Akinek van ilyen tévéje nem tudna készíteni néhány képet a panel fóliás oldaláról, hogy a TDA2579A lábai forrasztásnál hogy vannak helyesen?
SM-ből nem kivehető

Mester urak!
A fenti tv-hez szeretnék segítséget kérni. A kép nagyon sok idő mulva jön be.10-15 perc is lehet. Amíg nincs kép a TDA 6101Q nem ad vissza jelet a TDA 4780-nak. A 6101-eken a 12 és 200 V megvan, a többi akkor áll be rendes értékekre amikor elkezd működni. Ha egy pillanatra kikapcsolom akkor is sokára jön be a kép, de kikapcsolásig megmarad. Ha bejön a kép a fehér egyensúly se teljesen ok. A kék egy kicsit gyenge. A képcső elfáradása az oka a késői felállásnak? Ha igen akkor nem lehet valamivel elősegíteni a beindulást? Már ugye képcsőcsere nélkül. A képcső típusa W66ESF 002x44.Azt hallottam, hogy ezeket a Philips csöveket nem sok sikerrel lehet regenerálni.
Előre is kösz.: kollerp
Dear Expert
The details of my TV is as follows
1. Philips 40PFL4707/F7 Manufactured March 2012
2. SMPS Board BA21P6F01 01 1
3. SMPS board has a sticker that says A21P6MPW C 7219720
4. This is a 110v Mains Supply TV sold in USA
5. I imported this from USA into my country where we have 230V.
6. I have a simple winding transformer that converts 230v to 110v
The TV has been having this problem. Here are the steps
1. Mains power on
2. Front panel white led blinks 6 times
3. Philips logo display
4. TV shuts down immediately
5. Nothing happens. If i press power button on TV or remote nothing happens
6. Have to power off and then wait for few minutes to experience same repetition.
Last two days, tried several times, only once the TV started and after 10 minutes it did auto shutdown as there was no input signal connected.
Does this indicate issues with SMPS or main cpu board ? Even if its faulty, how did it start once ?
More testing done as follows
1. Removed all connectors. Cleaned all three pcb with liquid cleaner. Cleaned all connectors externally and internally ( holes) using painting brush. Allowed everything to dry.
2. Reconnected
3. Started. This time, went past the Philips logo. I could connect a macbook via HDMI and play youtube videos on the TV for ~1 hours.
4. Using remote, entered service mode and initialized ( factory reset) the TV
5. For 1 hours of proper run, measured voltages. LED+24v was showing properly at 24v, AL+3.3v was at proper 3.3v and the P-ON-H1 was properly at 3.3v
6. After about 1 hrs, the screen shut down. The LED+24v is showing at 6v, AL+3.3v at 3.3v and P-ON-H1 is a 0v. This indicates the main cpu board has turned off the P-ON-H1 signal.
7. Power off, wait for 2 min. Power on... same philips logo and TV shuts down. Problem repeats.
8. Firmware is Code TVNB010_00_PF_XX91_BA PIC code U10_CM08:_40A_C7W_R_02. Did a google search and found no references if this firmware needs any upgrade.
requesting experts next steps to root cause the issue. I suspect the main board is bad and the SMPS is good. What if I manually put a wire from AL+3.3v to P-ON-H1 ? will the TV be on or is it risky for the main cpu board ?
I am attaching the service manual for this TV
