Lightning will create a lot more damage,the vertical circuit has become defective,the repair should not be expensive better be safe and call a qualified technician.

What parts probably need replacing on my Pioneer plasma PDP-5010 FD after a home lightening strike?


Fault at its main digital 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. Pull up older posts. http://electronicshelponline.blogspot.com/ http://electro-medical.blogspot.com/In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Mitsubishi WS-5541 light blue glow


I know these sets pretty well--worked on a lot of them when new and later--one of two possible ideas=

1. Either a odd convergence problem==confirmed or denied by going into the convergence menu (in customer menu) and selecting advanced which will bring up a grid of lines--if see the same issue (I will attach a photo of a Mitsubishi with this problem) it can be fixed.

2. Some sort of issue with the circuit board on the end of the Blue tube(you are missing blue=black) but usually in this set if that happens it is uniform and on both sides of the screen, not the top.

Let me know what you find.

I doubt it is convergence, but does not hurt to look--if the missing area was perfectly rectangular I would suspect up/down centering adjustment.

There is one other possible thing to try--we will leave it for last--set has 3 hidden menus and one is OPTION menu which allows a hard reset of entire set--sets everything back to factory except convergence adjustments which are stored in another area.

My 50 inch vizio plasma tv has a 7 inch blue line down the center of the screen and there are a couple white half iunch lines in the center of that. if i hit the input button it will disappear and then...


Since the lines are vertical, the image is lost sideways and the corruption changes with the image then clearly this is a sign of Y-Sus failure, not the Z-Sus or the buffer boards.
An logic or input board failure would affect the entire screen, not just a part of it and a failure in one of the buffer boards would affect strictly defined lines of pixels and the defect would be constantly there all the time.
Since you haven't told us the exact model i can't point you to a replacement board.

I have a Toshiba 27AF43 27 inch television that no longer powers on at all. We had a lightning strike right next to our house and it tripped our breaker box. When I flipped it back on all other electronics...


Lightening does a LOT of damage, I wouldn`t have it repaired and I`d contact my house insurance immediately. I`ve repaired lightening damaged sets before only to find that the set only lasts a short period before different fault appears and once you make a claim on the insurance for a repair, they won`t pay out again for another repair on the same set. The problem you`ve got is when the lightening hit the power line, it sent a transient or high voltage pulse through your power lines. The computer and a lot of the other circuits in your set only run at about 5 volts. If your TV power is normally 240 volts like ours is and the transient pulse rises 1,000%, (In practice a lot higher than this) in effect the power lines in your home will have risen momentarily to 2,640 volts. This means that the other voltages in the set will have risen proportionally with the input voltage meaning that the 5 volt lines will have risen to 55 volts which would either destroy the circuits on that line or as you will find out later if you have the set repaired, weaken the circuits which may survive for a short period until you`re sat down watching your favorite TV program and one of these components decide to give up. Take my advice and claim for a replacement set, You`ve been warned. Ian

We had a near lightning strike and now my tv (sanyo model ht27744)doesn't want to come on.


Lightening may have caused a surge on your power lines to the house and to the outlet the TV was on.
Do other things work on that outlet? If not you tripped a power breaker.If they do work check this.
Unplug the TV for 2 min or more and plug back in.
Try bypassing your surge protector you had it plugged into. It could have died when the lightening struck.
(no surge protector?) Bet you'll buy one for your next TV.
Look for 3000 joules and up rating for a surge protector and insure it has protection for a cable/antenna input too.
If this doesn't work the TV may be fried or internal fuse blown.
Time to take it to a repair shop or depending on it's age (5 years+) it may be time to buy a new TV and surge protector.
Near Lightening strikes can effect appliances from several inputs that could be affected from outside like Power, Cable, Antennas, Phone Lines that come into your house.

Sony, tv comes on color fine, then turns red


I had the same problem with my TV, but the hue was blue. I was told that not only did I have to replace the picture tube that wasn't staying on, but I would have to replace them all because they would not mix properly. After much investigation, I found that there is an adjustment for a variable power supply to each tube that can brighten and lighten each tube. I adjusted the RED pot and my picture color issue was resolved! To access this adjustment you must remove the front panel on the TV. At the bottom corners there are two small screw covers that you must remove. Then un-screw the screws under the covers. Then pull the front panel off of the TV, (it hooks under the top near the screen so it will swing out from the bottom). Now remove the wooden panel in the center, (four screws). The pot adjustments are at the bottom of the TV. They are marked for Red, Blue, and Green. They are extremely sensitive, don't turn them much! If you over adjust you will get red, green, or blue lines on your screen. Adjust back down to remove these, (this is also the remedy for removing these lines that can appear over time). Good Luck and God Bless!
