Tv wont start

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.

LCD TV Repair No Power Power Supply Common Symptoms Solutions How to...

fried it, unfixable, get a new one. and start unplugging everything during storms. if you still want to watch tv while there is storm get a old crappy small tv to watch while you high priced one is in safe position(unplugged)

I will need the model number of the set in order to assist with the problem.

Hello,

Its the problem of overheating in the power supply board of the TV.on the power supply board of the TV there are few capacitors and IC.any of this ic is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.
Hope this help in solving the problem, Take care.....

Hello, This is a sudden high voltage, it will require opening the television to check faulty component. First check for fuses in the printed circuit board and if found replace with same current rating. Also check other component such as the power transistor, resistor, rectifier with a multimeter set at ohms range

you need to remove main ckt, (m.board) some part need to re solder specially in hot area. (lost contact i one of the flickering problem you encountered.

you'll probably find the power supply of the lcd is broken. try getting a new powersupply and try to work it then

I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

replace tuner borads.

Yes, it's quite possible that you indeed may have sufferd from a Power Spike, induced by lightning during the storm, esspecially if plugged in during said storm. I have had quite a few customers ova the years with this exact problem. I always advise my clients to unplug ALL devices during a storm, and for ones that simply cannot be unplugged then some sort of Spike/Surge Protection device MUST be used. As a matter of interest, I have written many a report to insurance companies to support a claim for a replacement.
