    Thanks for getting back - the model is:Toshiba 32MW7DB 32



    The ghosting is only through the S-video in - but is the same through the back socket, and also the front socket both are classed as EXT3. Same on 3 different DVD drives. It is NOT apparent tho through the SCART connection from the digibox on EXT1. This is what makes me think its not the tube, but rather something else - perhaps the s-video processing? Thx in advance....

There is no convergence adjust in a 32" tv. Convergence is done when there is more than 1 picture tube, ie; 50" projection sets have 3 tubes so convergence can go out. post the model number of your set and we can help more, BMW Rider

My Sanyo Vizon 32 inch flat panel has times when part of the picture becomes a "white ghost". How do I adjust?


Actually that is quite a rare case on today's modern digital flat panel TV's. You're not saying where you live, and you're not saying if you have previous issues on older TV you had before digital, and (again) you're not even saying whether you're on a hill or deep into a gorge. No TV has ghosting these days, but if you're living in an area as above, go see the TV people and they will probably recommend a set top box. But that isn't really necessary if you have a modern flat screen TV because most of these TV do two things, they give you a crystal clear picture or they don't. Digital TVs have a channel searching system that does the searching for you, and, as the case may be, these only pick up the best channels that give the sharpest picture. Anything that is of poor reception they ignore, so you're actually missing all the channels available because of this ghosting issue. AN there is nothing to adjust on the ghosting, snowing and vertical or horizontal bars, etc. These issues are things from the past, e.g. old analog TV's.

Hey, i have a samsung ln32b360, just 2 months old. worked beautifully when i got it, but recently it started ghosting a little in very specific situations. then it started ghosting a lot, but only in dark...


Hi,

First,If there are double images or "ghost" images on the TV's picture, check the cable connections and make sure they are secure.Because the loose cable connection would be a chance for the ghost picture

But if the cable is perfect and if you still get ghost picture then here is the solution:

The LCD Panel is defective. The problem is the T-con board that is used to decode the signal from the main board to the LCD Panel. The only way to fix it is to replace the whole LCD Panel or T-con board if possible. The T-con will cost about 1/10 of the price as the LCD panel but except for a few new models, the T-con is not available. The LCD Panel is very expensive (usually from $600-700 for a 32" Sony).

The reason is that Sony makes the T-cons for each individual TV with different specs to match that of the LCD panel because of the low threshold for error between the LCD Panel and the T-con.

Its best to avil warranty and change the panel...

Please leave me comment, if you need furher assitance

Visual transparent lines at top of picture


You have a vertical output circuit problem. This was common for Philips' sets. Have a repair shop check it out. Should not be too expensive to repair.

White lines & inverted picture at top of CRT TV image


This problem is normally the Vertical filter capacitors. You need to have them changed before it burns out the Vertical Chip.
