Question about Panasonic PT-43LC14 43" Rear Projection HDTV

1 Answer

Screen Brightness You look like the best expert on this site. Can you help me? Over the past month, my picture has gotten darker and darker. I replaced the lamp (which had actually busted completely the day before my new lamp arrived and caused the TV to power off). I bought the Panasonic TY-LA1000 replacement lamp but not from Panasonic and the picture came back, but was still very dark! Its gotten to the point where it is unwatchable. Any suggestions?

Your ballast may not be up to 100% of its rated capabilities, thats often the cause when the brightness level gets to unwatchable levels. You may need to troubleshoot the ballast voltages a defective ballast can usually cause a lamp to loose about 60 % of its brightness levels. The other possibility could be the DLP mirrors need polishing but that is something better left to a repair shop as the DLP mirrors are sensitive

How do I know which part to replace in my LCD TV...is it the backlight or t-con or main board?


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

HDLP61W151 has dark spot in screen


If it happened gradually I would suspect the lamp--a photo posted here might help.

The other possible cause in a Optical light engine which might be very expensive to replace in this brand.

Samsung LCD 46 inch half of the screen is darker than the other half.


Hi, while fixing another persons lcd tv i used lower rated power supply to try to fire up the tv ( picture-no sound) the bulbs ( actually cold cathode fluorescent ) lit up but only halfway. So sounds like the power supply for your backlight has gotten weak. You may try a workaround I've used on personal equipment, try turning down brightness on tv-this may,if your lucky, even out the brightness. hope this helped. Prodzilla

Darker screen after replacing a samsung dlp lamp


DID YOU USE THE FOLLOWING LAMP
BP96-00826A (PHILIPS WRITTEN ON THE LAMP)? ALSO PLEASE CHECK THAT THE LAMP IS COMPLETELY SEATED OR IT WILL RESULT IN BRIGHTNESS ISSUES. THERE WAS ONE THAT I REPLACED THE LAMP IN AND I NOTICED THAT THE DIAL OPENING ON THE LAMP HOUSING WAS A BIT SMALL AND WOULD NOT ALLOW THE COMPLETE SEATING OF THE LAMP AND I HAD A DARK PICTURE AS A RESULT. I USED MY CORDLESS DRILL WITH THE PHILIPS HEAD STILL ATTACHED AND REAMED THE HOLE LARGER AND IT SOLVED THE PROBLEM.
HOPE THIS HELPS.

I think you are right about the backlight. You need to replace the backlight tube or, if you can, replace the TV. Good Luck.
