SOURCE: my onida 21" black color

Possible there is a fault in soldering. Poor joints in the CRT base circuit of the CRT tube will result in poor connection after some use due to the fact the heating and cooling will detach off the leads. So use a good soldering iron to touch up all the points in your main board and the CRT board and it must work provided your tube is not faulty.

SOURCE: i wish to know the input voltage given to Onida 32 Xaria board

Only the correct replacement board should be installed--another even if similar looking will not work.
