The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Baird tv has no picture but sound ok. picture lights up when turning on and off but then goes out.y


Hi Anon,
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
If your TV, flatscreen, or monitor is more than 5 years old it is more like to have suffered a component failure.
Take it to a repair shop.

Keeps reseting itself


Dude check your A/V or HDMI cables or whatever you use. HDMI cables can be tricky. Make sure that the different shades of color are matched up exactly. Ex: make sure light blue isn't plugged into the dark blue slot. it may not appear as if it matters but trust me it does.

No picture, but sound


The backlight inverter board is most likely faulty and requires repair or replacement. Shine a torch close to the screen and if you see a dim picture then this will confirm a faulty backlight.

Compatibility with Samsung LCD Display


It sounds like the HDMI port on the back of your Marantz is damaged. if you know for sure that the HDMI port works on another tv still you might just use component connection because the visible difference between component and HDMI is not very recognizable.
