Question about Sony KP-57WS510 57" Rear Projection HDTV

1 Answer

TV does not turn on

Hi Techman, We noticed a "sparky" sound coming every 5 minutes from back of the TV yesterday, and then today when we were watching a show the TV turned off. Now when we try to turn it on, the standby light blinks 7 times, there is no picture but sound is okay, then the TV turns off and the light blinks 3 more times. Looks like it is a common problem with Sony TVs, is it fixable do-it-yourself or do I need a Pro? Thanks Fixy

I noticed two days ago that the a/c cooling system was not cooling as it should. Drove it for a short time yesterday - same experience. Today after driving about 10 minutes in stop and go traffic -...


Sounds as if the electric fan on the radiator isn't coming on. Most radiator shops also work with A/C systems and may be more qualified to do the work. However, any good "normal" repair shop should also be able to diagnose the problem. Try not to drive it very far and keep close watch on the engine temperature. An overheat can do extensive (expensive) engine damage. If you have a fill cap on the radiator, fill it there (when cooled down) filling the recovery bottle may not be sufficient to get coolant into the engine.

No sound on older samsung tv


techs call this a cold or a bad solder connection on the output transistor most likely, tap on it here and there when it happens on the bottom and side of tv, if sound comes in then stops again then it would be a loose connection due to heat over time, if your inclined u can be fixed it, if bad chip it would play first then shut off, or if u have a cable box or rca outputs on tv use them on an amp to get sound, that would bypass amp output and u will use the preamp section which is a different circuit, debgh@comcast.net

Sony Plasma TV


I had this same exact issue yesterday. I own the same TV model and here is what SONY had me do to get the picture back. Ultimately the picture comes back, but it will be very dim and needs repair. Most likely a power supply issue. Try these steps:

-Press power off or leave with standby light on for 5 minutes (wait the full 5 minutes)
-Unplug TV / Press top buttons 5 times each to remove static from system boards (yes, each button 5 times each)
-Wait one full minute and plug TV in and press power on

The set you have has a bad tuner assembly. At this point most likely you would be better off getting a new TV set. Good Luck

Hitachi 51F500 (Two separate problems?)


My guess is that the sound you heard was that of some High Voltage discharges that could have fed back and damaged some semiconductors including the microprocessor itself. Since it could be a very expensive repair, I would be very tempted to look around for a new HDTV by JVC or Toshiba. Hitachi has slipped a notch or two in recent years according to my experience.
