Question about Televison & Video

1 Answer

I'm not sure of the brand of my flat screen TV. But i think it might be a 32 inch sony. But it worked fine last night. I woke up this morning to turn it on with the remote and all it does is click like it's going to power on the shuts off. What seems to be the problem or what can I do?

SOURCE: tv won't turn on no light in front

I had the exact same issue . The TV literally stopped working 2 year after the manufacture date. Since I had nothing to loose I opened it up and found that the fuse had blown. I put a new one in and if blew also. I work with some electrical engineers and they said first to look at the Diodesmag-glass_10x10.gif. They lent me their diode checker, and the first diode I checked was bad. I'm sorry I don't have any pictures but it was one of the diodes closest to the where the power cord connects to the board. I took the board out and brought it to work and had the electrical guys pull the diode. I got a replacement diode, (.20 cents or so) and had them solder it back in. The Diode number is IN540, you can buy these online, DIGIKEY.COM is one place too look. I took it home put everything back together, including a new fuse and BOOM it fired right up. I did this about a mounth ago and it is still going strong, I should probably knock on wood right about now. If you have an questions please feel free to ask. I am not a TV repair guy, just someone who got lucky. Good luck!

An earlier post of the smaller model of this with the same problem said to remove the metal cover over the power supply.

I have the 26MF231D and it worked great afterward (even though you can't mount it)

Here is how you remove the cover.

SOURCE: Protron pltv3250 32 in. lcd, no power, no lights

You will have to have the set checked by someone to confirm this,
but most likely there is a problem with the TVs internal power supply.

SOURCE: Tv wont turn on worked fine last night

If there is no power at all, then the problem is likely the power supply unit.
The PSU must be tested, then eventually replaced.

My Hitecker 32 inch TV suddenly will not show any inputs other than TV. Worked fine last night. Doesn't this morning. No power surges that are known about overnight.


Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
