Hi, i bought a LCD TV of philips model 42PFL3605/98 AND SERIAL NO. SR1A1135000340 . The tv is not turning on. i have had this problem three times. the first two times i called the technicians from the shop from where i bought it as it was on guarantee. now it is not turning on again. apparently for the first two times it was a software problem they had to upgrade it. Is there a way i can fix it myself i.e upgrade it or reinstall the software on the tv? please help

SOURCE: Philips LCD model 26TA1000, vertical lines and blank white screen with no picture

it would be easier to find it stripped from a damaged set on ebay.
I see several there but need the part number to search
of course you may purchase that and find it to be the lcd driver.hopefully not.

Sounds like a temperature problem if it takes a while for the problem to happen there are several things u can try and figure it out yourself. 1. Remove the back cover of the tv and turn the tv on. 2. use a hair dryer and apply heat to various boards of the lcd (inverters, power supply and scaler) while applying heat to see what board reacts and makes the tv go dark. More than likely its a defective LCD panel and its just as easy to send it back and get a replacement TV.

I had the same problem with a philips 42FD9932 and fixed with a great online tutorial. Just replace 3 capacitors available at Radioshack onthe the board. 2662, 2663, 2664 1 is a 1000uf the others are 100uf. Max Volts need to be over 25. It worked great, check http://dynamicorange.com/2008/06/25/fixing-a-plasma-tv/

SOURCE: My Philips 32PFL5403D LCD TV does not turn on and blinks 6

Normally, this happens when the TV detects a bad circuit board and goes into " Protection Mode ". The blinking red light should be a error trouble code. I don't have the Service Manual on hand for your model number to tell you what the code means. Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

Philips 32" tv will not turn on flashing three


hi,
You have to check the power supply of you tv for any voltage missing. also check the back light inverter board for any short circuit in it. Inverter transformers in the back light controlling board can become faulty.Three blink indicate the power supply have some problem. First of all replace all the electrolytic capacitors in the power supply board. If filter capacitors in the power supply is bad then this problem can occur.
ok

Hi. I have a 42"


The best solution to this problem is to call Toshiba directly and ask for assistance. Any TV repair company/shop will probably charge you an automatic fee to assess the problem, and then tell you it's a very expensive fix. With just the model and serial number of your TV, an easy 5 minutes will get you the answer you are looking for.

Volume in the tv is not working, and you turn the tv on or off it comes three to four minutes later. The tv was bought nine months ago, it's an LCD 42 inches MODEL #42MF439B/F7


If it is nine months old the set must still be under warranty, the problem you are describing is an intermittent audio problem and can be difficult to locate. I recommend getting in touch with the people you bought it from and get the satisfaction you deserve.

Place electrical tape over the IR port. If the problem continues, replace the TV. If the electrical tape helps, then there is someone near you, having fun at your expense.

Philips flat screen TV MODEL ID 19PFL5422D/27


I bought the television less than a year ago, so I called Philips Magnavox and they asked for the serial and model numbers. Next thing I know they asked for my name and address and Philips is sending a brand new television to replace it !!! The new one should arrive in about ten days. How's that for service? I'm very happy that I bought Philips and I will do so again. So don't forget to keep all the paper work that comes with your new televisions,especially Model and Serial numbers ! Thanks for asking , Debbie Hoffman
