Having problems with flashing screen on my LCD

I have a samsung 68cm LCD, its hooked up to my DTR8000 dick smith set-top box. I have a great picture but the screen goes black occasionally and then starts to flash. I turn off everything and try to re-set but this often doesn't work and the screen keeps flashing. I'm getting the shits with it and hope you can trouble shoot for me

Re: Having problems with flashing screen on my LCD

This problem sounds like the main video board. Try this... take the back panel off the tv and on the right side, take the cover panel off the board with all of the inputs, next, take a screwdriver and with the handle of it, tap on the tuner (this is the little shiny metal box with 1 wire and multiple connections soldered onto the main board) and see if the screen goes blue or loss of picture. Note: tv must be powered on, and with a nice clear picture in order to see results. If this is the case then you will either have to get the main board and replace it

Dick smith tv has no display

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.

What is wrong with my Samsung Television? Screen issues, but perfect audio.


a picture would be great, what you are describing would be a number of things. Being that it's a Samsung, I would suspect a failing LCD panel, very common with older Samsung's and Sony's. Other possibilities are a bad main board or a damaged LCD screen. I guess I should ask if the problem is always there or does it go away when the set warms up? If I have been of assistance, please sign my guestbook!

Sony Bravia - picture don't fit the screen

I have a Scientific Atlanta cable box w/ Time Warner. I followed the instructions below for the cable box. Somehow it reset my picture and I can now read the ticker at the bottom of the screen and the different picture sizes seem to work properly. Good Luck.

Picture issues

Greetings caesar975,

Unfortunately if you chose to view the non HD channels in wide screen format, you are going to have the top and bottom of the screen cut off. Eventually this will not be a problem when everything goes to digital. However presently non HD channels are presented in 3:2 ratio where as HD is 16:9, So your choice really is to view them with the lines on either side for now.

I do not have an answer for the white flickering lines.

To get the BEST picture out of your 1080p unit I highly recommend using HDMI cables to hook it up.

I hope some of this helps.


Go Ahead. Use Us.

Samsung 40" LCD HDTV

Sounds like a different source is the problem, start by eliminating each source hooked to the set, I have seen cable boxes do this, see if it does it on a dvd
