Hint for audio OK,No video problem

Most of the time in TV servicing TV s come with audio OK,No video problem.
My kind suggestion is before going into trouble shooting video and H-out section, slightly increase screen control of LOT. Due to vertical failure some time it will be h-line. Due to less screen that H-line will be invisible.
If it is H line trouble shoot vertical section else as usual.

L G T. V a strange problem(exclusive in e-care blog)


There was an LG TV came for repair. The problem was the TV gets switched on initially runs for
10-15 mins then suddenly comes to stand by position.
Initially as usual I thought it was a dry dry solder. I thoroughly checked for dry solder. but the soldering on the board was also almost OK. I touched up all the crucial soldering points for safer side. Then I swished on TV , after 10 mins it came to stand by position.
Then I checked out with my senior who have a 25 years of electronic exp. He told in LG tv this type of problem occured before to him also . The cure is nothing but replacing LDT(line driver transformer).
Then I did the same. I replaced LDT .
TV is working fine now.
In e-care service centre we repair 4-5 TVs average a day. other than that many nos of other electronic devices. Sharing all the experience gives a happiness.But time doesn't permit.
Any way next time when u come across same problem with LG tv. Just replace LDT. and say thanks to my seniour frnd.

About waste e-books

I have seen many websites selling e-books related to electronic troubleshooting.
Even to test the contents I have purchased 2 e-books also. Then I got shocked compared to
the hype given to the e-book the contents of the e-book was nothing.
So please think before purchasing such kind of e-books.
When there is huge information is available on almost all the topics why to waste money on that.
And also I want to tel you another thing one good multi-meter itself is enough to trouble shoot all the problems of electronic devices according to my 8 years of experience.
so don't get tempted to buy waste e-books and self designed tools.
Even I have recieved threatening e-mails when I declared to publish free e-book.
They thought I may disturb their business.
Any way I am free of many busy schedule now....
You can expect more postings in this blog...
Thanks and regards
