The fan stopped charging,the indicator light fails to lit when it is plugged to an electric socket.I discovered that the rechargeable fan make use of a transformer and rectifier as power source and the transformer is burnt.Replaced the burnt ttransformer with same volt rating and it starts working again.

thereafter I checked the ysus board and detect 2 faulty 2.2ohms resistors.In troubleshooting when such resistors break down it is adviseable you check the board further for faults that may have resulted in the breakdown of these resistors.I detect a shorted mosfet and diode on the ysus board. Fortunately for me I have the same board in my workshop so I did not bother myself repairing it,I just replaced it and it worked perfectly.Hope to find time this week to repair the faulty ysus board.

A lcd tv(32") was brought in for repair at my workshop.The maker is
'acoustic solution',I don't know they are into lcd because I had
repair their dvd products very well.The fault is that when it is power
on,a black bar is at middle of the screen and it extends to the bottom
of it.On opening the cover,i saw two capacitors (15uf 450v)close to
the inverting transformers,one of it is bulged while the other looks
fine.Ranging my digital multimeter to esr i detect both capacitors are
faulty so i changed them with same value.when the lcd was powered the
fault was gone.

Atimes,people ask reason why we repairers(myself inclusive) always
have a lot of junks set in our workshops .Well,there are some
components that are not available in the market and you can only find
them on panels that are junks.Components on them are more better than
those that are sold in the market.These junks are also useful for
comparison purposes in a case where you have a burnt component,its
value can be known from junk of similar panel.when there seems to be
nothing useful on the panel that is when it is disposed.

It is very important one gets conversant with series of tv panels as this help in correcting some faults most es pecially those brought in for repair but have been taken earlier to a repairer.A customer referred to my workshop brought the tv with a complain that the standby lits only but it fails to start.On checking it,I detect the HOT is faulty and replaced with a new one but alas the problem persist.All the components surrounding the fbt were perfect according to my meter reading.Then I went straight to the eeprom 24co8 and changing it corrects the fault.The tv starts quite alright but I observed that the display wasn't okay and this is because the HOT heats up and becomes very hot.I changed the fbt but still it continues to heat up.At this point I now remember that I have a similiar panel from where I discovered that the value of HOT used by the former repairer was the wrong one and has misled me also.He uses bu808d instead of bu2508af, the readings of these transistors is obviously different and the tv works well as I replace with the bu2508af.

It is very important for a repairer to be very observant because many atimes the major causes of failure in most of electronics board is dry solder joints.Before and after repairing a board,I will advise you check it very well to make sure all dry joints are resoldered and avoid hurriedly assembling the set as this may give you another problem thereby compounding your work.A good repairer must have a good eye.
