Great and quick support. The maual was exactly what I was looking for and my problem
solved. Many thanks.
;
Very good service Within one day i received a pdf of the users manual and electric circuits so I was able to measure the different voltages in the printed circuit and find out the fault Payment was also reliable and easy.Without the manual i could not have repaired.So thanks to "Search for a manual"
 ;
you are doing great job guys.....my father ask me to find out the schematics of Sony KV25R1D to sort out the problem ..(he was electrical technician, and excperianced with TV and simillar stuff). finally he found the cause and change all necessary parts....now he has got working old dog..and is very happy!!... thank you all.. NB..he also saved the repair cost.

Perfect. Received my manual within 24 hours. Clear scan of the manual I needed. No problem.

Item as described, very well detailed manual with complete schematics. I've received the download information shortly after payment, very good support.
