Question about Sony KP-51HW40 51" Rear Projection Television

1 Answer

No Signal from cable setting.

When I turn on my tv,the cable will work for about two minutes. I can hear a click like a switch turning off,then the screen will go black and say No Signal. After that the screen will go fuzzy for a bit and then turn back to black and No Signal. I checked the Cable wire from the board to where you hook the cable in the back, and all connections are clean and tight.

    Its,actually a coax cable,sorry should have specified. I did recheck the coax with my old tv just to make sure that I had not damaged a connector and it worked fine.

Check settings on your source...make sure you are not plugging into a DVI/HDMI port on your TV unless you are in fact converting from DVI to HDMI (there a connector to buy) if thats not it replace the cable with a different one. There are several varities of HDMI cable and the signal is faster as you increase in price normally. I have Monster cables that work Perfectly....I would also check TV settings on the port you are plugging into and try a different one to see if the result is the same. If the result is the same you may have a bad source. Always rule out the cable too.

Some of the newer TV's dont turn on if there is no input signal. Try a DVD player and see if that works. If it does, then the issue is most likely with the cable jack on the TV, which may need to be replaced..

Hi.

The only non-obvious thing to check from user level point of view is the PAL/NTSC settings on TV and devices, but if the TV is in use on the country of purchase, and if you get the same problem using different devices, then this should not be the problem.


If the TV does not display any input, and you are sure that the source/input selector button on remote is working, then the TV has a fault signal board, that on this models should be integrated on the digital board. The TV in that case must be fixed by a technician.

Try connecting the DVD directly (bypassing cable box), using a SCART that you know is working. If you cannot see the DVD display after selecting EXT1 and EXT2 , then it is a faulty signal input on TV.

Ensure that the problem are not cables.

Try also the following:

  1. Disconnect TV power cord.
  2. Disconnect DVD power cord.
  3. Connect DVD using SCART on EXT1.
  4. Connect again power cords.
  5. Turn DVD on.
  6. Turn TV on two minutes after DVD is on.



If yous still cannot watch the DVD signal, then the TV is faulty.

Regards.

Lamp Light still on after replacement


First, A common mistake made is when you insert the orange ribbon cable from the Color Wheel into the DMD bd. To correctly insert the Ribbon Cable you need to look at both sides. You will see a shiny silver side and a dull black/orange side. You must insert the shiny silver side AWAY from the Color Wheel or towards the rear of the set. Now for the Ballast. When you power up the tv,Do you hear a short Buzzing sound? If you do that means that the Ballast is trying to fire up the Lamp and is working. Next, do you hear the Color Wheel spin up? If you do not then you have installed the Color Wheel incorrectly and you need to repeat the installation while making sure that you hold the rubber gasket in perfect place or else it won,t work. Chances are the gasket is in the wrong position and is binding the Glass Wheel. The Ballast is on the right side of the engine and on top of the Lamp Housing. You will see two RED High Voltage wires coming out of one end. Don't worry, there is no stored voltage in the ballast so you won't get a shock providing you have unplugged the tv from the outlet. That is the first step before you change any parts any way. Listen for the correct start sequence. With the rear backing off and the Safety Interlock Switch is being held in the up position, turn on the set. First sound you hear is a clicking which is the power on relay engageing. Then you will hear the fans turn on and then the Color Wheel spin up. Once the Color Wheel spins up and comes to full RPM then the Exciter on the Ballast will Buzz for less than half a second and then the Lamp should light up. Now if you have installed the correct Lamp and correctly installed the Color Wheel and you either are holding up the Interlock Switch or have reinstalled the rear cover and tightened all of the screws you should have a working tv.

Power turn off after 45 minutes to 1 hour used


Check the "Sleep Timer" settings. If set to 45 minutes then TV would automatically turn itself off 45 minutes from being turned on. The variance in the "on" times is due to the TV turning itself off after not getting a signal from the remote for fifteen minutes.

Good luck,

TC-32LX85 only stay on 5 minutes.


Just found a solution to this problem (conveniently hidden on unlucky page 13 of the user manual). This means that your TV is in store mode... it refreshes every so often and changes to the different inputs to show store viewers the quality of different inputs.

First, go to Menu - Setup - Advanced Setup and make sure that the "Auto power on" is set to "No." Turn the TV off and unplug it. Plug it back in. Press and HOLD the power button on the TV (not the remote). Hold for 2-3 seconds or so... you'll hear a few clicks. Release the button, then press it. The first thing that pops up should be, "Select viewing environment." Make sure you select "Home." Continue with setup from there.

Voila!

No picture, no sound, just chirping noise coming from back


NO - - signal did nothing to the set... Sounds like a shorted HOT (horizontal output transistor) and the feedback your hearing (chirp) is on the horz. transformer as it tries repeatedly to startup... Don't allow it to do that for too long...
