My Sony Trinitron CRT Model KV AZ-212 MB3 ( SONY 21" CRT WEGA)was for a few months been showing a 'pincushion' ") (" type of screen which I tended to ignore.
Unitil suddenly it got worse and fumes started to emerge out of it. I have now opened it. But, I was finding it difficult to access the PCB. The moment the back cover is removed the front started to be quite unstable. The CRT is so heavy that I had to lay the TV with the screen facing down. After this, I am stuck as I do not know how to access the PCB. Now, only the back of the PCB is seen with the CRT facing down. Also, I have noticed that a diode is burned.
My query is as follows:
1) How to disassemble the TV properly? Any Instructions step by step? 2) how to access and remove the PCB? 3) What are the likely problems? 4) And the likely solutions? Thanks.
