If you have a bright vertical line down the screen you have an "S" correction fault. Usually there is a small choke that gets a dry joint under it.
Check for dry joints.

SOURCE: (lg rf-21fc80ve flatron) tv audio ok but video is rainbow colour appers on the screen what this problems please help me

Hello
Replace its CRT connector socket. This part can be located at the base card of the picture tube. The contact to the pin number-1 [Focus], has the fault. It has corroded. Reppace the the connection socket. It can be bought from most of the electronic spare part selling shops at your town. Desolder it out from the base card, and keep it with you as sample, when you go to buy a new one.

depends on age of set and cost of boards---do some research with Google and the model number "parts" "boards" etc and by the way in these sets it can also be a power supply issue etc---almost but not quite anything.

My plasma TH-42PV7HS problem is after on first ok, a few second the picture over green. some people on tv hair is green colour. HELP ME!!


this means your tv has a intermitent problem when the clour ic gets heated up it starts to give you green..so therefore you need to take your tv to a tech to have it repair by replacing the colour ic. good luck.

The colour on my TV is awful, the colours are not true at all. Red looks orange, blue is glaring blue and sometimes the colours fade out a bit and then come back. I have tried adjusting everything but...


I presume this is a TV with a picture tube, and if so, it would either be the chroma decoder IC or the jungle IC which could be possible causes of untrue colour, as well as the small components around them. Electrolytic capacitors, especially those in the chroma decoder circuit, tend to change value over time. Check and replace these first before diving in and replacing ICs. If the greyscale tracking is OK, as well as the overall picture, then the tube is probably OK. If it is not, and the images appear washed out and blurry, then the tube is on its way out, which means only one thing: throw it away.

With any IC replacement, it is a good idea to invest in special IC sockets - these are available from most electronics stores for a small price (you then trim and solder the sockets to fit the board as required) this will make it easier to swap ICs in the future if necessary without further soldering.

Although tv is showing picture the colours only showing background etc are green and blue


Hello
Your TVs red colour output section has the trouble. There is no red output at the red cathode of the picture tube. The red, green, and blue output sections are on the picture tube base board. In some Philips model, these will be consists of transistors, and some has an IC or Tree ICs for three colour output used. You just open your TV, measure the voltages at these three cahodes. There will be markings on the printed circuit board for these cathodes marked as [Rk,Bk and Gk].
In your TVs case the voltage at the Rk marked pin will be higher that the other two cathodes. This can be caused by an open drive transistor or an Ic whichever may ysed there. If it is transistor, just replace it with a same type and number, as in the ace of ICs the related Ic, must be replaced. If only one Ic is uded for red, green and blue outputs, that Ic must be replaced.
If you need any more assistance, feel free to get me through Fixya. Ok.

No green and yellow colour


Hello
If you see the picture in yellow colour, means that there is no blue colour output from the video drive section in your tv, Yello is the mixtrure colour of red and green. Green is actualy there. blue colour is absent.
To detect this fault, you must open your tv. Just look in to the video output section, can be located at the picture tube base card, which is plughed into it diretly. See for any loose soldering points there. Check whether transisotors are used for red, green and blue output stages, or an Ic or three seperate Ics are used for this purpose. Anyway, blue catode of your picture tube pin gets a hig voltage, and so the blue emission is absent. You just check the voltages at red,gree and blue catodes, at the respective picture tube pins, which can be taken at picture tube base card. All of these three pin voltages must be somewhat equal to each other. In your case, no voltage at blue cathode will be higher that the other two. Check for the reason. It may be due to an open video output transistor [blue], or an Ic, of one Ic if used for the three colour outputs. Check and replace the same, will rectify your problem. Ok
If you have andy difficulty, get it to me through Fixya. Ok
