Kids. the red light keeps flashing,i have noticed a transistor thats been shorted with just number 1205 on it which is located on Q803,my two year old son inserted something to cuase this problem,can you please give me a replacement number for that transistor-

Hello
It may be due to some sort of short in the horizontal output stage inside your TV. You just check the horizontal output transistor, can be located near to the Line Output Transformer [LOT]. It is the transistor that drives the LOT. Check whether it heats up abnormally or not. Anyway keep it out desoldered and check it for any leak. Especially its collector to base leak. If it is found leaky, replace it with the same type and number. If the replaced transisor also overheats, LOT is short. Replace the LOT also with Same Type and Number. Insist on same type and number. Never use substitutions. It is the most critical component in your TVs circuit. Ok
Have any further clarification, report to Fixya. They will give me alert.
Take all precautions before opening your tv by yoursef. Keep chldren away from you. let an adult beside you while you are working as a precaution. Never use metal chair while in work. Wear rubber or plastic footwear while working.

5 blinks is error code for short on 140 volt line inside the set; it usually means the Horz output transistor is shorted. If you have a ohm meter (used for checking fuses etc) there is a simple test to see if this is the problem.

Also associated with this is a bad capacitor near it (Location for the Transistor is C509 and the transistor should be location Q551)

Location numbers are printed on top of board near part; both parts are on (as seen from back) far right board near the large black part with big red wire coming out of the top.

Transistor is just to the left of it and cap forward about 3 inches.

If this information told you something you did not know rate this solution as very helpful as I do this here for free.

Its 2 times blink error code that shows +B volt supply (+135 volts) is shorted, most probably horizontal output transistor is shorted, replace it.
If you are good in soldering parts in circuit board then take out horizontal transistor, check it, found shorted then replace it with same number.

Horizontal output Transistor Q502 number is 2SD2578 and available in Part Store for $10
Let me know for further query, if any.
Thanks.

The 2 blinks usually mea an over current problem. Perhaps the most common cause of this is a shortde Horizontal Output Transistor (HOT). If you can solder, you should be able to repair this yourself. Realize that there are potentially dangerous high voltages present inside the set even when unplugged. Look for a 3-legged ransistor attached to a heatsink close to the flyback (part with large red wire coming out the top). The part will be marked C5438 or something similar. Post that marking here nad I'll confirm the entire part number.

Keep us posted.

Same problem with mine. Relays click, sound, no picture and a flashing power LED. I finally found a schematic online. I went through the high voltage circuits and found the power transistor 2SC5570 was shorted out. There is also a pico fuse in that area but my was not open. I replaced the transistor and prayed the flyback transformer was not shorted. It wasn't, I'm watching my old 36" right now. Not a bad fix (17.00) bucks. Wonder what a service tech would have charged ;)

I fixed the problem with the "no power on, low clicking noise". The NPN transistor (2SC5931) was shorted. This transistor controls the horizontal hold. The shorting caused the power supply to overload and restart, then recycle. This was the cause of the clicking noise. Unfortunately this transistor was over $50, most likely due to the extinction of CRT's. I did find a replacement transistor 2SC5552, which only cost $2 (but I was able to get it in Mexico). The location of the transistor is located on the left side of the TV (looking from the back). Directly in front of it is the high voltage transformer which powers the CRT (should have a thick red wire). The transistor is attached to a large aluminum heatsink. To remove the transistor you will have to remove the entire electronics assembly to you can easily get to the underside. This was the solution for my TV, but there could be other components damaged.

Hi Kim,
Ok , just be patient , we will try to locate for you.

Thanks,

your set may have shorted hori output transistor NTE2324.or bad capacitor by hori.

i had same problem after house power switched off 3 times in same day disconnected power left overnight worked ok i will still take tv for a service .
red light was blinking 10 times

Your tv does not need a reset,what happened something went bad inside the set and it needs to be replaced,if you are familiar with tv service you can start by checking the horizontal output transistor for a short,if he went bad it likely made the fuse or safety resistor open.If you are not too familiar with tv service be safe and call for assistance froma servicer.If you decide to go in looking for problems make sure the set is not plug in.Let Us know how it goes or if you need more information.
