How can I find eht number for lg joymax 21d73 model

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

Check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/. It has schematics to many popullar brend TVs. Hopes it will help you find out the number of the EHT transformer.

There is a service manual available on this site but not sure what model it is. If you have a different one then happy to help look for it.http://www.scooterunderground.ca/knowledge/manuals/documents/SYM_RV250_Service_manual.pdf

If by eht you mean high voltage transformer, Google the model number with "parts" to see what is available or contact Philips.

My lg 47d7rb model tv , i have no 110v out put ,please help

If you have confirmed that the EHT has shorted the EHT must be removed out of the board if you need to find the replacement from a general electronic store as the EHT can be indetified . If you choose to order from LG, then all you need is to quote your TV's model number. Contact LG support center.
