Hi all and Happy Thanksgiving!
This Tv came in from Illinois (5 hours away) with the customer complaining of red sparkling halo effect and I thought he was talking about reverse picture;
We plugged the Tv in and it ran great for the first three weeks. Then, it started to act up. Kinda like a negative or reverse picture.
The customer was in town and we had him come in to look at it... He said that was the problem except it was red... Our symptoms showed Green.
See the following pictures.
The first thing we did was to clean the T control ribbon Connection and that did not change anything. We tried another T control Module.. Nothing changed.
Got to thinking it was going to be a main module except ShopJimmy was out of them and the next price was 200 plus dollars..
So,,, did so more checking and tapping... Tapped around the power supply module... and this time... the picture changed... Did more tapping around the top side of the panel thinking it could be the problem... picture changed again...
See ribbon connection going into the main module picture.
The shielding was on before so we were not able to tap around the connection itself but there was enough tapping that it did show up. So I removed the shield and wiggled the connection... and it showed the effect from either red (customer complaint) or green...
We cleaned the ribbon connector.. and the set has been rock solid with a clean picture.
I wonder how many main modules have been replaced but it was the ribbon connector that was dirty and the main module was okay.. Hmmmm
Hope this helps someone
