Question about Sony KP-61V85 61" Rear Projection Television

1 Answer

I have a Sony color rear projector video projector KP-61V80 television, manufactured in October 1999. The TV screen went blank and while you can see that it is powered on, the timer/standby light is solid black. I've changed electrical outlets, tested outlets, unplugged, powered off overnight, and nothing seems to help or change. I've also tried to hard reset and hold the "power" button down for a minute to no avail. This happened yesterday evening and it was very warm outside. Could this have played any role in the malfunction? Any info you can provide is greatly appreciated. Sony seems to be stumped. Thanks, Jen

    Is there any sound? What do you see that makes you say that it is powered on? This unit has CRTs. While they usually have a blinking standby light if the power supply is ok you say that yours does not. Answer these questions and I can probably help solve your problem.

    Thanks for using FixYa.

    No, there is no actual sound or noise coming from the speakers however when the unit is unplugged from the wall, the timer/standby light is not lit. When I plug the unit into the wall, you can hear two brief clicks and the timer/standby light flashes once then turns solid red and does not change. No other noise or changes whatsoever until I unplug and plug in again. I assumed that with the that brief clicking noise and the light being solid red, the unit was powered on? But I have NO clue?!? BTW, what's a CRT? Thanks so much for your help! =)

    jngevas,

    Thanks for the extra information. CRTs are the conventional tubes used in TVs. Yours has 3. A red, green and blue CRT. They are run very hard to produce enough light to make a good picture. This generates alot of heat and will destroy the components sooner than a conventional direct view unit.

    From the additional information you supplied I would say that you have a bad high voltage section. This is very common with older TVs of any brand. The description of how your unit starts up is a classic symtom of a blown Horizontal Output Transistor due to a shorted or partially shorted flyback. If you do not know what CRTs are you are not going to be able to identify these components and replace them, but you probably can replace the entire board. These days boards are not that expensive.

    There are several ways you can approach this. I have a tip athttp://www.fixya.com/support/r4916851-di... which should walk you through the process and get your unit fixed.

    Thanks for using FixYa and for the great rating.

Tv went blank


Does the timer/stand-by light blink at all? If so, count how many times it does. It will usually be in intervals. If it isn't blinking, and you have nothing on the screen, you might have a problem with the "G" Board, part # A1316499A.
