Check and replace the damaged component/s at its vertical scan output circuit. Replace all the electrolytic capacitors related with vertical scan output circuit. Replace all at one time. 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. Pull up older posts.

Desolder out the horizontal output transistor, and now power on the set. If the set now powers ON, replace the horizontal output transistor. It is faulty. [Collector to emitter or collector to base leak]

Sherwood stereo receiver RX-4109 Only the "B" speaker outputs work. When I plug speakers into the "A" output the do not work.


I believe that the "A" output stage has failed internally. Unless you're adventurous, it's probably more expensive to fix than it is to replace the whole unit. If you can be satisfied with only the "B" outputs, you're fine. If not, replace the receiver.

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.

JVC 27D201 picture gone except for one bright line across the middle, .5 cm. high


Hello
Vertical output section of your TV is faulty. There are mainly three resons for this fault. The first one is of faulty electrolytic capacitors at the vertical output section circuit. The second one is the vertical output IC. The third one is of loose solder termitals of components at the vertical output section. Resolder most of the solder terminals of this section by applying a little more solder, without making any solder bridge short in between adjecent solder terminals. If this does not help you, replace all electrolytic capacitors at the vertical output section circuit of your TV. There will be 6 0r 7 of them the most. Replace all of the at the same time. They won't cost more. If this does not hlep you, replace the vertical output IC. OK.

My china tv horezantal transister heatup


Hello
If horizontal output transistor heats up rapidly within seconds after the TV is switched on, surely there is some fault in the horizontal output section. It may be either with deflection yoke or horizontal output transformer. Deflection yoke fault is very rare, about 1% or so. but the horizontal output transformer fault is common. The winding in the horizontal output trnsformer, otherwise called as line output trnasformer [LOT] also. can be shorted inside it, and is irrepairable. It should be replaced with same type and number. Number and type is mor important, and should be insist on. Replace the horizontal output transformer. OK.

Hi My toshiba CX36H60 has a problem -- no picture but sound is good. what could be the issue and how to rectify it. Please suggest.


As sound output is ok, main board is correct with respect to sound output, video IF and ther stages. The fault lies on the horizontal output section. It may be LOT fault. Check it further for horizontal oscillator stage, and horizontal output stage. Check the collector voltage at the horizontal driver transistor. If you have a frequency meter, check the frequency of that point. It should be somewhere near 15625Hz. If the frequency there is Ok, then proceed to horizontal output stage. Check the horizontal output transistor. If it seems to be faulty, replace it with similar type and number. If the replaced horizontal output transistor heats abnormally within seconds after swich on the set, surely LOT has troubel. Replace it also with same model mumber and type.

No power whatever


Check voltage output of the power supply.
  1. If below the indicated voltage on the output terminals, replace the capacitors across the output terminals with the same specifications.
  2. If there's no voltage output at all and the fuse is intact, replace the 8-pin power regulator IC with same specifications.. It is usually DH321 IC.

dear friend:plse make sure that you replaced the output sensor and not the input speed sensor.the output speed sensor is the one closer to the fire wall,
