Noise in sony tv

SOUNDS LIKE A FAULTY RELAY HAD THIS FAULT PREVIOUSLY ON SAMSUNG -SONY-TOSHIBA

Typical failure for all plasma tv's is a blown Y-sustain board. Another high failure for all tv's is dried out bulging capacitors in any of the power boards. You likely have one of these problems.

Sounds like power supply is failing

That model is an LCD that uses a backlight. Probably with CCFL tubes. They are known to have bad inverter supplies. Its an old TV though. Keep that in mind.

I have the same problem with my TV. I haven't verified this yet, but someone I know who's a electronics genius told me that its the buttons on the TV (power, channel, volume, etc.) He said at the factory many of the "button boards" were tightened too much and cracked. When you turn the TV on, the clicking noise is a loose connection. He said it's easy to replace yourself, and about 30 bucks on ebay. No promises though.

I haven't worked on an RCA DLP but have on Samsung DLP, based on your description it sounds like the color wheel is bad. Take the back off and turn on TV make sure its not a fan making the noise ,but most likely its the "wheel" it is inside the light engine probably right next to where the lamp is plugged in. If the whine comes from this area definitely the wheel.

i hear a clicking noise- the clicking noise is most likely you ballast trying to power the lamp, but failing. this may indicate a defective ballast if you have recenty purchased a new lamp.I recomend you have your lamp tested to help narrow down the cause of the defect. It's highly unlikely for a new lamp to be dead on arrival

This is a fault definately. I have run into this with Samsung plasma tv's and find if you do some electrical adjustments you can usually remedy the situation. Sometimes though, it is the panel going bad or a board. Do u have any pictures i can see? Also keep in mind that if you have a DVM you can make the adjustments yourself. Good luck...GURU JAY

ysus pcb that supplies voltage to the panel is faulty

Ke series makes that an early plasma TV

that old will probably be throw away or requires the replacement of the whole printed circuit of the TV
or power source

if chinese built that circuity may no longer be available

any local mobile TV repairer can check that TV out for you
