Hi Folks,
I have a Sony KV-x2552U which has developed a problem and won't switch
on. When the power switch is depressed there is a loud thump but no
picture. When switching the unit off there is a flash of colour as it
does so.
I do not have any knowledge of tv repair but do have a brother who is
into electronics who could solder etc safely and do the repair for me.
What I need to know if anyone has any experience out there is:

a. is this a common or simple to repair fault or should I just scrap
the unit?

b. If repairable any instructions would be useful.

nb. I do have the schematic diagram of the chassis

Cheers

You do not have enough details to even have a clue to what is going on.
The powersupply outputs must be verified. There must also be
verification if the scan generator is putting out, and that there are
the proper supply voltages to the horiz output stage. This is only the
beginning. You will need the proper tools, and some test instruments to
work on the set.

It would be very difficult to troubleshoot the set over emails.

If you or your brother are not experienced at TV servicing, it would be
better for you to give the set out to a repair centre to have it
properly serviced. There are also some very serious safety issues that
must be regarded with servicing TV sets.
