Question about Philips 27PT6441 27" TV

1 Answer

Picture problem The color on the tv goes in and out all the time. It goes from being right to going really dark and then light. I have tried many things like replacing the cable that goes to the tv to a expensive cable that is supposed to be excellent. The tv is only about 4 or 5 months old and I am ready to throw it out... please help me try to fix it.

Re: picture problem

It sounds like to have a problem in the video circuit or the Hi voltage circuit. If you know how to fi8x electronbics then get a meter and monitor the b+ on the crt drivewr transistors. See my point . WQe cant tell you exactly what the problem is and teach you how to read a circuit diagram, and to solder. These sets have a high voltage in them even when they are unplugged so you shouldnt really touch these puppys as there are no user serviceable parts inside these sets and should only be done by a quilifyed service tech!! If its only 4 to 5 months old there should be a warranty on the set so you shouldnt touch it as well just for that reason. You should be looking up in the owners manual for a servicer or # to call to find one to fix it under the warrantee. good Luck

The Contrast and Brightness on tv appears to be dark.

If this is a CRT-based TV and it's been played most of the time, you may have a bad picture tube, especially if strong red colors bleed to the right. CRT's dim with use, unlike LCD or plasma. But it could also be trouble in the video circuits - none of this falls into the DIY category, unfortunately. High voltage involved, unless you're comfortable around it and want to try turning up the screen controls inside the TV. If you do, let me know - but "no response at all" from the external adjustments points to a more serious problem.

Adjustable Color Temp. The Adjustable Color Temperature feature lets you adjust the color balance on your TV, depending on the type of light in the room, such as direct sunlight or artificial lighting. On your remote control there should be a button that lets you change the picture mode, IE. Rich, Personnal, Cinema, Sport etc...

Colors are distorted, brightness excessive

You may have a bad Fly Back transformer. The focus and screen(brightness) controls are located on this transformer. Some of the new RCA's have had problems with this transformer. If the screen control opens up the picture may either go dark or light which would cause your problem. Also a bad Picture tube could cause this. It shouldn't since the tv is not very old though. I've seen a few new ones go bad. Stargazer

Dark picture (HELP)

Open up the back of the set but be very carefull. Notice a large black block with a large red wire that runs up to the picture tube. on one side of that large block where the thick red wire is comming out of are two controls, one should be marked focus or F and one should be marked screen or S. With the set operating normally and not touching anything else, slowly turn the control marked screen or S clockwish till the picture gets bright enough. If you go too bright the set will shut down or you see small thin white lines so back down on the control. then touch up the focus and your good to go. good Luck.

Brightness and volume

The dark picture is a bad capacitor for the screen or drive voltage for the picture tube driver transistors. The other problem of streaking is one of the same. Thats the indication that a capacitors defective . It could in a rare cas ebe a defective or gassy crt as well but 99% of the time when a crt is said to be gassy its nothing more then poor drive to the crt. Good luck
