just hook an antenna, find "auto program channels" in menu.

Hello,

Your power supply board is not yet dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.


Hope this help

The TV needs to be connected to its tuner box in order for it to fire up properly. In fact, with the TV in standby (red light), by switching on the tuner box a control signal is sent up the cable and the TV switches on fully.

Most of the reported symptoms like these are power supply related and not usually an expensive repair.. If you're doing this yourself take a look at the power supply board - you'll have to remove it - check the cap at 2662 for any signs of buldging. If you have an ESR meter measure it's equivilent series resistance and replace if necessary. Next look closely at the board for ring cracks of the various solder joints. Pay close attention to the diodes at 6041 and 6046. part of the bridge system. Any ring cracks found flow some solder across them to make good contact then re-install the power supple and try to power the unit.

U HAVE 2 BAD CAPACITOR ON POWER SUPPLY 3300UF AT 16 OR 10 VOLTS

Does no picture imply that you have sound? Or it just turns on with no picture and no sound? Please clarify this info so that I can help you resolve you problem. It sounds like a audio/video mainboard issue. Just want to be sure.

Check for bulged electrolytic capacitors in the power supply.

I would certainly say the problem is in your power supply. Chances are real good that two capacitors are bad! You will have to remove the back cover...this is tedious and requires patience. You will be concerned with the board on the left side. You will have to remove the screws on the power board to lift it and see the top of this board. You should see at least one bulged capacitor. Replace, and you can bet the other next to it is bad. And another note..there may be a small cap at about 16volts at 10Mf that needs attention. These are clues and should help with repairs! Thanks for asking.

Are all the caps good on the PSB.? Most sets have Samy boards and they used very shotty capacitors. Some show NO visual clues of being blown as in poped at the (X) top. They just vaporize/dry out. Do you have a cap tester?


Best Regards and Semper Fi

Failing capacitors in the power supply have now failed completely.

Had never tried blow-drier as a TV service tool.

Heat changes the resistance of many parts, especially dying capacitors. Heat also causes parts to expand, such that cracked solder connections are closed up.

your tv has bad power supply. Repair it or replace.

the lines are most likely the panel which isnt cheap
the blue speckles are just a voltage adj. on the y sistain if you feel confident enough you could try this yourself(though expensive equipment is usually required i do without). what you would have to do is take off the back panel if you have a stand put it back on that. easier to work on. then plug it. BE CAREFUL not to touch anything inside!!! from the back you will see a board on the left side on that board will be a small board attached vertically it will have a gray screw attached(very small). with the tv on you adj. the screw until the blue goes away(a little does alot).

Here's a thread that you might be interested in.

My first response would have been 'No, of course not!"

After having come across these and similar posts, I do find some arguments possible - especially the points about those screens that had been mounted or 'hung' in such a way that there was an uneven or twisting pressure or torsion on the screen.

Having mistakenly shattered a car's windshield myself by applying too much pressure to a corner of it with a screwdriver, I can even buy the idea of a screen clamp being set too tight during manufacture.

Is it 'more likely' the screen was hit by a ball? I would suggest that more TV's are damaged by (embarrassed) people than are cracked by improper installation or manufacture. But apparently, the less likely scenario can and does happen.

I hope that helps.

you have a problem in the power supply module more then likely their a caps blown they will be obvious tops blown off or busted open youll have to take back off look on module in the middle

Check all the capaciotors in the power supply board for bulges up or little puffs up.Change these capacitors will get ur power back to normal funsctions.

check this, http://www.fixya.com/Brands/Manuals/P/Philips/32fd9954_32_366398ce8365a807148fb6347e533a3f/images/D8D92726D516F1C8C8FA11404B2B0E53.png

that could be a sign of a bad panel. my experience is that these panels are more expensive than the tv itself, but might be worth looking into since I've heard about prices coming down
