Question about Philips Magnavox 20MT4405 20" TV

Open Question

Magnavox 19PRC1 My set has lost its horizontal controls. I get great sound but just lines most of the time. Sometimes, for a few seconds, I actually get a picture, but most of the time just scrolling lines. There's no controls on the back and no visible way to get into the Tv.

There aren't any adjustments anymore. This can happen as parts inside age and values change. Also solder connections can fail over time and cause problems. The problem you describe can be in any of several areas of the set. There really isn't anything you can do yourself to repair this. If you want to keep the TV you can get an estimate for repair, but this might be a good time to check out sale prices on new TV's and think about replacing it.

Most Probably the Vertical Output IC has failed. If it has, it also could cause resistors that supplt the +/- Voltages to the IC to fail as well.
Hope this helps,

My (2) Philips Magnavox 27TS54 C101 have lost the picture accept for one white horizontal line.


Hi Dean,

White horizontal line then the unit automatically shuts off with a led blinking on the front panel is an indication of faulty vertical deflection circuitry.
The most common faulty parts is the vertical deflection IC (TDA9302H) itself. This IC is mounted on the aluminum heat sink near the flyback transformer. You have to replaced it with new one to resolve the issue. Click HERE to have an idea how much it will cost for the parts.

Hope I helped you.
Good luck and take care!

My Magnavox plasma screen tv, model number: 42MF237S/37 makes a clicking sound when I try to turn it on. No sounds, no picture, just the clicking noise. Things I have tried so far: 1) Turning the TV off...


You either have a cold solder joint in your horizontal deflection circuits or your or in your horizontal output circuit. please be careful due to the fly-back transformer still holds power even unplugged until you discharge it.( ground it out). Hope this helps.

TV turns off by itself


Thus the line connected to a surge protector or some kind of line protector. This can be consider.

Or if this is a crt type tv. This could be a fault on high voltage section. Horizontal output transistor or flyback. But check also for loose connection/solder crack. That clicking sound may be the relay in action.

hope i give some correct input.

Toshiba TV CX2789K Horizontal Line


Failure in the vertical deflection amplifier section. This is usualy from failed components, and sometimes cold solder connections. Most of the time, I found bad capacitors, and sometimes the output IC or transistors (depending on the model type) that have failed.

Take the set to a service center for an estimate. You may find it more feasible to buy a new set depending on the parts that failed and the time involved to do the work.

RCA F36674ET - Only beeps when turned on


Clearly shows problem in deflection area both horizontal and vertical section. Horizontal lines is due to vertical section problem and making bbzzzz is due to horizontal output transistor short and sometimes LOT SHORT.

My TV keeps shutting off


Tvtek is on the right track. The remote will not solve the problem. Sounds like a voltage regulator in HV circuit if it only lasts a few seconds. If it stays on for a couple of minutes, beam limiter cicuit is pushing to overload and shutting unit down. Magnavox set not hard to repair, but a 27" set is not cost effective to repair either.
