Question about Sharp LC32D47UT 32 in TV

Open Question

TV turns on for brief moment, then shuts off.

TV turns on like normal, it presents the channel the tv is currently on, you can hear the volume kick in, but in a matter of a couple seconds the TV shuts off leaving the power button blinking green. When I hold the power button down for a while I get the light to turn yellow, then red, then completely off again. I've tried anything I can think of to somehow reset the TV, but nothing has worked.

Did you check the service manual troubleshooting guide yet. You can try disconnecting the power to the inverter board and see if it will stay on and have sound.

You may also have one or more bulbs out. Mine had three out, which makes the inverted detect a fault and triggers shutdown. I painstakingly adapted the clips from the old bulbs onto ones from another 37" tv. I hear that you can buy them for $13 each. I am not sure where though. I just bought a 'cracked-screen' 37" on Craigslist for $30 and retrofitted the lamps.

You have to turn up the volume to 38+ in order to hear the TV, when you use to be able to hear it at 10, is there a control board that goes out and what Is the name of it?


Hi Geoff, I hope I can help you with this. If you are using an accessory device (DVD, DVR) check cables to see that they are secure and if device has audio out option that it is set correctly. Also check to see that Video and Audio cables are connected to matching inputs on your set.
If you are using DVI to HDMI you will need to use a separate digital audio cable. DVI cables do not carry audio signal. After attaching the audio cable if you still do not hear sound you may need to set Digital Audio In. To do so:
  1. Press Menu Button on remote.
  2. Press the cursor ring down to highlight SETUP.
  3. Press the cursor ring left to enter SETUP menu.
  4. Press the cursor ring down to highlight SOURCE.
  5. Press the cursor ring left to enter SOURCE menu.
  6. Press the cursor ring down to highlight DIGITAL AUDIO IN.
  7. Press the cursor ring down to select the source you want to associate Digital Audio with. HDMI 1 or HDMI 2 in this case. You might need a software update also.
    The latest software solves the issues below:
    1. TV (Plasma 42" and 50") will not turn ON/shut off itself and Red LED blinks 4- times. Recover if main switch on/off.
    2. 37" LCD full white screen appear when upgrade software.
    3. Some channels not available after turn ON.
    4. Delta volume changes, not remembered.
    5. Preferred channel changes, not remembered.
    6. Green or yellow static (sometime snowy) on HDMI picture.
    7. Picture and sound loss for 5 to 10 sec (green LED is still ON) and back to normal.
    8. Audio loss in all inputs and can be recovered when main switch ON and OFF.
    9. TV set turn ON by itself/ green LED light up and goes off when set is ON.
    10. Intermittent audio loss in NTSC RF channel.
    11. Crack sound with high input signal.
    12. Include the possibility to download the rating table (RRT5 capability) for digital programs.
    13. No video/ no picture with sound.
    14. Intermittent On-Screen Menu pop up by itself and can be removed by pressing the 'MENU' button.
    15. Channel information display too long.
    16. Improvement on scramble channel.
    How to check the current software version on my TV set?
    1. Press 'MENU' button on remote control to display the on-screen menu.
    2. Select TV MENU and press the cursor right.
    3. Select INSTALLATION and press the cursor right.
    4. Select SOFTWARE UPGRADE and press cursor right.
    5. Select CURRENT SOFTWARE INFO to display the current software version on your TV set.
    6. If the TV software version is lower than the version posted on the website means your TV set needs to be upgraded.
    7. Follow the instruction in the user manual or Firmware Upgrade Readme file on how to upgrade your software.
    Where can I find the latest software for my TV set?
    The Firmware Upgrade Software and Readme File documents can be found on the Philips support website. Refer to the SOFTWARE section.

It coming on and after a couple of seconds cut off


Without a brand AND model number or a better description of the problem, any suggestions would be nothing more than a guess.

Unless you are prepared to repair the TV yourself, professionally performed repair, even simplest ones, will probably exceed the cost of a new LCD replacement set.

Due to X-ray and other safety concerns (equipment and/or people), CRT TVs constantly check the voltages and signals required to make a CRT work. A few seconds grace is allowed during start up but after that, any excessive high voltage (real or imagined) or loss of beam deflection circuits will cause the TV to turn off.

Please do the following:
1. Move the TV to a quiet and preferable totally dark room.
Wait until night if necessary.

2. Stand within an inch or closer to the TV screen.

3. Turn on the TV and look and listen for the following:

a. Whoosh sound and/or head hair attracted toward TV screen
Yes. High voltage activated and charged CRT screen.
No. High voltage failed to activate.

b. Hissing or normal sounds from the speaker(s) while set is on.
Low voltage circuits probably okay. Defective low voltage regulator can cause high voltage to exceed limits.

c. Entire screen briefly lit up or single bright spot at center of TV screen

High voltage worked for a moment then the TV shut off due to over voltage or current problems.

d. Brief bright line from top to bottom or single bright dot on TV screen

horizontal deflection circuits bad
vertical deflection circuits ok
TV shut off due to bad deflection/sweep circuit

e. Brief bright line from left to right on TV screen

horizontal deflection circuits bad
vertical deflection circuits ok
TV shut off due to bad deflection/sweep circuit

It would be helpful for you to perform the above "up close and personal turn the TV on test" and report what happened.

What outlets do I hook up to on the reciever and the tv for it to play on regular tv stations


Cable Box optical Digital Audio to Coby Digital Audio In. (This brings TV-related multi-channel and normal audio into the Coby so you can hear it over the speakers. Turn TV volume OFF.

The cable box probably has a pair of stereo Audio Out RCA jacks. Run those directly to the TV so you can watch and hear cable programming over the TV's speakers without having to turn the Coby on. Turn TV volume UP.

Depending on your TV's Video In capabilities, use the Cable Box Component (Red, Blue and Green), or Composite Video (single Yellow associated with the Audio Out) directly attached to the TV.
