My TV's HDMI port/s no longer work! Do I throw the TV away?

No! I am not a fan of just throwing something away that, could be resurrected rather than, add to the Worlds WEEE  electronic waste. Replacing the TV could cost hundreds of pounds when, devices exist that cost between £20 and £30 and could give you full functionality of your TV again, bypassing the faulty HDMI video control chip.

I am aiming this article to the everyday TV user not, the electronic geek.  A 'plug n play' solution.  However, some of you might have researched and seen that you can fix electronic devices by, ' using a Hairdryer / Heat Gun on the xxxx chip' or, ' baking the xxxx circuit board in an Oven'.  Let me dissuade you from this please. The resulted 'fix' seldom lasts long and could even fail and you end up with a useless (dead) TV.

The technically savvy would know that you can buy replacement (fully working) circuit boards for around £30 but, I am not aiming this article at those people.  They don't need my help. Also, in this disposable World, it can be hard to find such replacements for an old TV.  For instance, I could not get a replacement board for the LG LCD TV I have that, was manufactured six years ago.  A major grumble of mine and at the time of writing, the EU are proposing law that forces manufacturers to make electronic devices last longer and be more repairable.

Jumping straight to the answer...
Look at the back of your TV and if you see three sockets that say, 'Component Video In' then, buying the following will get you back up and going:-
1 x HDMI to YPbPr RGB Component Converter
1 x Component Video cable
1 x RCA Stereo audio cable

Component YPbPr video will still give you full HD (1080p) quality.  The Component video lead has separate 'Red', 'Green' and 'Blue' connections that carry the video from the converter, to your TVs 'Component Video In' connections.  The RCA Stereo audio cable carries the audio left and right channels from the converter, to your TVs Component audio connections.

If you think that this is just too many unsightly cables, the converter device is small enough to be hidden from view. Even use Velcro to stick it behind the back of your TV and use short cables. No one will notice.

If you don't have an AV Receiver / Amplifier and want to connect multiple HDMI devices to my above solution then you will need to also look at getting a HDMI Switch device. There are many available and can allow anywhere between three and five devices to be connect to a single HDMI output that, would then be connected to the converter mentioned above.

My story in depth

A work colleague gave me an LG 47 inch LED TV featuring 100Hz, 1080p HD and Freeview HD.  He was throwing it away as, the HDMI ports had stopped working.  He just went out and bought a new TV.  Yes, he was probably better paid than me! Thanks Scott!

All my AV devices connected to my Onkyo AV Receiver which has six HDMI inputs and one HDMI output which, I would normally have connected to my TV.  So, I would normally have only one HDMI lead connected to the TV.

For completeness, connected to my AV receiver are:-
Blu-ray player, FreeSat PVR and a DIY Kodi Media Center that I built from an old PC.

Sadly, I could not get a replacement circuit board for the TV so, I looked at other options.  It just bugs me when, an otherwise good device is crippled by the poor manufacture of a single semiconductor chip.

Most modern TVs come with a plethora of connections.  If you look at the back of modern TVs it can be quite daunting.  HDMI is the latest connection that gives you a single socket to connect your full HD (1080p) devices to your TV.  It is by far the most convenient way to plug an AV (Audio – Video) device in to a TV.  Thus, most device manuals don't go in to detail about the 'other' connections (sockets) on your TV.

Before HDMI, Component video (YPBPR) was an alternative and can be found on most A/V Receiver, Blu-ray players, DVD players and LCD video projectors.

After five months use, my Porta died. I contacted the supplier who, were the manufacturer and they sent a replacement. However, it was only the mains adapter that failed. So, I ordered a 5Vdc 3Amp mains adaptor and got the original going again.

Below is what I bought and is an example only.  There are other brands out there.
HDMI to YPbPr RGB Component Converter
Component Video RGB YUV 3 Phonos To 3 Phono Cable Lead 50cm 0.5m
Twin RCA Phono to RCA Phono male audio lead 1.5mtr
