Multi-function camping set

Tour of the property

I bought this unit for 6€ as the store was emptying its stock before the impending shutdown of the analog TV transmitters. It was marketed as a multi-function set for camping. It really has it all :


Checking out the features. I think you'll enjoy the part where I test the radio without recording any sound.

Pointless video of me fruitlessly trying to find an active channel one year after the transmitters have been officially shut down.

I didn't particularly care for any function besides the TV to I didn't check them in detail but the TV and radio seemed to work fine. I probably wouldn't have trusted my life in the compass and thermometer which both seem to be around 10 degrees off. I doubt anyone in their right mind would be interested, but I still scanned the manual (in French) for posterity.

The insides

Naturally next step was to take it apart and see how the TV portion could be separated from the rest. Here it lies eviscerated :

Radio & lamp board


Board top

Board bottom

Lamp

The left side of this board handles the radio function. From the top is the AM antenna, next the tuning capacitor, and then the CD2003GP integrated radio chip. On the right side are some switches and the inverters to generate the high voltage needed by the fluorescent lamp.

Audio board


Board top

Board bottom

The black DIL package IC at the bottom is a CD7313GS audio power amplifier. Both the audio from the radio and TV are routed through this board.

TV board


Board top

Board bottom

CRT

Close-up of the TV decoder chip

The whole board is built around the CD5151CP. Excluding passives this chip seems to have everything needed to build a TV receiver : video and audio intermediary frequency, tuner frequency control, automatic gain control, FM detector for audio, detection of synchronization pulses and horizontal and vertical deflection oscillators and drivers. There is also a TA8164P, which is a radio tuner IC. I'm not sure what its purpose is, since the CD5151CP already has integrated FM decoding circuitry. It may have something to do with the SECAM-L standard. In any case the CD5151GP is where I'll be looking to try to access the video signal.

Looking around

The datasheet of the CD5151GP is only available in Chinese, which I unfortunately cannot read, so I tried poking around a bit on the PCB and pins of the CD5151GP. I didn't learn much from this, only that the image seemed to stabilize when I applied a composite signal from a game console on pin 6 of the IC, so I figured there must be some synchronization circuitry here. However that was not enough, and since there are no more TV transmitters operating in my area, if not the whole country, I couldn't tune the receiver and find the familiar composite signal anywhere. Fortunately I found out that the CD5151GP is equivalent to the AN5151N (datasheet still partly in Chinese), which is itself equivalent to several ICs including the KA2915 for which I could find a datasheet in English.

Let's have a look at the block diagram :

Pin 6 is synchronize input, but more importantly pin 5 is video output. So if I cut off this pin and replace it by my composite signal, I should see something.


Nice start!

I'm clearly on the right path and there are some bits of the image I'm expecting appearing on screen. However the text is in black and there is a bright stripe going down across the screen and some horizontal lines that are not part of the image. Looking at the standard composite signal timings, the issue is clear : the signal is simply inverted, white text appears black and the synchrnoization pulses appear as bright stripes. Let's invert the signal using a BC337 transistor and see what goes :


Behold!

I'm quite happy to see this :-) Almost there. The image is still wobbly and not as crisp as it should be though. I'm thinking the wobbly edges may be due to some 50Hz superimposing on the signal or the beat frequency of the oscillators in my game console and the TV chip. In any case the oscillogram below shows that the inverter I built has a way too low bandwidth, all the high frequency components disappear and this is what causes the washed out picture. There is also a large DC component to the signal, but I'm not sure it matters since it still synchronizes well.

Oscillogram
Top is signal from the game console, bottom is crudely inverted signal. Amazing that it still shows something, actually :-)

Well that's where I'm at now, I'll post more when I figure out how to improve the inverter.

Sometimes there might be an issue with the interface of the app and due to that glitch you may not be able to perform an operation. To address this issue, you can use the help of the tech consultancies or you can connect with Cash App customer service for further help.

The send button is one of the most important buttons of the app as it’s responsible for the transactions. But if there’s a glitch, then you can get the issue resolved using the help of the tech consultancies or you can also get in contact with the Cash App customer service and speak to the rep.

If your HP printer is offline then it is quite obvious that it won’t be able to communicate with the laptop/desktop and your printing task won’t get done. To get it back online, make sure that your printer is connected to a power source and is turned on. If the LCD is blank then it is off. Verify whether your printer is in sleep mode and if it is then turn it online.

Edit...

step number 1 -> remove saw filter between pin 28 and pin 1 (not pin 2 as in original post) . then moving on to number 5,

6/. solder a 470mf / 16 v or more from pin 1 to nearest GND.

It should work. and fixing vertical rolling problem too. I would use a 2Kohm VR , instead of a 220ohm between pin 5 - 1. This is to supply a DC bias to the internal IFamp circuit of the IC.

. you got it all around. Put everything back on as they were, and try this, I use to do TV repairs for a living back on 1987....
1/. Removed the saw filter between pins 28 and 2
2/. Solder a 220ohm / 1/4 w resistor between pin 5 and 1.
3/. Solder a 1mf / 50 v capacitor with positive pin solder to pin 28,

4/. Solder a 1mf / 50 v capacitor with positive pin solder to pin 5,
5/. the negative pins of the above 1mf/50v capacitors connected to your composite video signal (1Vpp).

My image isn't usable at all. You can see the picture change when it's supposed to change but you can't make out at all what it's displaying. I think the horizontal sync is wrong because every column looks the same. I hooked it up to a raspberry Pi and opened a terminal window and it was possible to see a white bar at the top and bottom (task bar and window border), the rest was black and by pressing enter I did see new grey lines appearing. but for example it was impossible to see the desktop cause i flickered like crazy. Something isn't right there. I tried both PAL and NTSC (I live in a PAL region) and the TV in question is a little elta Germany 2209TB.

This was very helpful. However, I didn't need to invert or sync the signal. I just made sure the ground was connected on the composite cable.

Awesome write-up. You're attempt helped me complete my project!

I've just hooked up composite input to a Trakton TR-735 portable BW TV.
Note that I also had a dodgy picture. It wasn't until I also passed in the audio channel that the picture cleaned itself up!

Nice writeup, I plan to do the same thing with a 5" NTSC set. It would be nice if you had a picture of the screen with its stable picture.

I tried transistor BF 194 but it didn´t work. Then i find easy way: Simply 100 nF capacitor between composite video and cutted folio from pin 5. Then i added 10 K resistor from composite video in to ground that prevent the DC-current going to camera. B / W TV working great and picture is sharp!

Thanks, great info, saved me a lot of time! I had similar problems but didn't have to invert the signal, my problem was down to picking a bad ground point on my source, you may want to check yours?
