Direct answer to the question

I could not verify an exact schematic indexed under the PCB code 5800-A3T300-00. The closest confirmed resources I found are for Roadstar RS-5800, but those point to an audio product, not clearly to the board code you wrote:

• Elektrotanya lists a “ROADSTAR RS 5800” service manual, PDF, 6 pages, categorized as AUDIO. (elektrotanya.com)
• HiFi Engine identifies Roadstar RS-5800 as a stereo cassette deck. (hifiengine.com)
• Scribd also mirrors a Roadstar RS 5800 6-page document. (scribd.com)

So, if you need the electrical schematic for the exact board 5800-A3T300-00, the safest conclusion is:

1. 5800-A3T300-00 is probably a PCB/chassis number, not the commercial model.
2. The available RS-5800 manual may or may not match your board.
3. To identify the correct schematic, I need the brand + full device model, or photos of the PCB.

Detailed problem analysis

In service work, there are usually three different identifiers:

• Commercial model: what is printed on the front/rear label, for example RS-5800
• Chassis number: internal platform used across several models
• PCB number: silk-screen code printed on the board, such as 5800-A3T300-00

The problem is that schematic archives are usually indexed by commercial model or chassis, not by raw board code. That is why a search for the board string often fails even when the real service manual exists under another name.

From the indexed sources I could confirm:

Item found	What it suggests	Confidence
Roadstar RS 5800 service manual on Elektrotanya	There is a service document for a product called RS-5800	High (elektrotanya.com)
HiFi Engine listing for RS-5800	RS-5800 is a stereo cassette deck, not obviously a TV mainboard	High (hifiengine.com)
Scribd mirror of Roadstar RS 5800	Same 6-page document likely circulates elsewhere	Medium (scribd.com)

This means the earlier hypothesis that 5800-A3T300-00 is definitely a CRT TV chassis is not verified by the current indexed evidence. The stronger currently verified match is Roadstar RS-5800 audio equipment, but I cannot guarantee that this is the same hardware as your board.

Current information and trends

For older equipment, the practical trend is:

• documentation is often preserved on repair archives rather than manufacturer sites;
• legacy manuals are frequently mirrored on communities such as Elektrotanya and catalog sites such as HiFi Engine; and
• indexing is usually by model name, not by board silk-screen code. (hifiengine.com)

Supporting explanations and details

To get the correct schematic, please send one of the following:

• exact brand and full model from the label;
• a photo of the whole board;
• a photo of the sticker/barcode on the board;
• the names of the main ICs on the PCB;
• a photo of the rear label of the device.

With that, I can usually determine whether 5800-A3T300-00 belongs to:

• a cassette deck / audio unit,
• a CRT/LCD television chassis,
• or a reused OEM mainboard.

If you already have the board in hand, check for these clues:

• Audio deck indicators:

  • motor connector
  • cassette mechanism
  • Dolby / audio preamp ICs
  • line-out / REC/PLAY connectors

• TV board indicators:

  • flyback transformer or CRT neck connector
  • tuner can
  • LVDS connector
  • backlight inverter / power section
  • large heatsinks near video or power ICs

Ethical and legal aspects

• Service manuals may still be subject to copyright; use archival copies only for repair and personal technical reference.
• If the equipment is mains-powered, use proper isolation and discharge procedures.
• If it is a CRT device, there are serious high-voltage hazards.

Practical guidelines

Recommended next steps:

1. Do not search only by 5800-A3T300-00.
2. Search or identify:
   • brand
   • full model
   • chassis
3. Compare the board physically with the Roadstar RS-5800 documentation only if your device is clearly an audio cassette deck. (hifiengine.com)
4. If you send photos, I can help map:
   • power supply section,
   • audio path,
   • motor control,
   • regulator rails,
   • test points.

Possible disclaimers or additional notes

• The exact board-code-only match was not verifiable from indexed sources I found.
• The RS-5800 manual is only a probable lead, not a confirmed match to 5800-A3T300-00. (hifiengine.com)
• The earlier claim that this is certainly a Skyworth 3T30 CRT chassis should be treated cautiously unless you can show the actual board layout or main IC set.

Suggestions for further research

If you want, send me:

• front and back photos of the PCB,
• the device brand/model label,
• or the symptom of the fault.

Then I can do one of these for you:

• identify the correct chassis,
• reconstruct the probable power rails,
• mark test points,
• or help you find an equivalent service manual.

Brief summary

At the moment, the only verified near-match is the Roadstar RS-5800 service documentation, which appears to be for an audio cassette deck rather than a clearly identified board 5800-A3T300-00. (hifiengine.com)

If you send the exact device model or a PCB photo, I can narrow this down and help you find the correct electrical schematic rather than a possibly unrelated manual.
