Re: philips 15mf050v

This model of television seems to have a thermal problem (design issue) where IC U14 gets too hot and shuts down. It can be fixed, but it requires opening the set and soldering. What needs to be done is to add a diode (3 Amp, any Voltage) in series with Coil L18. This fixed 2 sets that I have. Adding heat-sinking alone didn't work. You can confirm this problem by running the set somewhere cold and noting that it takes much longer to shutdown or doesn't shutdown at all.

Re: philips 15mf050v

No,it sounds like a power board failure,look for swollen capacitors,check diodes,and transistors with a multimeter,transistors that read 0 are considered shorted,research them before you just dive into this set though.

I would also keep in mind the small signal board,that may cause it to shut off as well if there's too much current going where it shouldnt be going as a circuit protection

My Sharp LC-42SB45U takes 15 min to an hour to turn on. Also, sometimes picture blacks out for 10-15 seconds. Any suggestions? Pat Courson

Have same problem. Not the proper fix though I found that taking the back off and heating it up with a heat gun for 30 seconds to 1 minute and tv works fine till you shut it off over night.Maybe someone can offer a solution with that in mind. Pretty strange

This is most certainly a capacitor in the power supply that has gone low in value, hence a low startup supply rail voltage. I would be looking in this area. Tell tail signs of faulty capacitors are from their tops bulging up with possible brown liquid discharge, or if their plastic base inserts give first with the pressure, these pop out from the can.

I put heat-sinks on U14 and the regulator above it and the TV has been running fine all day. Always shut off after 14-30 minutes before. Heatsinks were just 1/2" x 1" metal strips with silicon thermal compound that I taped up to hold in place to temporarily test, as it is obviously a heat related problem.

If you try it and it works for you, post it here.

I have exactly the same problem, my unit has been sent to the service centre 3 times already and they still haven't fixed it. It appears to be a main board issue. I will send it back again for servicing and will NOT take it back unless the main board is replaced.
