My olevia tv sparked immediately I put it on ,and refuse to turn on.


Sounds like LOT arcing. Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here.

Dc shut down


Check the LOT [Line Output Transformer] and [HOT], Horizontal Output Trnasistor for fault. In most cases, collector to Emitter junction of the horizontal output trnasistor found faulty. Replace it first. If it do not help you, replace the Line Output Transformer.

TV COMES ON BUT GOES BACK OFF


Line output transformer ro Line output transistor to your tV is faulty. Just replace the Line putput transistor first. If it do not help you, replace Line output transformer {LOT}.

Where is the flybac located in a rca hd52w59


Hello
Flyback transformer other wise called Line output transformer {LOT} is actually a step up transformer, which supplies extra high tension voltages to the guns. It can be locatee on the main printed circuit board. 2_7_2012_5_19_59_pm.jpgJust see the different views of the main board of your RCA TV. You can see the flyback transformer at the left top corner, look like a large black componen; with a ferrite "U" type core goes though it. It is the LOT. Line Output Transformer, otheriwse called as Flyback Transofrmer. OK.

I need a transformer


Hello
It is not clear from your post, that which transformer part number you wants to know. Anyway I'm hereby send you the part numbers of it two main transformers.
[1] Horizontal Ouput Transformer, or Line Output Transformer or Flyback transformer [HOT or LOT or FBT]; Part number is (257807)
[2] Switeched Mode Power Supply transofrmer [ SMPS transformer]: Part number is (257807)
OK.

Power ok but not eht function


Hello

If you have tested the secondary section of the SMPS power supply of your Sony TV, amd found it OK I thinks, and posts this solution.

If the secondary supply rail 125VDC is found ok, just goto to the Horizontal Output Transformer, a small transformer diretly soldered on tho the main board, very near to the Line Output Transformer [LOT], and its secondary winding is connected to the base of the line output transistor, which in turn drives the LOT said above, generates EHT you described.
The base of the line output transitor must get appropriate frequency to switch on and off. This frequenct is gerally comes to 15625Hz. Just measure the voltage across the primary winding of the above said line driver transformer, which can be a possiblity open winding. Check the voltage at the collector point of the line drive transitor connected ti the one end of the primary winding is easy. Then check the voltage at the other end of that winding. There must be a little difference of 2VDC or so, if the line drive section is working, and fault is after that section, that is line output section. If you have a digital multimeter capable of measuring frequency, measure the frequency of the collector point of line drive transtor, and find out whether there is 15625Hz or near to this frequency comming out. Never touch the multimeter prob to the collector of Horizontal Outout Transistor, while it is working. Your meter will get damaged.
Line output section, contains tha LOT said above and line output transitor. If the Line Output Transistor has some sort of leak, normally collector to base leak, it will not drive the LOT to produce EHT and it wlii heat up also.
Just check it heat effect, after switching the set on for a short period of time, say 30 seconds ro so. If it heats up abnormally, suspect the line output transistor and LOT. You just replace the line output transistor first, with same type and number. If it doesn't retify your problem, LOT said abve is faulty, and it also should be replaced with same type and number.
If you have to replace the horizontal output transistor, and the LOT said abve, insist on orginal, and not replace it with a susbstityution, as these are critical components in all TVs..
If you need further assistance, get me through Fixya, and be free to conact me. Ok

Low Voltage Output Transformer, is a very common term for this abreviation LOT. I have also heard it referred to Line Output Transistor, or Line Output Tranformer, and a vew others.
