Check the horizontal o/p transistor I suspect it's shorted, find location Q14401, on the board it's marked as q401. it's located near the flyback on a heatsink. if it's bad the rca part number is 242224. good luck

TV wants to turn on but can't. Green on-light goes on, then sounds like a relay clicks off and it tries a couple times, but nothing happens.

Check and replace the shorted component/s in its horizontal output section circuit. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact the nearest service center.

10-year-old 32" RCA PIP TV just blinked off one morning after about 30 minutes. It makes a continuous high pitch sound, and the on/off switch is completely unresponsive. I assume this is a picture tube and...

It's not the picture tube(especially if image was good b4 it went dead). The high pitch noise is the power supply whinning because it's shorted or overloaded. I just fixed one of these sets - replaced the horiz. o/p transistor and flyback estimate around $120.00-$160.00

Hello cadillaczacc,

This could be you audio out put stage malfunctioning. As a test connect a head set to you RCA connectors for audio (Red and White RCA Audio out jacks) and see if there is sound (there should not be if the audio amp has malfunctioned). In addition check your setup menu to make sure the TV is not on mute mode. If the TV is not on mute and you do not hear sound from the headset connected to the audio out RCA jacks, then we can start looking at the possibility of an internal circuit problem.

I have the schematic so if you need help, and have a background in electronics, we can get this fixed. If you do not have a background in electronics I would suggest getting a qualified TV technician to fix this TV for you.

I hope this helps,

Thank you,

All the reports are showing the same problem the TV is in shutdown mode.

Something is wrong and it is refusing to start it makes a chirping or clicking sound. Solution is that it needs to be repaired nothing you can do unless you want to try replacing the motherboard yourself.

Rca tv mm36100

There is a common problem in this unit with R14103 (33k 2watt ) resistor that opens. When open SMPS will not load so no other voltages beyond the 5v source to click the relay.
Another possibility is the Horz. drive transformer, RCA p/n# 243859 board location T14451.
Either of these possibilities are inexpensive fixes reletively speaking, so I would advise having it estimated by a qualified shop for repair..

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.
