Check to standby voltages, the three of the five and a 7.5 voltage going to the SSB main PCB if these voltages are there most likely have no horizontal drive.  You'll need to replaced the SSB part # 264120. I recommend that you have an authorized RCA servicer replaced the board, convergence data needs to be uploaded to a computer via a chipper checker.  Because a full convergence is quite difficult.

SOURCE: NO POWER AT POWER SUPPLY BOARD EVEN AFTER REPLACING FUSE.

If the mains cord has only 2 pin plug, you can plug it the other way to see if the mains cord has an open circuit at one of the wires. It is not uncommon to find open circuited mains cord for a large appliance like a TV. The degaussing circuit causes a surge in current consumption when you switch on the TV from cold.

You hot is part of the HV Generator. One piece. must change the whole generator. The resistors are there, if you dont know where to put them, you have no business trying to monkey with a $2000 tv when electronics veterans like myself put food on our tables by repairng sets. Another point, if you are not trained on proper ESD handleing precautions, your only going to damage more chips and you will end up paying more for a real tech to fix it, IF THEY WILL EVEN TOUCH IT AFTER YOU HAVE BEEN IN IT.

SOURCE: My KP-65xbr10w appears dead no life when plugged in.

If you have no indication of power you may have lost all of the voltages to your power supply, including the 5 VDC standby voltage. I am not sure if you can get a new G board, but you should be able to get the individual components that you need. I would look for the cause of the power supply failure first, and I think I would look at your Horzontal Output Transistor. I am thinking it is Q501, Q401 or something like that. I have repaired many of these and the HOT is most likely the problem. A shorted HOT would cause the power supply fusables to blow and the entire set would appear to be dead.

I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.

SOURCE: Magnavox FP5210 W104 was watching fell asleep woke

I had a similar problem with my 42 in Philips LCD HDTV.


Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.


Here are some options for you.


1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)


2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found at tv-part.com but supplies are limited. I would definitely shop around though.


3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps kits can be bought online ,are inexpensive and, if you can take care of it yourself it will save you hundreds.


This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.


Hope this helps and if it does please rate it accordingly. Good luck.

PHILIPS 46 IN REAR PROJECTION ---- no picture, chirping


The power supply section is not working.
Common possibilities are:
- Convergences amps have failed overloading the supply
- High-voltage section (flyback transformer) has failed
(happens sooner or later, about 8 years typical))
- CRT tube has failed overloading the supply
- Power surge has popped the power input circuit.
(Fuse, rectifier diodes, turn-on relay etc)
- One of a hundred of electrolytic capacitors has failed short overloading the supply. They dry out with age, are cheap to replace, but hard to find which one it is,and it is caused of chirping sound....

RCA, CRT Projection TV, ITC222 chassis Faults - models D52W.., D40W.., D56W.., D61W..
· Symptom: No Convergence, Picture is bowed and distorted, colors don’t align.
The Fuse for the convergence power supply has blown
You'll also notice that the convergence settings have disappeared from the on screen menu. The fuse likely blew because of a fault on the convergence board. If you've never done soldering or dismantled a TV before this is probably not the best place to start. The back cover needs to be removed and the fuse (see picture) identified, the deflection/power supply board needs to be unplugged (label or mark all connectors beforehand) and flipped over and the fuse checked/replaced. You need a soldering iron and solder ****** or solder wick and a multi-meter to check the fuse. If you want to tackle it yourself see attached image for reference or get a quote from a repair shop (approx $200-$300 Total) the convergence board may also need repair.



  • Symptom: Dead Set - TV Tries to Start or intermittent dead.

The set could be in shut down mode due to a fault detected in the power supply, vertical or horizontal deflection circuits.
The common problems with this chassis that will cause a dead set or intermittent dead set symptom are, bad power supply capacitors, bad flyback, bad HV cap in horizontal output circuit and cold solders (on opposite side of board) especially under the flyback area. To gain access to replace any of these parts the back cover needs to be removed and the deflection/power supply board needs to be unplugged (label or mark all connectors beforehand) and flipped over.
These are only the most common problems and it could be any number of other faults.
If you have electronic (TV) repair experience check the items mentioned (see picture), otherwise it's best to seek a qualified RCA tech for an estimate/service call.

· Symptom: Erratic operation of set – turns off by self, the volume or channel changes by self or on screen menu appears intermittently.

Switches on the front panel assembly (FPA) problem.
What happens with this model is the FPA switches (one or more) start to conduct just as if someone was pressing the buttons. This in effect locks up the system control or causes it to initiate erratic commands.
The way to determine if the FPA is bad is to remove it by unplugging from set. This requires front panel disassembly.
Note: The remote will still work with the FPA removed so the set can be tested.

Hope this helped, johnnydiode, Fixya.

Blinking blue light on my philips 60pl9200d/37


I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.6_7_2012_5_03_18_pm.jpg6_7_2012_5_03_35_pm.jpg

Philips 60pp9202 has volume but no picture


You may a bad ground on the power supply board,and this may include a vertical IC that is having problems. Another thing for me to suspect would be the convergence board is on the fritz. At night sometime remove the back cover and see if you can see the ends of the picture tubes are lit while the TV is on. If they are I would say,yes the convergence ICs are bad. And finally , you may a bad small signal board. This is a small card next to the RCA connections and RF connectors inside this TV. This small signal card is quite expensive to replace. Also, this is my first calculation of errors on this unit. The last answer is my best guess. You will have to decide if you really want to repair this. Once again this small signal board is expensive. Thanks for asking and show a few hands of support.

Dead set


you can look at the capacitors on the power board if any of them have puffed up tops that is the ones. Also when you are looking at the power supply look under the heat sink at the top right they try to hide one.

No picture, no sound. sounds like a bird cherping in back of tv.


power supply wont come up, so it chips. the fuses are super hard to check on this one, but you can pull the cable that goes to convergence sometimes and it will come up with a bowed picture. its the 3rd ribbon cable going from the defleciton board (lots of high power parts) to the signal board (lots of daughter boards, small parts) there are 3 cables hooking the two together, pull the one furthest from the back and try to power on. be ready to pull the plug but it will come up and run with a bowed pict if the ICs are bad. if so, see this link for tips

Pull chassis--check all fuses,esp, F850 & F851.They protect
the B+ supplied to convergence circuit.They are found in the power
supply,on edge of the main board.On the signal board,locate the
large IC's mounted to heatsinks.IC part #  STK392-110.Between the
edge of the signal board and the IC's---locate two grey jumper wires
and some hard wire jumpers = solder them all,if you don't,the fuse may blow again.Next,replace IC's with Hitachi up-grade part
# STK394-160E....Reassemble...power on.....touch magic focus
and you are done....T.     ?????s-----Let me know...
