    I have exactly the same problem, although sometimes the screen just fuzzy's black instead of a still black/blue image. Works fine on VGA though.

What to change in this LG 50PZ650? TV powers on, but there is no picture at all, can someone shed some lights on the different components in the picture and what to replace Thank you in advance.

Hi , first, is the antenna attached and fully functioning? Attaching another device to it will show if this is the source of your issue.
If the aerial is okay and you can access the tv menus ensure the source is set to digital .
Then go into the menus available from the remote and find the option to reset to factory default. If your problem is not a hardware fault this should remedy it.
If after hard resetting the set still does not work the issue will probably be with the power control card or the mainboard.

video for the power control card repair here

The fault may clear if it does not you may want to consult a technician about diagnosing for you

My samsung tv model UN29F4000, has sound but no picture, no menus come up. I'm not sure if it has a tconn board or not. What is the most common problem with a tv with these symptoms

The most of this TV problem is that the inverter transformer built on the main power supply is bad, to fix it, you may replace the transformer , or replace the power supply module.

I have a 46 Samsung and when I turn on the TV I get sound but no picture. I get tv menus, sat menus, and dvd's work but no picture on sat.

The problem of your tv is only the connection or the digital receiver. Try to check the cables that are connected in your tv specially the input,output of the digital receiver or use another cable for the video in of your tv if still no picture try to contact your satellite service provider the unit is may be defective. good day and hope that it may help thank's.

If everything else works - there is sound and high voltage (static on the screen) - but there is no picture (including no on-screen menus), this limits the likely area of problems is the video output circuitry or CRT filament connections. Check to see if the CRT filaments are glowing. If they are not glowing, check for bad soldering on the CRT neck board and around the flyback transformer.

Where the picture is erratic - coming and going entirely or changing brightness suddenly, with power off, remove the picture tube socket (carefully!) and clean the pins with fine sandpaper and use contact cleaner on the socket. This source of bad connections can result in a variety of erratic symptoms. Check for bad solder connections on the CRT neck board.

Your video boards located near the power supply have failed. Unless you are skilled it is not A DIY job as they need to be matched. There are two and both may be involved. The caps can be changed but labour costs dictate it is cheaper to replace the boards than repair them.
