Magnavox has issues with puffed caps on the power supply. This sounds like its a 32 inch lcd tv. I tried searching for a service manual for this and can't find one. If it is an lcd you need to look at the capacitors on the power supply. If they are puffed up, you will need to replace them with equal or slightly larger valued capacitors. The capacitor values are mfd and voltage printed on the capacitors themselves. You will need a soldering iron to replace them. Lay the tv, if it is an lcd, on a flat surface cushioned by a blanket. Make sure the surface is large enough to support the tv frame, as you don't want to cause damage to the panel. remove the back of the tv. There are numerous screws, and once the back is off, check the power supply pcb for puffed caps. This is the board with the power cord attached. I know in magnavox tv there is a cage covering the power supply, so remove any connectors because you will have to flip the cage housing the power supply to get to the caps. If you feel confident, give it a try. Let me know how it goes

Am I diagnosing the problem correctly?


Sounds like a bad component in the power supply. Most likely a bad capacitor.

My Magnavox plasma screen tv, model number: 42MF237S/37 makes a clicking sound when I try to turn it on. No sounds, no picture, just the clicking noise. Things I have tried so far: 1) Turning the TV off...


You either have a cold solder joint in your horizontal deflection circuits or your or in your horizontal output circuit. please be careful due to the fly-back transformer still holds power even unplugged until you discharge it.( ground it out). Hope this helps.

Tv will not turn on


A: Is there a humming sound coming from the TV set?
Check the brightness/contrast. If nothing still, remove power to the set for 24 hrs. and reconnect and retry. If it's not coming back up, the PCB ("motherboard") for the set has most likely died. Check for warranty information in your user's manual for further instructions.

B: Is the TV sharing an electrical line with a wall switch?
Remove the set from that circuit and try another outlet. If not, follow the Steps for "A".

C: Was it during a power storm, when it went blank?
Check the outlet with another appliance - if that device works, try the Steps in "A".

sounds like somthing may have gotten knoked loose in transportation. I'd check all the interneal connections, make sure its unpluged for a few hrs or a day before sticking unexperienced hands in there. there are some high voltage capcators in it. stay away from fat red wires the size of TV cable.

also call the people you got it from make sure they know your not holding them responsible and ask if they fixed anything recently or in the past espically the IC convergence chip and resisitors, usally those go on these sets.

Great reference link that I posted pictures on, check out page 3

TV turns off/on by itself


thats why you got this TV for free I'm afraid. Your problem will cost more then the set is worth to have it repaired. Unless you understand how the differant circuits work, and know how to read a schematic, follow the circuit flow, and use a multimeter, this will not be an easy fix for you to do. There are components in the power supply that need to be replaced. Good Luck

Powers off by itself.


Power supply or sweep suppys have parts that are overheating and breaking down or cold solder connections. Call someone who knows this set like the local authorized magnavox/Phillips dealer/servicer. Good Luck

I'm hoping to get some clarification as to whether the below is correct or whether I have been taken for a ride. My LG was picked up by a repair service because it started displaying horizonal lines with the picture hazily in the background. I undertook some research and learned that in most cases of the boards needed replacing and it wasn't a panel issue (usually panel issues are associated with vertical lines). After having my TV for 5 days the repair service advised that it required a new power board and a small repair required on another board. They repaired the small repair and I was going to purchase a new power board however the TV has been returned to me dead. It now doesn't even turn on. The power/channel/indicator lights at the bottom flash on then switch off automatically. After getting consumer affairs involved, I finally received a call from the sub contractor and aside from a number of different excuses given based on my questioning of each explanation, all were contrary to the initial diagnosis discussed with me in early June. I documented the conversation which I summarise as follows: - he contacted numerous times however I never received any voicemail. I asked why - after "numerous phone calls" he didn't send a txt msg to which he replied that he's not allowed to send messages. - he initially alleged that the power board was repaired and video board needed replacing which I was quoted for. I corrected him advising that I was told and quoted for a new power board ($530) and the video board was to be repaired. He then changed his story agreeing with me and alleged that found and apparently quoted me $445 for a generic power board but I declined....Just to clarify, I never received this 2nd quote which is evidenced within the emails and messages I sent after receiving no response over a number of weeks. - he continued to claim that the TV now has panel problems and is now not repairable. - I recited the discussion the owner had with me which was consistent with the information when he provided me with the original quote of $530. He then altered his story replying that "this is a rare case... The owner doesn't know what he's saying". - When I challenged why I was quoted for a power board when he is now claiming there are panel issues, his response was that a new power board was to test if the panel was cracked!! - I replied saying that the TV was delivered to them with horizontal lines and even after testing should've been returned with horizonal lines however is now dead. - his excuse changed again advising that during testing he short circuited the TV and replacing the power board would continue to short circuit the video board..When I again questioned WHY then was i quoted for a new power board (as per the owners conversation with me) he returned back to stating that it was a rare case! - I told him about the screws missing in the back panel to which he commented that "they" wouldn't have put them back in because "they" assumed I would just dispose of the TV. What I find interesting is that this was his understanding whilst I was led to believe the TV was repaired (pending a new power board). It now makes sense as to why the driver who delivered the TV literally dropped it off and ran advising that he didn't know anything. I never received a service report and asked for it again however am yet to see it. Based on this information, can anybody shed light on what they've done to the TV? Prior to them taking the TV the horizontal lines were consistent with had a faint picture in the background and didn't alter at all. They're claiming that they did nothing and the TV - claiming that the reason why the panel doesn't turn on is because it was kept on while they were testing.
