deslodering iron, an oscilloscope, a signal tracer, tools, and most important of all, a Service Manual, without which, there is no way to even begin to understand and fix it, and more importantly Program it, AFTER it has been fixed. As these days a TV, is a PC, a Tuner, and an HDTV Monitor, and more, all in one. in the "old" days TV"s were more, rudimentary, and built to last for 20 years, and a "Parts" supply was set aside. They usually used to fail for only a few reasons, and they while still difficult, were less difficult to repair. Electrical knowledge was transferable, and they could be and would respond to, This-is-the-symptom-This-us-the-Fix, But that no longer applies, as now, it can be a Fault on I squared Bus, or "Sensor" failure, or it simple may have "Crashed" just like a PC, It could be a Diode go bad, and that will stop the whole thing. You see, in the day, the sets were Very "Fault Tolerant" because they were Analouge, and a faulty, component, or more sometimes, the set would always diplay something usually, and when they didn't it was one of anly a few things, sure there are always the horrid ones, and there are pleanty of those, but all in all it was quite easy. But with Digital Electronics, it either goes, or it doesnt, there are usualy few half measures. I mean thats the definition of logic either going or not. So it can take very little to completely paralyse a set, and generally give the only sysmptom, it can, by not working, usually No picture, or the like. So you, see the list is endless almost for any given SYMPTOM, as that is what is being seen, not the cause, as I keep going on about. Also any fault, usually involves the Power Supply, it is either the cause, the cause of the damage, or it is damaged. or ALL of them. Then after you have done the electronic repairs, you then must program the set to work, and align, and set up in general, any one of those settings missed or done wrong, back to square one. So, it is nearly always my professional opinion that one should always get a "Quote" form the manufacturers recommended service center, I cannot stress how important that last point is. It is even worth the cost of shipping. you see an authorised service agent, will have trained staff, trained on their brand, also they have first hand access to parts, original parts. This will actually save you money and ensure you can actually get it back fixed. Of course asking for a "Quote" also gives on the option of repair or replace. Often my clients,do not go through with repair, unless it is moderate, but in some of the more costly jobs they see it, as do i, that a replacement, with a warranty, is a better option. As an aside here, one could then tear the TV down, and sell the Known Good bits. You'd be surprised who needs parts, i myself often must by from third party sources to effect a repair. So money could be recouped, somewhat,and help out someone else. Anyway thats my 10c worth.

Hi


Thanks for using FixYa. Clicking sound can be from a bad capacitor on the power supply board. To start with open the back of the unit and check the power supply board for any blown capacitors. Also check the flyback as it can be some loose wires in the coil. Usually this happens when there is a vibration in the horizontal circuit, the flyback and/or coil can make this noise. Also inspect the fuse if they are working fine and please make sure to turn off and unplug the TV for at least 1 hour (this will drain off current from all components especially capacitors) before you perform any repairs. Opening the unit is only recommended if you have some electrical expertise. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

    As I said earlier that usually this happens when there is a vibration in the horizontal circuit, the flyback and/or coil can make this noise. To resolve this the flyback should be replaced and the horizontal circuit should be tested. Please do accept the solution if the issue is resolved or post a comment for further assistance.


    Thanks

    If the sound is coming from the power board then replacing it completely will avoid any further issues.

NO PICTURE, NO SOUND On My Plasma TV.


Should have been 3300 UF 10V caps that were bad? Shouls have been replaced with 3300UF 18V. 50V is huge. If it was replaced with a 50 the polarity may be wrong or the cap it too big to be seated property. Sometimes the caps just dry out and even a normal looking one will be the culprit of no OSD. Are you getting an LED fault code blinking? That should be a red led. Do you hear the relay clicking.? When you replaced the caps did you charge them? Just plugging in the set without trying to power it on for about 20-30 mins. I may be able to help you

Audio


This clearly is some kind of device configuration problem..Open control panel->sounds and audio devices->voice Now click on test hardware and tap on your microphone and see if the sound meter is showing changes..then click next and tap again and see if you are able to hear it in your speaker. If you cannot just download the latest device drivers for your sound card and that should fix the problem! Also you can download latest drivers for your webcam here http://drivers.softpedia.com/get/SCANNER-Digital-CAMERA-WEBCAM/LOGITECH/Logitech-QuickCam-Communicate-STX.shtml Try both of these and hopefully you will get it working!

No picture or sound


If you had a burning smell, well the board is toast. These sets are made to replace the entire board at one time. Before installing the replacement module, the picture tube should be checked. A defective picture tube ( such as a G1 short) may cause a failure in the power supply section.
