🖥️ Sony Bravia TV Not Turning On or Showing Errors? It Might Be Time to Replace the Main Board
Is your Sony Bravia (often mistaken as "Bravo") TV showing a black screen, blinking red light, or stuck in a boot loop? These are common symptoms of a faulty main board or power board — and the good news is, it can be fixed without replacing the whole TV.
At Gary’s Computer Repair Service, we specialize in Sony Bravia main board replacements — bringing your high-quality smart TV back to life quickly and affordably.
🔍 Common Sony Bravia Board Issues
1️⃣ TV Won’t Turn On
The LED blinks, but nothing shows on screen? This often points to a main board or power board failure.
2️⃣ Red Light Blinking Codes
Sony TVs use blinking lights to indicate errors — 5, 6, or 7 blinks commonly relate to T-CON, main, or backlight board issues.
3️⃣ HDMI Ports Not Working
If your PlayStation, Blu-ray, or cable box isn’t detected, your input/output board could be faulty.
4️⃣ No Sound or No Picture
A damaged main board or signal board can stop your TV from displaying picture or audio even if the screen is lit.
5️⃣ Stuck in Boot Loop or Logo Freeze
If your Sony Bravia TV gets stuck on the logo or continuously restarts, firmware or board-level failure may be the cause.
