Hi Steve,

Thank you for giving me the pointers. The scopes are pretty old models (10years or more) and in India the tek representatives are not entertaining parts (old parts rather) enquiry also the calibration is due and I don't know whether they would do it or charge a hell to motivate me purchasing a new one. In my desperate attempt I bought another TDS210 from an auction is as is where is condition. When I received the unit I found that the LCD is defective. Rest okay. The mainboard, SMPS, Interface (All rotary encoders working). So ironically I got all the spares except the LCD. If any time you need something (other than the LCD) please do let me know.
