Something is probably bad inside. The switching sound is the power supply trying to power it up but can't.

Try to do it after a hard reset. Unplug the TV from AC mains wall socket, and re-plug it back after 10 minutes or so. This must make it a hard reset.

If not input or source button on the set you need the original remote.

Unless there is a source or input button on the set you need the original remote.

Since most passwords require a number sequence to be entered I doubt it can be done without the original remote and the correct code numbers.

Check its main power regulator section for any faulty capacitors.

Check the HDMI cable. Try an other cable.

I had a similar problem with my 42 in Philips LCD HDTV.

Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.

Here are some options for you.

1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

Remember, TVs CONTAIN HIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk.

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found online. I would definitely shop around though.

3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.

This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.

Hope this helps and if it does please rate it accordingly. Good luck.

The HDMI[1] input on your TV receives digital audio

and uncompressed digital video and audio from an

HDMI device or uncompressed digital video from a

DVI[2] device.

This input is designed to accept HDCP[3] program

material in digital form from EIA/CEA-861/861B-

compliant[4] consumer electronic devices (such as a settop

box or DVD player with HDMI or DVI output).

The HDMI input is designed for best performance

with 1080i high-definition video signals, but will also
accept and display 480i, 480p, and 720p signals.

To connect an HDMI device, you will need:

• one HDMI cable (type A connector)

For proper operation, it is recommended that you use

a short HDMI cable. You should not encounter

difficulty if you use an HDMI cable shorter than 16.4

ft (5m).

HDMI cable transfers both video and audio.

Separate analog audio cables are not required (see

illustration below). Some CDVs (video CDs) may

not output digital audio signals. In that case, you

may hear sound by connecting analog audio cables.

However, if you connect analog audio cables with

this connection, the HDMI terminal on the TV will

not receive the HDMI digital audio signal and you
will hear analog audio only.

To ensure that the HDMI or DVI device is reset

properly, it is recommended that you follow

these procedures:

• When turning on your electronic components,

turn on the TV first, and then the HDMI or

DVI device.

• When turning off your electronic components,

turn off the HDMI or DVI device first, and
then the TV.

To connect a DVI device, you will need:

• one HDMI-to-DVI adapter cable

(HDMI type A connector)

For proper operation, the length of an HDMI-to-

DVI adapter cable should not exceed 9.8 ft (3m).

The recommended length is 6.6 ft (2m).
• one pair of standard analog audio cables

mine does this same thing and in the manual it says that this is an indication that the bulb is about to need replacement. I did this and still the same issue. The only small solution I have found is to disconnect power and try to turn it on until it finally does. I am searching for a REAL solution though.

Toshiba 30HF84... | Answered on Feb 25, 2010

I have a Panasonic with a defective audio output, and found a cheap alternative to an impossible to repair problem.

Mine still had audio if I connected headphones to it, but the speakers would get nothing. I found that a decent set of computer speakers (with sub woofer) worked great, and I could move the speakers to provide awesome stereo. Sub woofer is behind the TV.

I did a quick look and did not see an audio specific board available. Likely, it's part of the main board and not cheap to replace.

I hope you can use my fix. It's actually a better sound now than original.

check your connections properly there could be some thing that you are not connecting .or your cable are not compatible.good luck

Things are not so simple. Your universal remote control may not be compatible. Use code search to find out. All URCs do not contain all possible codes for all devices.

Use code search.

The TV's main culprits to be causing this problem are "dynamic contrast" which maybe darkening the backl light in dark scenes an example a night time or a dark scene in a movie. To make the blacks be deeper (as LCD/LED TV are rubbish at blacks) or brighten it on bright scenes to make the light be lighter and once again to make the blacks be deeper so the images pop out. Also "eco lighting" this will dim or brighten the image based on the amount of light in a room in order to be saving energy. Ether way the easy fix is to turn both of these features off. You will get rid of the problem and enjoy more subtler shades of colour that would otherwise be bleached (brightend) or crushed(darkend) out..

Try this. It might work or it might not

1. Open the tray
2. press the following sequence using the number keys: 98790 (this is equivalent to the code 9879 with the zero at the end representing all regions)
3. Press Close Tray - there should be a sign on the TV screen saying something like 'Region set to 0'
4. Turn off the DVD player for 5 seconds
5. Turn on the DVD player.
