Fuzzy picture on SONY KP-61V90 - Sony KP-61V90 61" Rear Projection Television

SOURCE: sony projection tv model kp-61v90

possible power supply or short on the b+ run,check for shorted horiz. o/p tranistor.

SOURCE: i have a sony kp-61v90 projector tv and the colors

i'm assuming that your complaint is the red is predominant over the other colors- if it is a rear projection set, there are three tubes [r,b,g], and each one has its own flyback with a focus and 'g2' control on it. try backing down the red g2, and if the picture is too dark, turn down the color control [so you should have a black and white pic], then adjust the g2 controls until you have a satisfactory black and white pic- after that, when you turn the color back up, you should have a good pic. sometimes. adjusting the g2 can affect the focus, and there is a focus control on the flyback. there are also optical focus [moveable lenses] on each tube, but they are primarilly for initial setup of the set, and should never have to be adjusted, unless the tube has been replaced. fyi- i happen to have a complete set of sony rear projection tubes [r,b,g] complete with lenses and neck coils i am currently trying to sell, but it doesn't sound like you need tubes at this time, but it's something to keep in mind, because these tubes are becoming extremely rare and hard to find, and cost upwards of close to a thousand dollars a piece, i'm selling the complete set for four hundred dollars. good luck!

SOURCE: SONY KP-61V90 tv will not power on, red light in front,

Its 2 times blink error code that shows +B volt supply (+135 volts) is shorted, most probably horizontal output transistor is shorted, replace it.
If you are good in soldering parts in circuit board then take out horizontal transistor, check it, found shorted then replace it with same number.

Horizontal output Transistor Q502 number is 2SD2578 and available in Part Store for $10
Let me know for further query, if any.
Thanks.

Hello, It sounds like the deflection circuit is faulty. Usually,but not always caused by a problem with the switch mode power supply. It could be as simple as a capacitor or zener diode. Either way unless you are a technician I would get one to help you. Shouldnt cost any more than around $100-$180. As far as the pix goes,that sounds like the lamp they use to project images,around $400 fitted. Hope that helps.
