SOURCE: goodmans flat screen TV.Blank screen

If it is a LCD TV, and there is a faint picture, it is probably the backlight or inverter board (probably the latter). This is a common problem (especially with PC monitors).
Do an internet search for your model and inverter, you may be able to replace it.
Make SURE you REMOVE the power lead before opening the set !!!!

SOURCE: TV No Picture

My 32D40U would turn on for 5-10 seconds (Please Wait would appear) and the screen would go black. Sound Normal. It would also sometimes do this after running 5-10 minutes. I read somewhere that the inverter board would come loose and lose proper ground. I took the set apart, removed the board, and cleaned up the grounding points. I reassembled using some copper paste on the ground points and LockTite on the screws. I used some contact cleaner on all the connectors going to the board. I noticed two cables that are covered with copper shield tape where too tight at their connectors and repositioned the tape to give them some slack. The problem hasn't occurred since the fix.

The aspect ratio (zoom) button on the cable remote had been changed. On Brighthouse the # button toggles through the zoom settings. It's not a tv issue, it's a cable fix.

Toshiba 37XV505D. Sound but no picture


Hi,
Since sound is ok but there is no picture, you should try the following:
1) check whether brightness & contrast controls are adjusted properly. If necessary increase level of these controls.
2) If brightness & contrast are ok and even then there is no picture then most probably, there is fault in the horizontal supply circuitry which drives picture tube and is responsible for picture to appear on the screen. you will have to take the TV to service center.
Good luck and Good day.
Rating the solution is appreciated please.

White/Grey screen with non-HD channels


I removed the HDMI cable and connected with component video and rca audio. No more white screen.

Picture quality looks good. I don't know if it's as good as HDMI, but then I don't need to reboot the TV three times to get to teh on-demand menu... Grrrrr....

I am trying to contact Toshiba on this as well. I have seen several reports of this problem on the web.

White line accross screen holds when picture goes up and down.


This can be caused by the contrast being set too high. Typically, for a Sky box the TV's contrast should be set to around 65.

If this does not help, then the LCD panel is probably at fault.
