When playing, the picture completely disapears while the sound remains. The picture may come back by itself when I switch the TV off and turn it on after few hours. Sometimes when I turn on the TV the picture won't come, but it will come suddently after waiting for few minutes.

Check and make sure your fans are working and there is sufficiant cooling to the back of the set. Sounds like it is overheating and going into protection mode.

Sounds like you have some bad capacitors on your power supply. If you are good with a soldering iron, this is a simple fix. There is a group of either 1000mf/10v or 2200mf/10v. they will be easy to spot out, because they will be swollen, rounded on the top. Replace them and you should be good to go. If this is something you are not comfortable doing, then I would take it to a authorized service center. You would mostly just pay for labor, as the parts are only a couple of dollars.

To get the right colors, especially a plain white, requires the right mix of red, green and blue from the picture tube. Sony TV sets have a circuit called AKB that automatically keeps the picture tube balanced by adjusting the signals to it. If that balance can't be achieved it shuts off the picture. This may due to tube aging so one of the color guns is too weak to adjust, or failure of parts in the AKB circuit itself. If the sound stays on and the power light starts blinking when the picture goes off, this is likely why.

On the other hand, if the set is turning off completely with no picture, sound or power light, the set may have power supply problems or defective parts in the picture tube high voltage circuits.

Since there are several possible causes, this set needs to be checked by a technician who can diagnose the problem and decide what needs to be done. It's not a simple thing I can point to and say "change this part". If the picture tube is the cause, it's better to replace the set. Otherwise get an estimate, then decide whether to fix or replace.

Okay this sounds like you have two blown capacitors on the signal board

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.

The Problem...

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 work.

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 anything.

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

105 Watts
60HZ
120V
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,
Anthony



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?

Hi this is Matt, some units have fans in the back, if you can open it and look in the back, also make sure its free of dust in the back, this can be from overheating, also bad solder joints on the power to the lights in the screen, can be this, you may need to replace the board, feel free to get back to me

I had a similar problem where my 61" Samsung DLP was turning itself off very frequently I had resolved to try replacing the bulb. I called a local TV repair place to see if they had my buld in stock. The guy I spoke to actually told me how to fix my problem! There is a little blue switch behind the bulb access door. The inside of the door has a little piece that presses the switch down. The switch is supposed to work correctly weather the switch is in the up or down position but samsung forgot to take expansion from heat into account. If the switch is held in the upper position by the door and the plastic expands to a certain point, it triggers the set to shut off. This does not occur of the switch is held in the lower position. What you need to do is take the access door off and put it back on by sliding it into position from above. That will hold the switch in the down position, eliminating the problem. My set has not **** itself off ever since.

new bulbs can leak on your pc board if not installed correctly and the fluid starts to short things out... triggers the error message.


remember always check the last thing you did before having problems.

Do you have a VCR or DVD recorder? If yes, set it to record what you are watching. After a "blackout" rewind the tape and review it. If there is a blackout on the tape, the problem is the sallite box, if not, it is the TV! QED
