Question about Toshiba Televison & Video

1 Answer

What is causing my LCD tv to turn off on my Toshiba 52hl167 tv.

My tv recently went blank. I do get power and do get a green light and can see image when I shine a flashlight so I assume it was the backlight inverters that went out. I replaced the backlight inverters and now the tv does turn on but for only a second. I noticed when I turn on one of the inverters seems to make noise and it smells like it burns when I try turning it on. What could be causing this? Power supply? Bad LED lights? Is it normal for the inverters to make a type of buzzing noise? Maybe it wasn't the inverters after all? Thanks for the help

. 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. http://electronicshelponline.blogspot.com/ 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. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

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.

Take it to a repair shop.

TV does not have a picture. I'm assumming it is the bulb. Where can I purchase a new one?


Not likely, this TV (Toshiba 52HL167, http://www.amazon.com/Toshiba-REGZA-52HL167-52-Inch-1080p/dp/B000MY08GA) uses CCFL (Cold Cathode Fluorescent Lamp) for backlghts, most failures are due to bad power supply, bad DC filter caps, bad Backlights inverter board.
It will require in-depth troubleshooting.
If you decide to DIY repair, then you should read my guide first.

This will most likely be down to your screen controller board, Take the back of the tv and look towards the top middle, You will see your screen cable go into a rectangular board this is sometimes covered by a metal plate, remove this and check Ebay or Google for a replacement, there will be a part number on the board
Hope this helps?

Toshiba 52HL167 52" HD LCD


I have similar problem. Sometimes it will show only a blank screen. Just unplug the AC cord, wait a few seconds and plug the AC cord back in. This will reset the processor and the picture is back. It happens once a month. Not a big issue to call warranty service.
