CS21B501HL THIS MODEL EHT NUMBER - - T - Televison & Video

The EHT number for a Philips TV model 21PT3525/V7 can vary depending on the specific version of the TV. However, the EHT number for this model is typically BSC25-0235 or BSC25-0217.
It's important to note that replacing the EHT can be a dangerous process, as it involves working with high voltage components. If you're not experienced with electronics repair, it's recommended to seek assistance from a qualified technician who can perform the repair safely and properly.

Even if you have the part number I'd be surprised if parts would be available for a CRT TV

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 for picture to appear ( 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 ........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.......
