Wy dose the tv always make noise like some is poping inside it


popping inside electronics usually means it's power supply internally may be going bad.

Some units have "switching power supplies" and you might hear a very light click when it switches. Loud pops or frequent louder clicks are a bad sign.

Lecy blew tv wouldn't come back on change fuse in plug still no light on tv does 42" lg hd tv have a fuse internal.


Yes, TV's have an internal fuse on the power supply. All too often though more damage is caused besides a blown fuse or the fuse doesn't serve the purpose and the power supply is damaged. You can check and replace the fuse as necessary. If you need a replacement power supply, here is a list of vendors below. Have your TV model ready to help you find the part you need.

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.

hi....hope this can help...
try to check the power cord, see if there's a cut or open wire...
there's a possibility a open or no continuity of wires from plug to the power supply due to frequent bending of wires.. so no AC voltage goes through the wire..
second check for an internal fuse..if it has a open wire (hair like) inside it is visible inside the glass tube...if it is open or has light discoloration..replace fuse w/ same type/ value...if it is extreme dark discoloration you may have a shorted bridge type rectifier or power MOSFET...i suggest that if you have replace the fuse and tested the unit and still blown the fuse...do not attempt to replace fuse and test the unit..it may cause further damage to the TV..ask assistance for repairing the power supply, it is repairable than to purchase a new power supply and gonna cost you less...good day... please rate and vote...

Bought a 26 inch proscan from Costco on line. Tv won't turn on, led light is off as well. own TV approx 2 years wah can i do besides leave TV curbside?


Hi sglassgold,

Here are steps that may help you fixing the problem. You should prepare tools and multimeter.

I'm assuming that your unit is dead set and your outlet is live.1.Power cord - check the cord it might be opened (no continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse- sometimes the fuse fail because of the power surge, replacing with new one will cure the problem, If this is the case I've advice you to use surge protector/AVR (Automatic Voltage Regulator). However if the fuse blew again this is an indication that you have a shorted parts on the power supply, you may visit the linkhttp://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and still the unit didn't power up then you have an open parts on the power supply.

4.If you see that the fuse is intact on the board, don't attempt to touch anything because there somefatal components stored electricity enough to hurt you with a simple mistake only.

The next steps should be done by an expert or qualified technician because isolating the problem on the power supply is technical and complicated. I would advice also to replace the entire power supply for your convenience if finding technician there is not possible.

Also check if your unit is under warranty before opening the back panel, it will void the warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.



Hope I helped you.



Have a nice day!



Thanks for using Fixya.

The TV wont come on at all, the power source is good The model # is DP19648 Sanyo Is there a reset button on TV?


d cooper, Because your unit is small screen type, You should visit YOUTUBE and view video clips of cold cathode fluorescent lamp back-lit lcd computer monitors being repaired. Your unit is subject to the same type of internal "switch-mode-power-supply/CCFL inverter ballast" circuit problems as are lcd monitors. Search terms at youtube are: "lcd monitor disassembly" and "lcd monitor repair" Then look for and view lcd tv repair video clips. Inspect your unit for "bad" (failed) electrolytic filter capacitors on the AC to DC switch mode multiple output power supply board. May have "open" fuse inside near or on the smps board. If "open fuse" the next question is why??? 12fixlouie

TV will not power on. Check supply to set and it is fine. Tried remote and local power switch. Is there an internal reset? The unit is a LG 37 inch LCD approx. 1.5 years old.


There is not an internal reset for this. You would need to check what voltages you are getting from the secondary side of the power supply, this would then indicate if the problem is with the main board not starting up the system or if the power supply has a fault. If you have a multimeter then you can carefully check for 24v 5v & 12v supplies. If you are not getting any voltages then the primary side of the power supply may be at fault. The first thing to check would be the fuse at the incoming mains supply on the power board, if this has blown then suspect one of the senmi-conductors & check to see if any of the capacitors are swoolen if so replace them.
