How many blinks do you get ???? It put itself in protect mode so the TV thinks something is wrong.

2 blinks X sus circuit board temp is too high

3 blinks y sus circuit board temp is too high

4 blinks center temp is too high

5 blinks digital 5V circuit is messed up

6 blinks means the PDP Panel board has failed

If you feel you cannot fix it or its too much money I will buy the TV off you for a part that I need for my sony pfm-42b Please email me at [email protected] and we can discuss this in more detail

you got to go into more detail in order for you to get help..but if you are saying only red light comes on plug out the tv from the current outlet then plug it back after an hour.... if your tv does not come on then you will need to take it to a tech so it can be repaired.since there is no blinks from your tv thats means the following components should be checked..this is in the stand by power section resistor R 607 tran Q601 ic601 R612 AND VDR 601...CHECK ALL THE FUSS.good luck.

Use and HDMI cable if your tv supports it. This Cable is convienent and will provide the best audio and video quality. They range greatly in price. You can get a good $20 cable at any major retailer.

I had a similar problem with my 42 in Philips LCD HDTV. Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired ofcourse) and found four bulged capacitors on the PSB. Many major electronics companiesPhilips/Magnavox, Sony, Panasonic, and others were sold capacitors that failedin 2-5 years instead of 10-20. Thecapacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in allsorts of devices and cause a wide range of failure problems. Here are some options for you. 1. Have it fixed by a professional $$$$$$$??????? (Is itunder warranty?) Remember, TVs CONTAINHIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk. 2. Open your TV and find PSB. (The board that the power cordplugs into) Check for faulty caps. If you find some (bulged or leaking) bad capsreplace the entire board. The entireboard costs around $250 right now because they are in high demand right now.They can be found online. I woulddefinitely shop around though. 3. Remove and then replace individual faulty caps. This takes some soldering skill. Caps are inexpensive and if you can take care of it yourselfit will save you hundreds. This may be your problem. If you determine that it might be. I have a Tip/How TO tutorialon this site that may also help. Itgives step by step instructions for replacing caps on PSB #715t2432-2. If this isyour board you are in luck. Here is theLink: Fixingthe Philips Turns/shuts off on its own problem. I'm working on uploading pictures to helpguide people though the process as well. Let me know if I can do anything to help. Hope this helps and if it does please rate itaccordingly. Good luck.Kaufman605

It is possible that the TV was hit by a small power surge, and the audio processor is locked up. You need to unplug the TV from the wall for 40 MIN, and that will reset the audio processor back to normal.

Unfortunately the news I have is not good. 6 flashes is a panel error, meaning that either you have a bad panel or a fault in one of the drive boards for the panel. Unfortunately, it will take a technician to verify which of the two is at fault. In my personal experience with this set, it usually the plasma panel which has failed when this error occurs. The cost of the panel is over $1000, which usually means it is cheaper to replace the set than repair it. I wish I had better news for you.

Let me know,if needed further assistance.

Hope i helped you.

Detection of at the left side of panel temperature (Name of this function on the service menu : TEMPERATURE-PANEL SIDE)

Occurrence of abnormality and fault is judged solely from the internal temperature of the PFM-42B1/B1E. Measurement of the ambient temperature aims mainly at confirmation of the operating environment. Therefore, there is no chance to indicate this warning message.
Warning of high temperature at 85C or higher.

The fault is (at
least) blown chips on the SDMD and SDMU flat cable assemblies which
connect (and drive) the plasma display. These are located under the two
metal covers on the left edge of the plasma display - both plug into
the YSUS board.It has to be taken care by SONY.

In Most Countries especially Australia , Sony is Repairing this Without Any Charge. There is NO RECALL. It depends on How you Present this Problem to them. This is a COMMON problem on this Model.

Let me know, if needed further assistance.

Hope i helped you.

you should change it from hdmi to cable. You can do it only on a hdmi tv when you do that you can use it for the pfm-42b1e because i had the same problem too. when you plug your ps3 to a hdmi tv you go to settings-display settings- video output settings than you change it to av multi. After you do that you can use it on pfm-42b1e
