    I need power supply

    I unplugged and moved the tv to another location in the room, and now it appears to have no power.

    I have the same problem. The on switch is normally lit but now there is nothing. The earlier poster seem to indicate that the problem is the power switch. If they are correct then I'll need to have this switch replaced and I need information on someone who does this in the Washington DC area or who has some way for me to ship them this monitor. I have NO packing supplies.
    I don't know if it is resonable to have this repaired.

    the TV is plugged in properly there is electricity the power cord if working the TV does not run.

    It may be the powerboard. My friend has a Panasonic TH-42PX75U with the same problem. Watching it and all of a sudden, it shut down. No light on the power switch - completely dead. Checked the power supply cord with meter - has power. Took the back off it and found a blown fuse - replaced it, plugged it back in and it immediately blew again. I think we have isolated the problem to the powerboard - Has anyone heard of faulty resisters or something in the board that needs to be replaced? I dont want to spend 3 or $400 when I can buy the same TV (brand new) for 699. Anyone else traced it down this far and have you found a powerboard? According to this site, it looks like it happens quite a bit.

    Same problem is this worth even getting fixed...Three weeks old

  • Anonymous Mar 13, 2009

    I had the same experience and problem with a 4-year old Sony KLV-32M1. It was on and worked perfectly. Then all of a sudden - poof - no red/green light - nothing. Does anyone know how much this might cost to fix? Sounds like all the replaced fuses did not help. Thanks.

I had this issue, I tore the tv apart and found that my power switch had gone bad. I just traced the power using a multimeter. There was no fuse it the power line, and no reset button that I noticed.

No audio, no video


Most likely the power supply. In most models, if the lamp goes out you will still get sound. However, the power supply is not a single piece swap. I would suggest getting a voltmeter, and check the voltage where the power cord meets the power supply. Then follow the circuit pathways, checking after each component, until you find a break in power. You are getting power to that light, so some power is getting through. However, the light works on much less voltage than the rest of the television, so probably there is a capacitor or transformer that's gone out.

My Sylvania 32" Tv Model #SRT2232S won't turn


Hello
There is a fuse inside the power supply bard of your sylvania TV. Check whether it has blown out. If bllown out, replace it with same type bothe in size and amperage. If the newly inserted fuse also blow up as soon as you switch on the set, make sure that the power supply section has some short circuit in it, and should be cheked well. OK.

I have a 32" CRT Sylvania Tv that won't turn


Hello
If the TV doesn't turn ON ata all, it is surely due to some fault with its power supply regulator section. You haven't given any otehr details of your tV, than it is only a 32 inch CRT Sylvanial Tv. No model number; so I only can provide you a solution in general.
Check the ON-OFF switch for its contact. Normally, TVs uses DPST type switches [Double Pole Single Throw]. If any one contact amoung them have any problem with its internal contacts, the set won't switch ON. If the switch is OK, come towards the power regulator section circuit board, and check whether the fuse has blown out or not. If it has blown out, replace it with same type and ampere rating. Never use higher ampere rating than specified. The ampere rating will be maiked either on the rims of the fuse, or at the printed circuit board, just under the fuse. After repalcing the fuse, switch ON the TV and see whether it works well or the replaced fuse blows up as soon as you switch ON the set. If the repalced switch burns out as soon as you switch ON the set, the power supply section has damaged [shorted components in it]; and should be replaced.
Normally for LCD TVs it will be good to replace the power supply as card basis. This power regulator card can be bought from most of the electronic spare part shops at your town, orby the authorised service center for Sylvania at your town. If you may have given its model number, I could send you the picture of the power card of your TV. OK.

Philips 47PFL7422 Flat Screen no power


Check the main fuse
If that is ok look for puffed up capacitors on the power supply
Check the 1000ufd @ 35v change them to 1000uf @ 50volts

Good luck

LCD TV WONT POWER ON


A dead condition usually indicates one of the following: Open fuse (often internal, and usually pops due to other circuit defects). Short (overload condition) in the circuitry. Failure elsewhere in the circuitry. Most modern electronics have some logic circuitry, and if there is a section of the circuit not working, the logic circuit keeps the set from coming on at all.

First, if your power cord plugs into the set, check that it is properly connected. If you can get into the internals, find the fuse, check it, replace with an exact or near exact size.

If problems are beyond the simple, technical expertise will be required to nail down and fix the problem.

Fuse Blowing


A blown fuse is usually caused by a shorted regulator or a bridge rectifier circuit. Either way it is a problem in the primary power supply. A bad cord won't blow the fuse in the set, it will blow a circuit breaker in the house. A servicer usually would normally cover the inside of the set with a "few light slits in the AC cord". Hope this helps
