hi,
Your tv has problem with the base board. you can see the base board on the picture tube neck. To see the base board you have to
open your tv. The problem is dry soldering of
component in the base board. To rectify the same you need soldering iron. Just check the base board carefully for any dry
soldering of
component leads. (dry soldering means loose contact or bad
contact of
component lead in the soldering side of the base board can happen after years of use.). Just find out the
point which is dry.
resolder the
point using the
soldering iron.
that's all. then test the tv it will be ok.
If you can't
find out the exact location just
resolder all the points in the base board. it will take some time to do it . just
take your on time and carefully do the same. If you nee any more assistance feel free to contact me through
fixya.
Below i have added a picture , how the dry soldering looks like. The points inside the yellow circle
ok
