after 4 or 5 yrs EHT ( transformer that supplies voltage to CRT TUBE - TV TUBE ) becomes weak - then 1 of the indication is that it takes few seconds time to start ( after few days it takes few hrs & then stops completely).............. .......so solution is EHT ( also called as flyback transformer ) should be replaced....... {{ few details about EHT---- its size will be around 3inch X 2inch X 2inch ---it will have 2 or 3 knobs to adjust focus , brightness ------ at bottom around 10 pins will be there ------- from EHT 1 thick red colour cable goes to CRT TUBE --------- on EHT its part number will be there }} -------- so if user is a technical person having idea about components ( resistors, transistors, diodes, etc ) , having tools like multimeter ( to check components) , soldering iron, soldering lead, flux, desoldering wig ( for removing components), etc also little experience in servicing field( compulsory) ----------------- then user can remove EHT from main board ---- take to electronic shop ----- buy same type EHT --------- fix to mainboard ( knobs on EHT should be adjusted according to picture --- after switching TV --- this adjustment is very important ) ----------iam from bangalore ----- here EHT's price will be around Rs 250 ( US $ 6 ) & for my customers (in bangalore) i will take another Rs 500 (US $ 11) as service charge......i don't have any idea about EHT ' s price & service charge in your place.........since it is very risky job i suggest to contact TV service engineer ------- because they are highly experienced & can fix this component very easily. ------------ [[ sometimes along with EHT another component called transistor ( big in size - situated close to EHT - it will have 3pins - its size will be 1inch X 1/2 inch X 1/2 cm --approximately ---- black in colour ----- fixed to aluminium metal ) --- will also gets deffective --- so this component also should be checked ]] ---- in your case this transistor is good ... because when this component gets deffective then TV won't get '' ON '' .............so in your case only EHT should be replaced.........100% it works normally .....GUARANTEE.......

Hello,

To use 'Onida' mobile as a modem to access internet in your computer you need a software called 'PC Suite'.
Mobiles like 'Nokia, samsung, LG, Blackberry etc.. pc suite we can download it from internet searching with the model number.
But 'Onida' is not providing their pc suite to download,
For that you can to contact the shop where you purchased the mobile or you can get it from the near by service center.
Once you get this pc suite (suitable for your mobile) you can install it on your computer and get a gprs prepaid card ( Rs-15, Rs-50 etc) scratch and charge it to your mobile.
Now you can easily browse internet.
