Question about RCA F32450 32" TV

1 Answer

Will not turn on.

I checked power supply and found voltages to low, caused by shorted horz.

output transistor (TL02).

Replaced TL02 transistor and power supply standby voltages returned to normal. But can not get set to turn on. I can see the green lamp at the on/off button cycle on and off and the horz. circuit follow suit, but will not

maintain on condition

Re: will not turn on.

  • proceed as given after your power supply is ok (your statement)
  • isolate power supply from h/output stage.
  • check diodes & capacitors connected with flyback transformer.
  • check for print short.
  • ckeck h/output transistor.
  • connect supply to h/output stage.
  • put on the set.
  • hope this will help.
  • good luck

still there is a drop in voltage then your fly back transformer faulty.

UndefinedI've checked a Panasonic crt color tv model TC-21fj20p, and I find a hard way to discover the cause of the problem until now.. The set has a good primary voltage supply. No problem with the IC...

Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
Any short circuit at the horizontal output section circuit will shut down all the secondary SMPS voltages, as there is short circuit protection circuit to all Sony TVs.

Jvc av 29x56sat no power at secondary

There should be a short circuit at its +B side. Just disconnect all the load from the +B, connect a 100W 220V filament type bulb [Not CFL or other type], as load, and switch the set ON. If power supply is OK, the bulb should glow with half its intensity.
If it does so, check the horizontal scan output transistor, which drive the LOT (Will be screwed to a metal heat sink), for any short. De-solder it out from the circuit, and switch ON the set, after connecting the +B voltage; and now measure the +B voltage. If it is found OK now, be sure that the horizontal output drive transistor is leaky, should be replaced. To get more details, If you wish to get further assistance from me, come over by Fixya comment. OK. Good Luck.

Tv is not working when it is switch on tv become standby

This is a common fault. Check power supply output of SMPS. if its low/drop, then disconnect supply to horz.o/p., and check supply again. If supply is normal when open load this means there is a defected components in horizontal output section. If the supply is normal before open load, check horz. osc and H.driver. Also check reset voltage at microprocessor and standby circuit.

our tv set need to be serviced. Here are some tips:
1. Open main fuse. The fuse is clean but interrupted. You can try replacing it with one o the same value.
2. Fuse Blown or blackened. Short in the rectifier bridge or in the switching transistor. Out of the power supply: supply line rectifier (100/150V) shorted.

When we try to turn on the tv (toshiba model 32A43) it makes the sound of turning on then off and the screen stays black and a red light by the power button keeps binking

You're either losing high voltage or power supply is not producing the horizontal drive signal, Check for 130v on the collector of the horizontal output transistor, if you're missing your voltage, you have a power supply problem. If voltage is too high you have something open in the power supply such as a low value resistor. If its low, something is shorted in power supply, possibly voltage regulator ic.

Sharp tv primo 21`inch turn on red light only

check your horizontal transistor maybe it's shorted replace horizontal transistor or maybe the fusible fuses are open check for open resistors at the horizontal section of the circuit.

Will not come on only the red light blinks and then stays on but no picture or sound and can not turn off have to unplug

Check the horziontal out put TL02 ( 2SC5148) transistor. Its possibly shorted. Pull the transistor out, ohm it out to see if it is shorted. Replace the TL02 if its shorted. Before powering the set up. Pull out the glass fuse in the power supply. Take a 100w light bulb and wire it a cross the terminals where the fuse was. Turn the set on, if the bulb lights up than goes dim, there is probably no other shorts. If if stays bright then there is some else in the circuit that is shorted. If there is anything else shorted its more than likely the flyback transformer. If the bulb is dim, go a head and put the fuse back in and see if the set comes up. Hope this is helpful

Sony trinitron won't power up.

usually the horizontal output is shorted due to loose connections on the transistor, driver transformer, or driver transistor. this will cause failure of 2 power transistors in the low voltage supply and open up a low ohm circuit protector. any reputable shop can repair this for a fraction of the replacement of the set. and the repair lasts.

Blawn AC fuse

Almost every modern set will just go into power supply shutdown if the horizontal output transistor is bad or other problems place a heavy load on the secondary side of the supply. Usually that results in a ticking or whistling from the set, but it won't blow the main fuse. A blown fuse typically means shorted parts in the primary side of the power supply.

The switching supplies used in today's sets can be a real pain. Check for a shorted input bridge rectifier or shorted switching transistors. There are also optical isolators used to provide control feedback and they can go bad, causing the supply to run away and blow up parts. A service manual or at least schematic diagram is very helpful. You might be able to find one online. I've checked my files and I don't have anything for the chassis used in this set.

No power.

Usually, in those Sony sets, a crack developes on a small transformer in the horizontal drive circuit, which causes the horizontal output transistor to short. This immediately shorts out the switching transistors in the power supply and blows the Sony 0.1 ohm resistor fuse. A shorted flyback (high voltage) transformer will also have the same result. The power supply does NOT need to be replaced. The parts should be replaced, the flyback checked and the board resoldered by a qualified tech familiar with Sony sets.
