Check the main power regulator section. Check all the resistors here. I assume this set to be an Indian one.

Onida 21''ctv picture coming in stamp type {cutting from four sides}


Hello
Replace its Horizontal output Transistor. If the base-emitter junction has a leak inside it, this type of fault will occur. Before replacing it, check the main DC voltage to LOT [Line Output Transformer]. It should come around 102VDC. If there is not this much voltage, check the electrolytic filter capacitor connected across thie supply line to main negative for open or value developed. Replace the same is good. Till there is low voltage found, check the retifier diode that rectifies this 102 volt DC. If all the above are OK and still you get a stamp like raster, check the heat of the Horizontal Output Transistor described above. if it overheats, LOT is defective and should be replaced with same type and number. OK.
