| Model | Display | Faults and test points | Other details |
|---|---|---|---|
| This demonstrator (EL-DSO-10336) | Colour CRT, CCIR-B PAL-G | 48 fault switches; 55 test points | Sliding PCB with lock and key; remote control |
| LED TV Trainer | HD LED | 6 switched faults; 5 test points | HDMI and USB inputs; remote control |
| LED/LCD TV Trainer | 32-inch flat panel LED/LCD | 40 fault switches; 40 test points | Antenna, composite, analogue video, VGA and audio inputs |
Choose this demonstrator when the course covers the CRT colour receiver stage by stage and you want a large fault set on one panel; the flat-panel trainers suit courses built around LED or LCD sets.
What Is the Color TV Demonstrator Used For?
It teaches how a PAL colour receiver works and how to service it. The tuner selects the channel, the video IF stage at 38.9 MHz amplifies the picture signal, the sound section takes the audio carrier, and the video and chroma section recovers the brightness and colour information that drives the CRT. The vertical and horizontal oscillators and output stages scan the beam across the screen, while the power supply and system control circuit run the set. Students follow the practical and theoretical side of each block, observe signals and measure voltages at the test points, and use the fault switches to see how a fault in one section shows up on the picture or sound — a core exercise in TV and consumer-electronics servicing at ITI and polytechnic level.
What to Specify When Ordering
- Quantity — the number of demonstrators for your workshop.
- CRT or flat panel — this CRT set, or one of the LED and LCD TV trainers compared above.
- Bench instruments — multimeters and oscilloscopes are separate catalogue items and can be quoted on the same enquiry.
Frequently Asked Questions
Which TV standard and IF does it use?
It follows CCIR-B PAL-G with 625 lines, covers 230 channels through a 75 Ω RF input, and uses a video IF of 38.9 MHz and an audio IF of 33.4 MHz.
How is the circuit board mounted?
On a 19 x 15 inch sliding horizontal PCB with lock and key, and the component-mounted PCB and CRT section are in full view.
What can be controlled from the remote?
Volume, brightness, standby, colour, contrast, channel selection, audio mute, AV mode, zoom, swap, scan and child lock.
What mains supply does it need, and how heavy is it?
It runs on 220 V AC +10% at 50 Hz and weighs about 25.0 kg.
How does it differ from the LED TV Trainer?
This demonstrator is a CRT colour set with a larger fault set on its front panel. The LED TV Trainer is built on an HD LED set with HDMI and USB inputs.
What should an export enquiry include?
Give the quantity, destination country and port or city, delivery terms (for example FOB or CIF), any packing or labelling needs, and the tender reference if there is one.
Who manufactures the Color TV Demonstrator?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, and supplies it direct as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a training equipment and lab instrument manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The demonstrator is made in JLab’s own works, not sourced from a trading house, so ITIs, polytechnics, dealers and importers order directly from the maker. The company holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise and Importer-Exporter Code 3317504552. JLab exports worldwide and ships to buyers in every region — for example Ivory Coast in West Africa, Brunei in Southeast Asia, Italy in Southern Europe, the USA in North America and Kazakhstan in Central Asia. Tender buyers can refer to the JLab lab tenders page.
