If the replaced horizontal output transistor heats abnormally within seconds after swich on the set, surely LOT has troubel. The email address entered is already associated to an account. It should be around It should be replaced with same type and number. It was working beautifully but just stopped. The Television controller features a Z89C00 RISC processor core that controls the on-board peripheral functions and registers using the standard processor instruction set.
Tell us some more! The HD74LS92 contains four master-slave flip-flops and additional gating to provide a divide-by-six. Overview In response to the demand for higher per for mance and productivity improvement for signal processing LSIs from the color Television market, We developed a signal processing LSI LA with built-in microcomputer for color Television based on in one package concept.
TAK is power amplifier for driving a vertical deflection circuit of a small and medium screen size color Television. The max point reward for answering a question is Vertical output stage gets its working voltage from the horizontal output transformer.
Please enter a valid email address. If there is winding short in the Deflection yoke, even a sinlgle winding gets shorted, it puts a great load on LOT, which in turn effect horizontal output transistor. Instant Repair Help over the Phone 6ya. Check it further for horizontal oscillator stage, and horizontal output stage. The fault lies on the horizontal output section. Number and type is mor important, and should be insist on.
As sound 2d is ok, main board is correct with respect to sound output, video IF and ther stages. Helpful 0 Not Helpful Flag. If the frequency there is Ok, then proceed to horizontal output stage. If there is no frequency, the horizontal osciallator jungle IC should be suspected. Please assign your manual to a product: It should be somewhere near Hz. In addition to providing IIC bus control based rationalization of IC control and the adjustment manufacturing process associated with the TV tube itself, it also includes all functions actually required in mass-produced Television sets.
Lately during the filling cycle water hammer is occurring. The third main reason 2xd horizontal output transistor failure is due to an open or dry solder at the capacitor connected to its collector to negative It will be usually pf to pf, according to the TVs screen size. The winding in the horizontal output trnsformer, otherwise called as line output trnasformer [LOT] also.
How can this be resolved. TOP Related Articles.
