4 year old TV keeps going OFF. Sometimes will

This is probably due to failing PSU capacitors. It is fixable.

serial number on 6.17.8.1

Good day!!!!


You have a better chances if you have failing bad capacitors on the power supply board...


bad capacitors sometimes bulged on top,sometimes not...if the caps is bulged you can easily identify it..







Thanks for using fixya..

It can Have one of 2 Troubles, The Inverter Board is Defective or the Power Supply has bad Capacitors. I found 3 Capacitors known to go bad in that set. Replace the 10 Volt Capacitors with 16 Volt Caps and they will last forever.

red light flashes 4 times then stays on for about 5 seconds then flashes 4 times again any idea what this means and how i can fix it tv is about 4 years old and only just started doing this

if the sound goes out its not a tube problem . a bad tube would have no effect on the sound .you problem (my guess) is in the power supply . a modern tv power supply has parts of it that stay on all the time unpluging it is not the problem its when you plug it in ! the power supply gets a JOLT . you might get away with it ,you might not . thats why we install surge arrestors on power plugs and with expensive tvs i recomend a UPS a power unit that keeps the tv powered even wnen the line power is out . thats keeps everthing in the sets nice and even ,so the tv lasts longer ... a modern tv turned off uses about 1.40 in electric a YEAR in standby mode , so what are you saveing if you send you set to the landfill early and have to buy a new one ? over 1.40 in electric ? . turn down you water heater or something else simple dont be blowing out you electronics for the sake of a few cents ..... good luck .... if this answer helped please rate a 3 or 4 , this high rateing will hepl keep me in the paid answer department . thank you

I still have that problem. I calle Mfr and also spoke to repair shops recommended by them and they said they estimate a cost of 300-400$ or so approx. I am waiting to buy a new LCD which could be few 100 more but at least dont have to live with the old one and keep spending money...

The bad news,your set needs a new inverter board installed.With persistence to sharp,you might be able to get them to pay for the parts.

same problem... tv turns on and off repeadly while the green light flashes. seems as if the tv keeps restarting. please help.

If it's staying on for just a short period of time it sounds like there is a sensor that is giving the unit a faulty condition (Perhaps for reason or due to a fault in the sensor). There are normally a few temp sensors in the TV around the Lamp and Ballast. They may be bad, or the lamp or ballast is just generating too much heat.
