Why won't the sony plasma turn on while connected to cable box

The Akai is Samsung brand--have you when using that input that does not work gone into the menu and "selected" it and or highlighted it?

Your tv is a 2008 model, legacy 3d tv and requires a lot more than a current 3d HDTV does to view 3d. Today with a current 3d HDTV, Normally you only need a 3d source like a 3d Bluray movie and 3d glasses from Samsung and a HDMI cable connection from bluray player to HDTV. See below for your TV. You need a PC and IR emitter and Samsung 3d glasses plus user selected options on the tv.
Samsung 3-D Ready HDTV How do Samsung 3-D Ready HDTVs work?
Samsung 3-D Ready HDTVs are enabled by Digital Light Processing (DLP(R)) or Plasma Display Panel (PDP) engines that are capable of very fast refresh rates (120Hz). The inherent speed of these display technologies enables high quality stereoscopic 3-D by alternatively displaying left and right eye images. The display is synchronised with 3-D shutter glasses to provide the observer with a vivid perception of depth.
How do I connect my PC to a Samsung 3-D Ready HDTV?
The DVI output from the PC's graphics card must be connected to the TV's 3-D compatible HDMI port using a DVI-to-HDMI cable (or a HDMI cable plus a DVI to HDMI adaptor).
Alternatively, some newer graphics cards have a HDMI port instead of a DVI port. In this case, simply use a HDMI cable to connect the PC directly to the TV.
On all models, the 3-D compatible HDMI port is identified by the letters "DVI". (eg, "HDMI 3/DVI IN" or "HDMI 1/DVI IN")
What other equipment do I need to enjoy 3-D on my 3-D Ready HDTV?

• Windows PC with DVI output
• Compatible 3-D Shutter glasses and IR emitter with VESA compatible sync connector

How do I connect the IR emitter to the 3-D TV to support wireless 3-D shutter glasses?
The IR emitter should be connected to the "3D SYNC OUT" socket. The emitter should be placed on top of the TV with the LEDs facing towards the room. How do I turn the TV into 3-D mode?
Ensure that the TV source is set to "HDMI 3/DVI" (or "HDMI 1/DVI" for 720p models).
Plasma HDTVs Press the Tools button and select 3D Effect. Update from Off to Mode1.

Symptom:
TV shuts off unless all the input (phono and HDMI) cables are disconnected. The
symptom may be intermittent.
Cause:
There is an abnormal AC voltage entering the TV from one of the input cables or AC
outlet.
Remedy:
Follow the Testing procedure to determine if there is a problem external to the product.

Concept
Constant symptom
If the TV no longer shuts off when all input cables are disconnected, then one of the
input cables is introducing abnormal voltages into the TV. Panasonic Plasma TV sets
have 3 wire AC plugs.
As a result, abnormal voltages introduced into this TV will cause the TV to shut off for
protection.
Intermittent symptom
If the abnormal input voltage is borderline (marginal), the TV shut off symptom may be
intermittent. However the cause may still be detectable with a voltmeter.
Protection Proof:
Release the protect mode - the TV has to be unplugged to reset this protection circuit.

Threats from the HDMI input:
Excessive voltage from an HDMI cable connected product will activate the Plasma TV’s
protection circuitry. Placing an isolating / buffering connector (sometimes called a voltage
conditioner) between the TV and the HDMI input cable often solves the problem.
Testing -
Unplug all the HDMI inputs from the TV. Turn on the TV. Plug in the HDMI inputs one at a
time. The cable that causes the TV to enter the protection state is connected to the product
that has the excessive voltage (and signal). Avoid connecting this product until an isolating
connector is found.

Hi Ben,
Did you ever resolve? I have the same issue.

It souunds like te TV is having problems with the streaming data being applied Most plasmas with DVI connections were actually designed for PC type input signals  Unfortunately the TV's input may not be able to stand up to the stream of signal the DVD or cable box wants to display. You can try and lower the output of both devices to 720P Good luck to you

TRY BUYING AN 04 RECEIVER IT SHOULD WORK

I've got an E01 error on my Plasma TV . It's a Pioneer. There 's anyone who can help me? Tks ALX

In that case two things might be happening. 1. HDMI/DVI cable you using might be faulty you want to change that or 2. The HDMI input of your TV set might be the problem. I will suggest you use component cable instead, I am talking about the 5-color-coded (green, blue, red and red/wihte) cable to connect the set top box to your TV.

Here is the link to the user manual for the TV if you need it; http://www.haier.com/admin/en/product/upload/42EP24S-UM.pdf Check page 7 - The DVI input has next to it an audio input - DVI does not carry audio as HDMI does - you need to plug a seperate mono audio cable from your cable box to the TV at the DVI Audio input (top of page 12). The Audio needs to be in the one next to the DVI socket in order to work at the same time as the picture from the same "source" selection. Check page 18 "CATV Type" and make sure this is set to the correct one for your cable box Check page 21 that all the audio settings are logical and nothing is turned right down or muted. If none of this helps then please post back. What make and model is Your Cable box? Hope this helps :)

The monitor should have come with several cables and adapters. One adapter converts the stereo RCA plugs to a stereo 1/4 inch plug that connects next to the dvi outlet.
