Another do it yourself fly-back tester assembled and working

Hi Humphrey,
Hope you are well today! I just wanted to inquire if you can get me i.c CD4015 over there because I have moved around various stores here in Dar es Salaam to find any but in vain.
If it’s available I can make arrangements for acquiring a few pieces.

Thanks! Regards,
Emmanuel-Tanzania

21 inch LG CRT television model 21FS6RG-T3 dead now repaired

I received a phone call from a client who wanted me to pass by his place to check on his TV which had a problem.

He told me he was referred to me by a gentleman who thought I can help him out of the problem, so I arranged a date and we meet at a specified location within my estate and off to his residence.

Upon arriving, the television which was already packed in the store was brought over to me and before opening I decided to apply power to see if there was any sign of life on the TV.

After applying power I got no symptom of power getting on and therefore decided to open the set…before opening the set the owner give me a disclaimer that the TV was from another technician.

Low output voltages from CRT monitor

Dear Sir,
I got CRT monitor. I have checked the voltages up to the big capacitors and everything is alright. When I check the voltages on the secondary side of the Transformer. I did not get good voltages.

I removed one leg of the diode and to check the voltage I heard a big sound in the neck board (one capacitor blown).

I don’t know why that happened. I am following your book which I have purchased online. Please help me. Do you want me send you some pictures of the board. This board is different from what you have shown in the book.
I will wait on your positive reply.

Best Regards,
M.Imran-India
