Question about Hitachi Televison & Video
Tiny blue dots. first the were a couple now theirs over twelve. are these burn out pixels? the tv is a 62 V S 69A model. the tv is 2 yrs old. ron arnold
Yes this are burn out pixels.this pixels are either black or grey in colour when tv is in off condition.when the tv turns on the current passes through each pixel and that colour is shown on the screen ,of which colour light falls on the particular pixel.actually there is phosporous liquid in the screen area which gets lesser and lesser due to short circuit or power surge or by any of the component getting heated in the tv.this directly affects the pixel on the screen,.as the pixel starts burning the dots gets created.to clear this problem the main board of the tv needs replacement and the back of the screen the pixel needs to be cleaned.if under extended warranty get it doone by the company.other wise the reparing cost will atleast cost you $250 for this job to be done by a professional technician.this is not a do it yourself job ,so pleasde dont try to repair it manually.to clean pixels various machines are required to read the area of default.its a tough job as whole tv needs to be disassembled.
thanks. please do raTE THE solution.thank you for using fixya.keep updated.
