Question about Televison & Video

1 Answer

Hello! We have a Sony Bravia 42in LCD tv (KDL42V4100). Our house was struck by lightning and we had to replace the power supply board part in the television, and it now turns on and works. Now the problem we have discovered is the TV says it has no signal from anything we plug in any of the HDMI ports, like our digital cable box and playstation 3. We have tried these with 2 different HDMI cables, and neither worked. Any suggestions on how it could be fixed?

Hello,my Sony Bravia HD TV (LED & LCD) we suspect that it was struck by lightning,but my other appliances connected on the same power cord as my tv are working fine,so i'm confused..


The power surge from lightening can come in thru the antenna or cable box. Also just the proximity of lightening can damage one item and not another. An ic chip can be destroyed from the charge in the air.Likely took out power and main brd both.

MY SANYO LCD TV MODEL 24 K 50 WAS OFF WHEN LIGHTNING STRUCK NEAR OUR HOUSE AND SINCE THEN IT DOES NOT TURN ON


Replace or have the powrer supply tested and eventually serviced.
Lightning strikes affect two types of boards in televisions - the power supply by means of entering through the AC line and main boards by means of entering from the external signal sources. External antennas are worst and can totally toast the main board whereas a signal entering through HDMI cable from another device is less likely to be affected by a power surge.
So naturally you start your quest with the power board , which is the usual suspect.

As of right now I do not believe we have an announced service for the power supply board of Sanyo LCD-24K50, but if you do not have any other options you can always try and send the power board for examination/repair through

Sony bravia lcd won't power on after lightning strike


I am sure the tv is shot from the surge but you can check a few things. I would take the tv apart and test the power supply first. Look for obvious burn damage throughout the boards. If there is a blackened one (prob video board) then you can try to replace that. Don't worry about taking this apart and breaking it further. In this case it can only get better for you.

Sony bravia kdl-42v4100 no picture no sound if i disconnect cable running from controller board to main tuner board i get sound but no picture and if i plug it back in you see a picture for a second then...


Hi,

Sounds like there is a short on the power board or the power board has gone faulty.

Look on the power board to see if any of the capacitors are bulged or if there are any other components burnt out. The TV is going into protect mode because of an over current, which points to a short on the board or a component has gone short circuit.
Thanks

Struck by lightning and won't power up


WOW!
Warranty voider there.
Hate to see a $1,000 TV go down the toilet.
If your lucky, you can try checking the fuses inside the TV.
The lightning may have taking out only your power supply board, shopjimmy.com may have replacements for about $100. But, I can't tell you for sure that will fix the problem.
You may have to take to a repair shop to find out for sure.
Good Luck
