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. It should be somewhere near Hz. Popular Questions 6 Answers Green curved lines going across my t. Toshiba 36A50 36″ TV. The Television controller features a Z89C00 RISC processor core that 2sd202 the on-board peripheral functions and registers using the standard processor instruction set.
Not finding what you are looking for? Posted on Nov 07, You can’t post answers that contain an email address. The third main reason for 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 max point reward for answering a question is Please assign your manual to a product: Posted on Jan 02, If you have a frequency meter, check the frequency of that point. If the frequency there is Ok, then proceed to horizontal output stage. But the replacement in a Precision that has it is 2SD Hi Majid Just contact any service technician to repair your TV.

You just check these three datashset be sure about the fault. The winding in the horizontal output trnsformer, otherwise called as line output trnasformer [LOT] also.
It will be best for you. Replace it also with same model mumber and type. It should be replaced with same type and number. How can this be resolved. Here’s a link to this great service Good luck! Check the collector voltage at the horizontal driver transistor.
The HD74LS92 contains datssheet master-slave flip-flops and additional gating to provide a divide-by-six.
If LOT windings inside is short, hrozontal output transistor will get overheated, and will be get shorted soon. Login to post Please use English characters only. More Print this page Share this page.
As such, it is an extremely practical bus control IC. Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
TAK is power amplifier for driving a vertical deflection circuit of a small and medium screen size color Television. Overview In response to the demand for higher per for mance and productivity improvement for 2sr2102 processing Datashest 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.
Vertical output stage gets its working voltage from the horizontal output transformer. If the replaced horizontal output transistor heats abnormally within seconds after swich on the set, surely LOT has troubel. It may be either with deflection yoke or horizontal 22sd2102 transformer.

Check the 2zd2102 output transistor. From now on, this series will be deployed in series with Pin to Pin method a method to make another model without changing the pin arrangementDatazheet can correspond to the global chassis chassis that enables worldwide response only by replacing special parts. Your answer needs to include more details to help people. 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.
