Question about Televison & Video

No red in picture

I have a Phillips Tv, 55 inch projection hdtv, approximately 5 years old, but with only about 3 years of use on it. A few weeks ago the picture began to lose its red color intermittently, now the picture has no red at all, but it does continue to flash red lines here and there. Any ideas?

Thanks!
Holly

It could be a dry solder joint on the base socket pcb. Try resoldering the base socket, and try for dry joints on the main board also. Check if the rgb voltages are steady on the crt driver transistor bases.

Red wavy red line on top of picture.faces distorted, but bottom part of picture ok


sounds like you have an output power supply going bad.

the tv is crt projection...which is to say due to its age and technology it will probably be cheaper to just get a new tv.

Sometimes these older style sets end up with compenent board solder breaks that can be spotted visually and fixed by a talented repairman.

My friend had this done to a similar 55 inch set he has about 3 years ago....he just won't give his up either!

good luck and be careful! There is lots of high voltage inside that tv!

Clearer HDTV picture?


quite possible that the coolant is getting contaminated as thats a normal occurance with phillips after a few years. If the color seems dim and not focusing properly its almost certain that the CRT coolant will need changing

Problem w60 inch using hdtv cable box


i know this problem, happened to me with the comcast Motorola HD receiver box. The key is with the setting in the cable box. Switch on the TV. Set the channel to normal tuner channel 3 or HD input. Turn off the cable HD box. Press the Menu Button on the Cable box or the remote. You should see a Menu. Use the cursor keys to navigate The default setup is also one of the option, Right click on your cursor keys acts like the computer keyboard enter key and applies the change. The default setup is 16:9, the shacking would happen if you have set the picture type to "PAN SCAN". change it to either 16:9 or 4:3 Letter Box. The shacking should stop. Hope it helps.
