I have colored spots appearing on my screen when the TV is on. The spots are 2 to 6 inches in diameter and always appear in the same locations at various places on the screen. The first spots I noticed...


the light engine (optical block) is failing. there are lcd panels and light filters in the light engine. the problem your having is that they over heated and the image is burnt into the lcd or light filter. my be caused by a failing fan or just it's life span. the lcd panel or light filter are done for. you can keep calling panasonic and bug them over and over and they may send you a new tv. sony sent me one after 5 phone calls. i had the same problem. hope this helps.

No color TV on my Trutech 7'' LCD TV + DVD under the cabinet model KLV3170


The TV broadcast system in Brazil is PAL-M.
If this TV was bought from the US then the TV will be expecting the NTSC system.
Your other American TV may be a multi standard TV and is able to detect and adapt to your PAL broadcast system. Not all TVs do this.

How do you connect the DVD to the Trutech TV? Is it with a Scart connector? If so then the TV will not be using any broadcast standard at all and that is why it works properly.

Unfortunately if you have searched all the menus and manual instructions without finding a TV system selection, then this TV may never be able to receive TV broadcast in colour.

Color on tv


If this happens to all the input sources, the main logic board is fired. If this happens to only one input source, only that input source circuit is fired.
It is costly to replace the main logic board. And then there are other components ready to die out soon.
Your set is at least 5 to 6 year old. Have you replace the lamp yet? It is rated for 10,000 hours. Yes, it will fail in about 10,000. Off brand replacement is cheaply made, can cost problem. (mine did). The nut holding the wire to the lamp was loose.
Time for a new TV. A new 46-47 inch LCD is less than a grand.

My rear projection TV has color spots in the picture, most noticeable on light color picture


What is the make and model of TV. If it is a Panasonic that has different colored spots such as pink, blue etc. Then you need t6o contact Panasonic as this is a memory reset that they have to perform on the LCD driver board. Other brands of LCD projection sets that have spots that appear all over the screen mostly on white back rounds are almost always dust that has settled on the LCD panels. This requires a technician to clean the LCD panels if possible.

Panasonic PT-47WXC43G Red Color problem


This is a convergence problem; in the customer menu there is an option to adjust it----if red or blue will not move in some direction---one of the two convergence IC's is bad and both need to be replaced.

I have step by step instructions telling what you will need for this repair. They are in Microsoft word----let me know if you want them and I will email them to you. You can buy both chips for this set on Ebay for about 13 dollars plus shipping for a pair.

Panasonic hdtv projection colors will not line up


If only minor convergence issues, the setup menu has user controls for 9-point convergence. If it's major misalignment in just one color, you may have a blown convergence amplifier chip. Big bucks repair, unfortunately. Chipsare about 30-40 dollars apiece but labor will kill you if they'll even fix it on-site. Most try to order $700+ board which is no longer available. Teh they send yours out for -10 weeks at similar prices.

Hi,I have a Samsung LCD TV -Model LE40R82BX/XEU.The display is cracked and I have Rainbow colors down one side of it.I can take the tv apart and I want to put in a new LCD.Any ideas of a good cheap site[s]...


Unfortunately, the LCD panel itself may cost more than a replacement set. Check in your local area for a Samsung parts distributor. They should be able to provide you with the part number and cost for the replacement.
