Re: Philips 22HFL3232D/10 hotel unlock?
Do you mean to use one of this eg Superior to Copy RC2573 remote? So i need also RC2573 which i cant find?
This 'Superior' remote is what i can find in my country...Leave a comment:

Re: Philips 22HFL3232D/10 hotel unlock?
I got universal philips remote which have ~8 philips presets. "setup" key on remote is not working. There is some function like audio, display mode (cinema etc) that is not available on guest remote but no setup menu Why its so hard to reset it to default or to access setup? No way around?

Philips 22HFL3232D/10 hotel unlock?
Hello. Got this tv with limited functions and with guest remote. Security level is probably on most high, i tried all posible codes like 319753info etc, nothing work! I tried upgrade firmware via usb, nothing happens. I dont have master remote to turn this hotel mode off, cant find one anywhere.. Is there any way, lets say to use universal remote and will it be able to enter setup menu? Is there windows program which can emulate it true ir sensor? I'm even thinking of upgrading firmware on cmos chip (like on pc mbos) with CH341A programer but firmware is pkg file (PS_2K10_DL_BUH-EU_MT5363_panel_2.02_110704_upgrade.pkg)...Last edited by slayernn; 11-12-2023, 11:27 AM. -
Re: DHC-EX77MD problem with display
Thanx. Thats it, display is near end, probably fillament that was red glow caused by bad caps, burn phosphorus layer over time. But, md is alive and that is more of importance
thanx again. Hope that this tread will help someone in repairing own display. Cheers!...

Re: DHC-EX77MD problem with display
One more question and im finished. I tried trick with 9v battery over fillament. Did it for around ~10sec glowing red and results are ~10-15% improvement but still uneven. I check out again voltages on display board/ic to compare with datasheet. Some voltages is not like it should be. Can you look at image and tell me what is posible reason for that? Is X1,X2 (resonator 5mhz) normal? Best regards!...Leave a comment:

Re: DHC-EX77MD problem with display
Everything looks fine with display board, voltage on check points etc, its probably that display is worn out? If im correct i have two choice, one is to put higher voltage on VF1,VF2 so filaments glow light red and then display is more visible by its light (which was in original state, probably ex owner did that with purpose). Or second choice is to add much more voltage across filament so that it burn phosphorus layer, that trick seems to help many ppl. Btw i have removed display board and checked VF1 to ground and VF2 to ground...Last edited by slayernn; 05-11-2019, 04:52 AM.Leave a comment:

Re: DHC-EX77MD problem with display
I made huuuuuge mistake so far.......i used "LP301" lead with connector (which connect to chassis) as ground for measuring!... Now i have used chassis as ground and ...everything is good on board, ~-29V (pin 3) and +5 (pin29) of cn305. Everything is fine with main board apparently. Problem lies on display board.. im not sure what i did so that fillament is not glowing red like before, but voltage across filament is ~3.3v which is fine. Maybe some caps on display board is critical and is off? Probably anode voltage is very low or so....Leave a comment:

Re: DHC-EX77MD problem with display
Well i just changed all what i think off.. most caps that i mention. Ac voltage on CN402 across pin 2&4 is 20.5V. What i realised now is that B+ line that goes to pin29(cn305) +5v is 0V! So display IC gets 0v on VDD. IC301 also draw 0v. Maybe faillure in D301,D302,D315,D316? Best regard friend....Leave a comment:

Re: DHC-EX77MD problem with display
Added new:
C309
C310
C301
C307
D310 (1N5230 instead of rd4.7esb2)
D305,D306 (1N4004 instead of 11es2)
Nothing changed. Sorry for spam, cant edit single post so to update results. Cheers!Leave a comment:

Re: DHC-EX77MD problem with display
New readings:
Q301: ~20v on collector , ~21,3v base, ~16v emitter
Q305: collector ~18.7v.
When i measure Q301, Q305 voltage start at ~15 and slowly increase to max, eg ~20v for collector voltage.Last edited by slayernn; 05-09-2019, 03:32 PM.Leave a comment:

Re: DHC-EX77MD problem with display
D309 is fine and also D305 & D306 fine. I have no clue, i tried everything, changed all caps related to VF1,VF2,-28v(B-) cn305 pins. Is C324 critical? I'm not sure,have to check out, but maybe that's the only cap i forgot to change. Mistery to meLeave a comment:

Re: DHC-EX77MD problem with display
I have changed C304 yes. Q301 collector show 0v. Voltage across C302 is 13.5v. -28v yes pin 3 (cn305), it show 0v .I will check D309 and will let you know. Regards!...Last edited by slayernn; 05-09-2019, 11:11 AM.Leave a comment:

Re: DHC-EX77MD problem with display
Update, in short. I changed:
c320,c324,c322,c323,c306,c305,c303,c302,c316. 0 volts Q 301,305, checked d305,d306 with diode test, seems to be ok. Checked D309,D310 ok. Checked some resistors, its ok. Display still very dim. Ac 3.2v between vf1,vf2. -28v third pin = 0v. Strange, what could be problem here? Best regardsLeave a comment:

Re: DHC-EX77MD problem with display
I add new C315,C316,C322,C323 and also put back old 100uf 25v to position C303 (there was wrong mark C320 on copper side of pcb and i use C320 cap which is 100uf 50v). Everything is very dim, barely visible. I have check between VF1,VF2 ac mode and its 3.2v. Strange but -28v pin to ground shows 0v! So filament voltage is probably good but anode(-28?) is not and thats why it is so dim. Here i will add schematic of display pcb which i forgot to add in previous post. Thanx for all, cheers mate....Leave a comment:

Re: DHC-EX77MD problem with display
Here is cd player manual, i belive i need to change C320 (33uf 50v)? I inspected main board and find out that there was wrong capacitor C303, 100uf 25V so i changed it to 100uf 50V (like one in manual). Beside that i changed few other caps with new one (except that c320 which i dont have). Now filament is not glowing visibly red like before but brighness/latters are even less dimmer then before, its bareilly visible. Any tips what to try for cd display? Thanx!...Leave a comment:

Re: DHC-EX77MD problem with display
And........ it was C007! Everything work like a charm now! Man you rox !! Now im going to fix cd display dim with your tips and will update here. Do you accept donations or so? Cheers!...
