Your television hdmi ports are no longer working. You could try to solder new ports onto the board, or you could take it to a specialist in television repair.

SOURCE: Dead Mitsubishi VS-5006R.

The most common problem with this set in the start up circuit of the power supply. There is a resistor, a 270k, R903, and even if it checks or looks good replace C920. Also there are small resistors off the flyback transformer that will open up because of bad capacitors feeding those circuits. Also any capacitor that has a swollen top or body, replace. Double check and make sure the B+ fuse is not blown. If it is, before you replace it, check to see if the horizontal output transistor is shorted. If it is, replace the transistor, BUT intall a 100 watt light bulb across the blown fuse. If , when you turn on the TV set, the light bulb glows bright, one of the deflection yolks is probably shorted. Unplug the set, and pull out one of the yolk plugs. tun back on the set. If the light now glows dim you have the bad yolk. If it does not and is atill bright, unplug the set, replug in the yolk, and take another yolk plug out. Do in this order and replug back in the tested yolk and make sure you unplug the set each time you do this or you will cause more problems. goos Luck. Please do not forget to rate this thread.

There is a resistor by the high voltage transformer,it has low value and it opens for no reason,he is likely open and does not let the set stay on,if you are familiar with tv service you can replace it and while you are down there check for any over heated areas and resolder them specially the convergence IC.This resistor is located in the back edge of the chassis in the board in the right side and it might be hidden by a plastic casing that covers the high voltage transformer.If you are not too familiar with tv service you should seek the help of a servicer.Let Us know how it goes or if you need more information.

The port is called a DVI input. You can find a HDMI to DVI adapter at Circuit City, Best Buy, Ultimate etc..........

Does the TLA-04011C Polaroid Television support a ROKU streaming device? I've hooked everything up and the HDMI7 port is set to 480dp, how do I change this in order to setup my ROKU?


Ive never heard of a set having 7 HDMI inputs...go to HDMI 1 and use that for your Roku device and all should work fine, nothing to adjust or set other than select the HDMI one input

Just hooked up the streaming stick to HDMI to the TV. nothing is showing up, What do I do now?


Sounds like you have a bad connection on either your roku stick or your HDMI PORT.Does you ROKU stick show a white light if not check power cable or electrical plug.
Try wiggling ROKU stick just a hair or push it in and out until you get a signal..A purple screen with the words ROKU should show up on TV.If you have a bad port on TV it would have to be replaced but this is rare,if you have a second port on tv try that.Have you tried your ROKU stick on another tv?Does your streaming stick go in vertically or horizontally,if it goes in vertically it may be pressing against side of tv prohibiting a good connection.You could try a HDMI cable, plug the HDMI cable into tv and put ROKU in other side of cable.There is also a restart button on ROKU stick push it and it will start blinking,if it doesn't light up you may have a defective ROKU stick.

I have a 2009 Lg 37lh30 Tv and for the most part it works until recently. I am now getting a HDCP rejection when using an Apple tv or Roku and no screen when using my bluRay Player (which use to work


Some TV's & cables are not HDCP compliant . Sometimes you can replace the cable to fix the problem & other times you have to replace the tv because its not HDCP compliant . First check to see if your tv is HDCP compliant .

Out of no where my Vizio won't show cable, Blue Ray, or shows on Roku. One of the HDMI ports hasn't worked well for awhile so would have to switch HDMI ports to watch Roku or Blue Ray, but overall worked...


you may need to change the HDMI board in the tv. it will be the hole board the parts are just to small to replace them all to get the HDMI board working again. find a second hand replacement. should be fine with another known working one.

Can someone please help me get my laptop working through HDMI cable onto TV on a sony VAIO VGN-FW23G. I need to know the process to do this


1. Check the computer for changing output (some computers use <F5>, <F8>, depending on which brand they are. I believe Sony uses <Function><F7> or <F7>).
2. Check what channel the HDMI port is on (e.g. AV1, HDMI1, HDMI2, etc.) - you need to know this if your TV doesn't automatically switch to the new input.
3. Plug the HDMI cable into the TV HDMI cable-in port.
4. Plug the HDMI cable into the laptop HDMI cable-out port.

5. Turn on the computer.
6. Press the <Function><F7> simultaneously ONCE. The screen should flicker and show up on TV.
7. Sometimes you may have to go to "Display Preferences" and select Dual Monitors or external monitor if your computer doesn't do it automatically. Repeat Step 6 after.

** You may have to adjust Display Resolution to 1024 x 768 or lower in order for the TV to work. After it works at a lower display (800 x 600, for example), you can adjust the resolution to the maximum the TV can accept.
