1 Answer

I have a Philips Plasma tv 42pf5321d/37 with sound but no picture

The other night while watching the tv there was a very load pop and the picture and sound went out and the LED on the front started blinking red. I unplugged the tv waited 10 minutes and then plugged it in again. The TV worked I had sound and a picture again, but after 15 minutes there was another very load pop again and the picture and sound were gove again and LED was blinking red. I unplugged it again and then plugged it back in the next morning and now I have sound, but no picture and the LED is green. Any suggestions would be greatly appreciated

Thats the great sound of Exploding capacitors on either the power supply board. or another one in there. Now the set is in fault protection. It tried to warn you with the RED blinking LED that there was something amiss by shutting itself down. When you unplugged you reset the error and allowed it to do it again.

Best Regards and Smper Fi

SOURCE: plasma tv in protect mode

Hi,

One of the PCB's inside has an incorrect voltage/short or dry joint, all TV now days have a diagnostic startup mode which checks all the boards, one of yours threw up a problem so the TV put itself into Protect Mode so that it doesn't do anymore damage.

Get it checked out by an engineer.

Thanks

Most likely a power supply problem. If it's covered under the warranty take it in right away and have them fix it. If not a good Philip's service shop can fix it. They may have a flat fee repair charge?

4 blinks is an error on the I2C bus 3 - the one that holds VIPER (the protection system), Stand-by Processor, and NVM. Since this is triggered by the processor when the NVM can't contact the Viper or it's not powered (the 12 volts line to it is missing) the digital board was operational and it was changed for nothing.
Most likely the defect is in the power source and you will have to replace it. To help you use this service manual for a very similar unit

PHILLIPS PLASMA TV MODEL #42PF9431D/37 Heard


Hi, Usually any "Pops" are an Electrolytic Capacitor "blowing up" quite literally, or "Gassing" as it is called. This happens due to some sort of power problem. Capacitors hate AC Voltage and Current, and Heat and Over Voltage. All of which, I have no doubt it was exposed to before it went "Pop" This is only a symptom of a far greater problem, to come, no doubt, soon, the rest of the set will fail too. Please DO NOT USE. this set any more, you risk fire or explosion or both. If you MUST use it at least unplug at bed time. Theses days home repair except for the most rudimentary problem is not feasible, setting aside the safety aspect. In my professional opinion, I would recommend, that you get a "Quote" for repair from a Philips Authorised Service Agent This is very important, that you contact a Philips head office and ask for a referral. This way at least you can make a decision to repair or replace.
