Hello. The first problem with this tv was that the picture started to leave the tube and move up and down rapidly. I took the tv case off and left it off on an outlet outside, appeared to have burning smell. A friend of mind told me that the vertical had to be re soldered. So i touched it with a screwdriver and it appered to bring the picture back so it was soldered. next i saw the sound was not clear through the the left speaker so i soldered the audio cheap and eventually the tv died. Took it to my friend he replaced a burnt resistor and a chip on the power supply and also the horizontal. TV works at the beginning , but pictures cuts off and sound remains. Tried another power supply and same thing. This happened with many tries and eventually it burned the same components again (horizontal, and a resistor and some other chip from the power supply). Any advice on what might be wrong? Thanks for the help

This model TV has a gasket on the red picture tube that faces down. The coolant leaks from between the picture tube and the lense assembly. When this happens the red tube over heats and shorts out internally and usually cracks the glass.You will probably find coolant all over the circuit board if you open the back panel of the TV.
Call a good TV Tech to repair this. It will cost over $500 if the picture tube is still available.
picture tubes do not "blow" go bad by going dark check your circuit board for fuses test them and, replace the bad ones as your high voltage circuit is what lights up your tv tube... tv tubes do go bad when they do they show "blooming" and, bad ion masking not a black screen unless the tv is a newer lcd / plasma screen then just replace the inverter board or, cold cathode
Hello there, I'm having a major problem with my TV, I have called all
of the local TV repair shops and they all are the same, they want money
money money before they will even speak with me about the problem I'm
having. This is the only TV in my entire household for a family of 4
and we desperately need the TV in working condition for our kids. I
don't want to have to put out $500 for another set if I don't
absolutely have to.
About 3-4 months ago the TV when turned on, the picture would slowly
come into view and be very scrambled and before the picture would come
into complete view the TV power would shut itself off, but the power
light would remain on. You can hear the "Click" noise when it would
shut itself off.
2-3 seconds after it 'shut itself off' then the TV would make the
"Click" noise (The same noise it makes when you first turn it on), it
would make the "Click" noise over and over and over again but nothing
would happen. So i would turn it off and on again and change the
channel rapidly until after 2-3 minutes it would come into view and
So we decided to leave the TV on 24 hours a day. Then today we awoke
and it was off and making the "clicking" noise over and over and over
again but with no picture or sound. Now it wont even turn on/off it
just sits there and goes "Click, Click Click Click" and doesn't do
I described the problem as best as I can. Here is the TV information and specifications...
Philips 27 Inch Tube TV
Model Number... 27PT54 3S37A
Serial Number... 78438404
Date Code March 2003
Now that I typed the model number there are threads everywhere people
saying the same issue exactly as me, I will read them but please
someone tell me is there anything I can do...
Can anyone explain exactly what is wrong with the Tv and why it's doing this?
Also, what should I expect to pay to repair it?
Any information or help would be appreciated very much.
Thanks in advance,
Just got off the phone with certified Philips shop...they said they
will repair it for $100-$130 with a $25 down payment just drop it off
and he will call me when its done. Does this sound like its worth it or
a rip off?
You more than likely have a cold solder joint, and moving the tv caused the hair line joint to crack open just enough to prevent current from flowing. But before you start soldering, give it a good inspection inside for a loose connector and/or wire. If no luck, take a solder gun and lightly hit the largest joints first, which are part of the largest component on the circuit board. It has a thick red wire coming out of it that goes to the tube. (Do NOT touch this red wire or disconnect it from the tube. It can still shock you, EVEN WITH THE TV OFF. This is a very high voltage with low current and probabliy will not kill you, but it will hurt very badly, so just be careful and stay away from the big red wire coming out of the tube.) Then resolder all the larger chips, transistors, and capacitors. If still no luck, then resolder the hundreds of smaller joints.
First it's not just Philips, they all are making TV to only last a few years now, they are not made to last, thats how they make money by selling you something you will have to replace in just a few short years. As far as your problem, you may have a cold solder joint somewhere, do you have a 25/35 watt soldering iron? if so try soldering pins on the regulator IC the vertical IC the horz output transistor and drive transformer and the flyback, in fact solder just about as much as you can, spend some time in there soldering. Dont forget to ubplug the set and stay away from the high voltage anode connected to the picture tube, it can still hold a charge even if the set is unplugged, do not try to take it off. Hope this helps!
A very good chance this tv was dropped or bumped. Sounds like the internal plastic frame is broken and will not support the picture tube. Find someone with tv experience to fix this. I would suggest they use a putty found at an auto parts store. To glue the tube and the frame together. This putty is in a plastic tube. You tear off a piece and fold it several times to activate. It will surely do the job.
It seems you might have cold solder connections on the picture tube socket or on the picture tube drive board. If your not a tech please call someone to assist you with repair as you can be seriously hurt by the HI voltage insiode this set an or cauae more problems with the set. Good Luck
