Philips 23PFL5522D/05, black screen red power flashes

[quartz]

Hello, have already had a suggestion of the control circuit board, after reading about the power problems on a monitor, like to check in case anyone has different know-how pls

The picture went slightly garbled and flakey, sound was fine, displayed this "stable" for 5 minutes. the next day, was good again The day after, went black

connecting to power after 10 mins disconnection, the red power flashes about 6 times, then does about 4 flash-flashes, then the speaker starts blipping, and the red flashes fast constantly, with the speaker blipping every few seconds

ther's no obvious component failures or burn out, altho a couple of the caps on the power have very slight bloating

there is a fizz/quiet/fizz/quiet

many thx

Photos of both boards and swollen caps please.

Part number of power board? Do not keep the unit plugged in. The fizz-quiet routine can be a mains cap gone bad. If it fails -badly- while plugged in or trying to turn on, a $10 repair could be $100.

I can't locate a service manual, but PlainBill may have a source once he wanders through here.

stock photos attached, but circled the caps which have slight bloat (very, very slight, just to the touch)

but have no other visible faults on either of them, or signs of burnout, or any smells

power: DAC-12M058
ctrl board: 3139 123 62613 WK713.5 (this replacement is what ive been advised, at about £40)

i believe there is another board hidden under some metalwork on the left.

i think i attached inline wrongly

If your caps are the same as the -bloated- ones in the pic , then a complete recap is called for of the power board -first-. If your mains cap is also Rubycon, then that can be left alone.

The fizzing is the power supply trying to start and failing because of the bad caps.

Again, picture attachment is good!

By the pic, it seems you have 13-15 caps to replace.

Google cache shows something from ebay.co.uk for the power board ~£50 incl. shipping. Nothing presently though. If you were to buy the board, you'd most likely be back in the same boat in a short while.

If the Power board is bad, there is no way to conclude the Logic board is a problem, unless you can swap it to another set.

thanks when you say bloated, there's the 3 caps which have a slight bulge to them, does even the slight bulge indicate the insides are bad, do 3 caps like that recommend replacing the whole set (all the rest are flat - not a problem if it is, just to check)

A slight bulge is like being a little pregnant.

The rest need replacement or you'll be chasing problems for a long time.
