TV Stuck on Logo or Keeps Restarting? Expert Mainboard Repair Services in Riyadh
By Mr. Kawsar, Lead Technician at Saja Riyadh Foundation
A Smart TV is essentially a computer with a large screen. Just like a computer, the “brain” of the TV—the Mainboard (or Motherboard)—can fail. When this happens, your perfectly good screen becomes useless.
At Saja Riyadh Foundation (Al Tahliyah St, Al Aqiq), we specialize in complex chip-level repairs. While many shops will tell you “change the whole board” (which is expensive), Mr. Kawsar and our team have the expertise to repair the specific damaged components, saving you money.
We provide these specialized electronic repairs across Riyadh, from Al-Malqa in the North to Al-Shifa in the South, from Al-Yarmuk in the East to Diriyah in the West, and from Al-Qadisiyyah in the Northeast to Labn in the Southwest.
Top Signs Your TV Motherboard is Failing
How do I know if my TV mainboard is broken? Look for these signs: 1. The TV turns on but gets stuck on the brand logo (Boot Loop). 2. The HDMI ports stop working (No Signal). 3. The TV freezes or responds very slowly to the remote. 4. The LED indicator light blinks in a specific pattern.
1. The “Boot Loop” (Stuck on Logo)
This is very common in Android TVs and Smart TVs (Sony, TCL, Skyworth). You turn the TV on, see the “Sony” or “Samsung” logo, and then it freezes or restarts. This is usually a software corruption or a failing EEPROM chip.
2. Dead HDMI Ports
If you plug in your PlayStation or Receiver and get “No Signal” despite trying different cables, the HDMI controller chip on the motherboard may be burnt out. This often happens due to power surges through the HDMI cable.
3. Distorted Audio or No Sound
If the picture is perfect but there is no sound (and you’ve checked the mute button!), the audio amplifier IC on the mainboard might be damaged.
Repair vs. Replace: Sianna TV Riyadh Approach
Many repair centers in Riyadh are just “parts swappers.” If a board has a small fault, they make you buy a new board for 600-900 SAR.
We do it differently:
- Component Level Diagnosis: We use multimeters and oscilloscopes to find the exact failed capacitor, resistor, or IC.
- Micro-Soldering: Mr. Kawsar is skilled in micro-soldering, allowing us to replace a 50 SAR chip instead of a 900 SAR board.
- Firmware Flashing: Sometimes, the hardware is fine, but the software is corrupted. We have a library of original firmware for Samsung, LG, Sony, and Chinese brands to “re-flash” your TV back to life.
Why Do Mainboards Fail in Riyadh?
Living in Riyadh presents unique challenges for electronics:
- Heat: Electronics hate heat. If your TV is mounted in a cabinet without airflow, the processor overheats.
- Power Fluctuations: Voltage spikes are common. A sudden surge can fry the sensitive HDMI or Power ICs.
- Dust: Dust accumulation inside the chassis can cause short circuits on the fine pins of the processor.
Expert Advice: We highly recommend using a surge protector for your TV to prevent motherboard damage.
Brands We Specialize In
Sony Android TV Repair
Sony mainboards are complex. We specialize in fixing the “Blinking Red Light” errors (4 blinks, 6 blinks) which often indicate motherboard communication failures.
Samsung Smart TV Repair
Samsung Tizen OS boards are robust but prone to HDMI port failures. We can replace the HDMI ports directly.
Chinese Brands (TCL, Skyworth, Nikai)
These TVs offer great value but often suffer from software “bricks” (where the TV won’t boot). We have the specialized programmers to reset these boards.

Frequently Asked Questions (FAQ) – Motherboard Edition
Q1: My TV is stuck on the logo. Can you fix it without replacing the board?
Answer: In about 70% of cases, yes. We can often “re-flash” the software or replace the memory chip (eMMC/EEPROM), which is much cheaper than a new board.
Q2: My HDMI ports stopped working after a lightning storm. Is it fixable?
Answer: Yes. This is a classic surge issue. We can often replace the HDMI controller chip or repair the trace on the board.
Q3: How much does motherboard repair cost?
Answer: Chip-level repair usually ranges between 200 SAR to 500 SAR depending on the complexity, whereas a new board can cost double that. We always attempt repair first to save you money.
Q4: Do you service my area?
Answer: We cover the entire city. Our technicians travel from Al-Malqa in the North to Al-Shifa in the South, from Al-Yarmuk in the East to Diriyah in the West, and from Al-Qadisiyyah in the Northeast to Labn in the Southwest.
