Question about LG RU-44SZ63D Television

DVI Input Shot

About 2 years or so into ownership, my DVI input stopped receiving signals. I hooked up the component cables to get the pictures. Since I already had a bulb blow in a year and a half, setting me back about $220 (with me doing the bulb replacement), I was hesitant to invest more into the TV with prices going down all around. I bought a Blue Ray Dvd player as a test and it couldn't get signals through the DVI (with converter to HDMI). Any thoughts? Had TV about 3 years now and not ready to shell out for new set when it has a great picture but would like to go to Blue Ray which needs HDMI.

    Thanks for the quick reply. I opened up the TV back but eventually had to abort. The back panel opened to a tray, with the connectors all laid out infront of me. Unfortunately, the DVI was encased in a steel, perforated box. The DVI input was the one facing the back wall, and output to another DVI cable on top, I assume filtering inside the box. It looked like a card inside the perforated box and I don't know if the DVI connnector is connected directly to the card or with wires. It looked and felt very sturdy, both before I removed the back panel and once the perf box was exposed so I can't see it moving to dislodge a solder joint. Since I would have to remove the tray to try and access inside the perf box, I opted out. Too many wires towards front of TV would need to be handled, etc. Since TV was stilling working well, didn't want to chance it. Question: When I hooked up my Blu Ray DVD and it was set to auto detect to the DVI (with Hdmi connector), it didn't come up NO SIGNAL but there was no picture either. I changed the video format (per BD DVD instructions) then it came up no signal. When hooked to the DVI, the BD player indicates HDMI on the front panel but I don't know if that was just because it recognized a connection (good or not) or if there is some connection. Any thoughts?

Hi Alanx,

In most cases like yours, the connector has a bad solder joint inside the TV. This occurs from strain from where the HDMI cable gets bumped or bent against a wall or something drops on it. If your skilled and brave, you can go into the TV and check the DVI conector and how well it is soldered in place. Repair the solder joint if this is the case. Good luck. Just think of how proud you will be to have repaired this yourself.

    Hi Alanx,

    Get the board numbers from the board that the DVi connector is located. Go to and see if you can get a replacement. Also look inside the DVI connector with a flashlight to see if the connections are in disarray. May be an easy fix. Yes, the BD is recognizing a hookup good or bad. Good luck. You do have the courage, go for it.

Hdmi will not work only use of component cables will.


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

No picture with Yamaha 6130 reciever. have

The TV must be tuned to the correct input also. Please cycle through the tv inputs by pressing the input button on the tv one time, then wait 5 to 10 seconds for the tv to recognize the input signal. If nothing, press again. You don't say which tv you have but many newer models have 5 to 7 input sources you will have to cycle through to find your signal.

With out more information, this is just one step in finding out what could be wrong. Please rank me accordingly.

Good luck.

I would like to know if I can connect a HDMI cable from My tv model WS-65315 to a Direct TV HD receiver?

NO> If your TV supports and have HDMI connections and your HD receiver has an HDMI output then you should have no problem displaying Video. Just make sure you change the input signal of your television to HDMI input. After looking at the spec's of this model these are the following inputs you have. your best picture quaity would be to use componet cables instead, which can show full screen 1080i format, your television does not show at 1080p whis is what HDMI is known for.
Rear Input Connectors S-Video x 2 - Component x 3 - Composite x 2 - DVI x 1 - RF x 2 - 1 x RS-232C - Audio (RCA) x 6

Front Input Connectors S-Video x 1 - Composite x 1 - Audio (RCA) x 1

Rear Output Connectors Composite x 1 - Audio (RCA) x 1 - RF x 1

Another good option is use to use a DVI to HMDI connector and hook it up this way. But note: you will have to use audio cables for the DVI input.

No input detected on projector

it sounds like the A/V reciever does not upconvert the component signal to HDMI. Not many do. The Marantz recievers will (SR6001, SR8001, etc..). Also bear in mind that HDMI cables are finicky and may require amplification over a few meters long.

This TV won't support 1080!

Low or poor signal from the cable company. Try another signal source such as a DVD play.

Picture problem

I have the EXACT same problem with my Sony SDM-P234 23" HD/computer monitor. I know it works (and it works great) with my DVico PCI card with my computer. It outputs in 480i, 480 p, 720p and 1080i with clarity on a simple indoor RCA HDTV antenna. I get the same quality (1080i) picture for the same three seconds as does lewy. I can also add that the digital coaxial output delivers 5.1 audio to my amp and it stays on even after the picture cuts out. Please help.....Comcast sendsa 'technician' out to service it and...well....did I say he's a 'technician'? He changed the box twice and says it must be my equipment. I guess its an act of God that it works with anything else.... I mean....its been checked out by a Comcast 'technician' after all.
