LG 42in plasma - Green dots on HDMI channel

I have an LG 42in Plasma HDTV, and for some wierd reason, when ever i switch it over to the HDMI channels, small green, pixelated, random dispersed clumps of green spots appear on the tv screen. The problem seems to correct its self after the TV has been on for a while but i really dont know what is causing the green dots to appear. It doesnt occur when i watch digital television or on an other channels apart from HDMI 1 & 2. Can anybody shed anylight on the situation?

Cheers, Will

    Hi

    I've got 42PT85 from LG aswell, and I experience the exact same problems. I've just contacted their hotline, and they will send a technician to try and ort out the problem.My problems started on HDMI2, but now it's on both HDMI's

    I had a loudspeaker placed on top of one of my HDMI cables, and thought that was the reeason - but nope - removing did'nt help.

    also tried exchanging the cables without any luck.

    Apart from that I'm satisfied with the tv.

    i have the LG 42PC56 screen and have the same problem your describing. I only get them when running my HTPC through HDMI 1 or 2 or the PC input. DVB seems fine along with other HDMI devices. Its really an annoyance.

The diffusion is slightly out of adjusment. This timing adjustment is difficult and on a single scan LG plasma the proper operation requires voltage settings first, then a scope to finalize the adjustment. I have good luck with this alignment by eye but have had alot of practice. This will require taking the back off and a person with the technical background to set this alignment properly. Sorry no easy fix.

Not widescreen on regular channels only hd channels


Sounds like a setting in the cable or satellite box or how you have the TV connected. Using HDMI it should resize automatically, but again it could be a simple setting in the cable/satellite box or in the TV itself.

LG Plasma TV Buzzez when HDMI cable is connected, not all the time just randomly. different stations different times, why


HDMI is very prone to audio problems--the advantages of HDMI are just one cable combines all---Issue if using a box or only on certain channels could be coming from the box if used.

If using component connections and no problem at all-it likely is not the set.

HDMI sets sometimes require a software/firmware update to resolve issues here--if random it is going to be hard to resolve.

HD channels look terrible


You may not have the resolution set to hd even though you are on the channel. Confirm that you are using hd cable and your set is displaying 720p or greater. This will sometimes pop up on the screen when you tune to a hd channel. it sounds like you are on 480 i or p. good luck

LG Plasma Green Screen


First thing to do would be to check your cables feeding into the TV. If you're using component cables, it's likely that your red and blue cables have come unplugged and all you're feeding to the TV is the green signal. However, if you're using a different set of cables or they're all plugged in properly, I would first suggest swapping out the cable for a new one. In newer televisions, such as yours, each of the colours is transferred through separate channels regardless of the type of cable used.
If either of those don't help then I'm afraid you've got an issue with the charging of the phosphorus gas itself, either it's not receiving the power correctly or some of the gases are remaining inert and not charging. If you're at that stage, you need to seek technical assistance from a service depot or LG.
Best of luck!

I have a LG 42PC5D plasma TV and there's a sound delay on all channels. I'm using a HDMI cable from a Comcast DVR convertor directly to the TV. Is there a firmware update that's needed? If so, how do I...


firmware is mostly used by commercial TV´s, try using your TV with other device or an aerial antenna.
I believe the problem is your comcast DVR convertor.

Low sound on my Vizio 50" plasma


Most of HD channel broadcast in 5.1 channel sound. Regular channel broadcast in 2.0 channel sound. You TV only have 2 speakers so you will expect the sound will be low compare with the regular channel.

Hope this will help!
