LG - 42PX5D Input switching problems

Please help, i brought an LG 42PX5D just 5 months ago and lately it seems to have developed a fault. The problem is that i have many different components connected Sky (AV-1), X-Box (AV-2), DVD Player (HDMI) and X-Box 360 (Component) and when i switch from one to the other the TV occasionally freeze's/crashes. The green light stays on but the "input" doesnt change. The only way to recover it seems to be pull the plug and start again (when it will be fine untill put back into standby) This fault only happens occastionally which makes it even more frustrating. If anyone has any information about this problem i would love to hear it. ROCK-ON!

    I have a similar problem.  I have everything running from my receiver such as my blu -ray, x box, wii and direct tv.  I will watch a movie and when  I switch the receiver from the Blu ray to the direct tv it is like the tv zooms and the picture is shifted to the left.  I have no idea why it does this, anyone have any ideas or and idea to help fix it?

    When a DVD or gaming system is plugged in through the input component; the picture is black and white. No problems when plugged into av input

I think the problem stems from the HDMI port and scart ports, i have read somewhere on a sound and vision web site that these two conflict and when HDMI is in it only sometimes blocks out the scart signal. This could be what the problem of the freezing is, as when all said and done its just a very large pc monitor; and look at the trouble they can get in!.

Sounds like main system control memory IC fault. Contact any service technician. The tests related to this fault is somewhat skilled work, and need proper testing equipments, and experience.

Hi,

The issue seems not related to the LG Burners, possible the disc in which you are trying to burn may be issue.

Can you try with the different brand disk.

Call your LG dealer for a service call out, this sounds like "sparklies" adjustment is required. If adjusting does not cure the problem then there is a software solution that the engineer can apply to cure the fault. There is nothing you can adjust yourself without removing the back cover.

I am looking for either LCD or Plasma TV 40-47' that is CableCARD slot equip. I found a couple offering the LG 42PX5D claiming it has CableCARD However when I look at LG specs it seems to say it does not....
It is Digital Cable Ready (CableCARD)

I'd stay away from them personally because of the following reasons:
1. No video on demand (VOD) or electronic program guide (EPG)
2. No PVR function - would require a PVR to record
3. CableCARD units cost more
4. CableCARD may not get the latest channel releases
5. Customer support is lacking as not many people are using CableCard

There is a fault in the main processor that is causing noise. The set will have to be serviced. The tech will probably try the main video processing board to start.

Send it back ASAP and get a replacement! I'm serious. You wouldn't want to baby sit this lemon by missing work because you're waiting for a home service tech provided by the company. When the tech comes, he will not have the part required to fix the unit and you'll be waiting at least a week to get another service call. That's another day missing work. You are one lucky guy if the servicer can totally fix the unit to your satisfaction in two visits. Days missed at work could very well add up into buying a new TV. Do not take ownership of this problematic unit especially if you just bought it. Send it back!

Brought the set to my local TV technician last night, he's going to call me today to inform me what the problem is. He's indicated that it is mor than likely the y-sus board whcih will need replacing, apparently for these HD sets they're not cheap, around $500 - $600.

After having done a bit of research I had looked into sourcing the boards (apprantely some come in a kit form, 3 boards included) direct from the Australian Supplier (Statewide Appliances in Adelaide, SA), however it turns out I was sourcing boards for a different model. Pity as it was only around $100 for the kit.

Will keep you posted!
