Question about Philips 42TA648BX 42 in. LCD TV

1 Answer

Audio but no picture, just blue and black screen

I first noticed a few days ago that the tv had large black square in the middle as it was turning off. Now the Philips blue and white screen comes on as usual upon starting, but then converts to blue and black jumble but audio still works. I tightened all connections and it is not the cable. This is a reconditioned tv, approximately 18 months old. Help!!

Hi


Thanks for using FixYa. From what you have described it seems that you might have a backlight and/or an inverter board issue with this TV set. It could also be due to the inverter circuits for the backlights. The inverter is the power supply source for the backlights. There could also be a screen driver problem; if it is then you have to change the entire inverter board. All this is only recommended if you have some kind of expertise for checking the internal circuitry of the TV as these units have high voltages running even when the set is switched off. The cost to change the inverter board including labor would be around $250, if you get this done by a professional. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

Large black square blocks screen


Most likely it's the closed captioning has been turned on. From your post I assume you have the remote control and able to access the menus so try to turn off the closed captioning. I'll be notified if you post something new.

those are going to be dust spots on the LCD panels internal to the optical engine. i suggest that you take the screen off and take off the panel i nthe middle of the tv with 2 screws in it and there will be an area that has 3 metal fins covering thin orange ribbon cables. the 3 square objects at the end of those ribbon cables will be the LCD panels spray wiht air compressor unitl clean and that should greatly help your problem.

Black screen


I have a Sharp Tv that had the same problem with a large brownish or black square right in the middle of the screen. It only left about an inch around the edges that you
could see the picture moving in behind the big black block or square.I have DISH sat-elite and the book recomending that I check and see if the "caption settings" were on
or off. They were on. I turned the caption settings off and the large square diappeared.
