Thomson TV Standby Light Flashing Can't Post

G'day,

What does it mean when my CRT Thomson 66cm Widescreen TV wont turn on, and the standby light flashes

{pause}

Yes, it must be pushing 5 years old, which is supposedly old age in modern electrical equipment, but I'm really hoping to get at least another 6 months out of this set so I'm out of uni and earning again.

First sign of trouble actually started about 3 months ago. It would no longer turn on from standby mode. Had to physically turn the power button off, wait 5-10 seconds, then turn it on.

Today, my fiancée turned the tv on, and within a few minutes it turned itself off, and then the Standby Light did the abovementioned flashes. Repeated attempts to turn it on result in the same flashing.

Any advice appreciated.


cheers

cosmic

Oh, ICC17 has found a lot more results that 28VK25EA...

With the 2-7 pulses...

"The Detection System has detected protection on more than three occasions"

&

"LOPTx - comes with mod kit 35175720. Also check FOP chip IF01 & cct prot ZL11 for damage by LOPTx"

Though neither of them mean anything to me... is that sounding like something worth repairing?

the flyback transformer goes on these and sometimes takes out the other parts mentioned.probably worth fixing unless its over 5 years old and you really really want a new LCD bigscreen!!

Try this. Remove DL75 (located J8) on the top side panel, this defeats the protection to show fault. Now found dark picture as RL03 or RL01 is open.
