Can you read the letters and numbers on the transistor your needing to replace? If so post the numbers and I will post a link where you can order them or their substitue.

Horiz deflectiion bad


if the transistor gets very hot in under 30 seconds the problem is in the driver circuit in front of it--open or off value cap is most common. 5 minutes is waiting too long---touch the face of transistor--can be mildly warm but not HOT.

Hello,
The Horizontal Output transistor needs to be changed as it is most likely shorted. The current transistor on this set is a 2SD3402 (no longer available) it's new replacement part number is the 2SC5902.
Order 2 2SC5902 Horiz Output transistors.Replace the transistor by it self once and if all is ok then fine.
If not replace it again and also the the Flyback HV transformer. The HOT transistor is probably shorted again and the transformer is causing it.

The set tries 3 times to come on (3 blinks) if there a problem such as a short, it will cycle without turning on. Unfortunately your set is notorious for having bad flyback transformers. Most likely the horizontal output transistor is shorted as well. Common causes for your symptom are: LL05 (horiz out transformer) RCA part# 257805; TL 02 ( horiz output transistor) 2SC5148; and open connections on the printed circuit board at LL 04 and L14401 (coils) all of which can cause the horizontal output transistor to be shorted.

No picture High pitch squeal RCA F36650


Confirm service # from back of set = F36650 YX01..........
Transformer red HV lead attaches to CRT & Horiz output
xistor is on heatsink next to transformer = 2SC5148 .........
Rca part # 257805 or ASTI 2078 and 237470 xistor............
Do not use a generic transistor = name brand only............T.

Check Horiz. output transistor = shorted?
1)replace with first quality transistor
2)solder horiz driver circuitry
3)replace shorted converter transistors (2SC4834)
4)Replace open R607 .1 ohm 1/2 w.fusible (resistor ok)
   test.......T.

JVC AV-36260 Is there a fuse in this TV or is it a circuit breaker, if it is where is the fuse / circuit breaker located. I am am electrical engineer, but can not find any specs on the inside of the unit


All modern TV's have fuse devices,some glass,some chemical.

However,a blown fuse comes from a short circuit,which I'm sure

you are well aware.Let's talk diagnosis--What is your set doing

or not doing?? Is it dead?==No "on"?? If there is no bad fuse,the

most common solution is a bad capacitor in the power circuitry

number sequence==900's. Ex..C953    value== 1000mf/35v.

Other caps in power supply may be weak.

2) Check Horiz output transistor---shorted? Look for blown B+

fuse + weak or open C523 1mf/160v in horiz drive circuit.Replace

horiz out with high-quality OEM transistor only.I use JVC only

on 32" size & bigger ( you have 36" ).

  Let me know by rating this solution...thanks...T.

Power not turning on


Power supply failure! Requires several steps==
1)Pull main board & power supply board
2)Check horiz output xistor = shorted? Replace w/ first quality
3)Carefully solder horiz drive circuitry from HDT to base of o/p
4)On power board--replace shorted converter transistors 2SC4834 and R607 .1 ohm 1/2 watt fusible
5)reassemble.     Let me know how it goes.....T.

Tv problem


The F27442 uses the CTC203 series chassis and that symptom is very common. If the horizontal output is shorted you MUST resolder the coil in series with the base of that transistor and the pins of the small horizontal drive transformer. When they have been properly resoldered you can put in a new original horizontal output transistor. If the output transistor shorts out again then your flyback (high voltage) transformer is shorted and needs to be replaced.
