RCA TV F31317 - can't turn power on - suddenly, it stopped workin

RCA F31317 User Manual

Most likely you have a bad highvoltage transformer and possibly a shorted horizontal output transistor. The transistor can be checked with a volt/ohm meter. Check collector to base. It should be over 1000 ohms. The transformer can be tested for inductance with an inductance meter or "ringer". One or both of these can cause the problem you described.

Hi
Please tell me if you can see any burned wires or components or can you smell something burning .

DUDEEE this exact same problem happened to me!!!! what happened was it was workin fine then it started turning on and off, then now it goes through these weird phases where i cant turn it off using remote or the power button. every button on the side of the tv and the remote doesnt work. so i have to unplug it to turn it off, what a messedup problem!!! im taking my LG 32LB9D to the tv shop tomorrow i hope to get it assest and possibly fix, ill tell u how to solve the problem if my tv is fixed. :)

the front panel assembly is rca part # 237420
I assume your chassis is a CTC203
Un plug the fpa and see if problem still acts up
you may not be able to find one
then try replacing the sticking buttons on it

R14109=750ohms 5% 1/4w (Resistor(750r5%.25W/R14109/179317) There is much more likely wrong with the TV. Resistor don't normally burn out with help, say, without a failing flyback transformer and possibly taking a transistor or two with it. If you need the manual, go to http://www.samswebsite.com/photofact/pf_search.asp and type in "F31317" into the search field, you will several listings. If you decide to replace it yourself, here's some more part numbers in case you need them.

in this tv proction is geting on offen

Sounds to me like there is an issue in the control circuit, and quite possibly the micro itself. If you have issue with both the remote and buttons I am thinking a microprocessor issue since they normally enter the micro at different locations and therefore would not have a single component cause a failure across both of them (Except the micro of course) Best option may be a service center.

There is going to be a wire that is connected to the back of the tube. The item that wire comes from (Flyback Transformer) needs to be replaced. Also, the HOT (Horizontal Output Transistor) is likely bad as well. It'll be a 3 pin unit connected to a heat sync around the Flyback.

The unit is in shutdown (There is a failure in the unit). Repair should be rather inexpensive if take to a repair facility (I'd guess about $80.00 depending on labor rates in your area). And most will give you an estimate for very little ($20-40)
