Panasonic PT-53TW53 53" Rear Projection HDTV-Ready Television - Page 6 - Answered Questions & Fixed issues

Ur backlight IC inverter board is lose connections or it dead.Take it aparts and see,properally the dead board usally is.Tries this Website.Tv Repair World.com.Type in ur tv name & model parts number u can buy it and replace it.Or ask questions or intructions.

This is a very common problem with all projection tv's it is the stk392 ic's in your set have failed. You can attempt the repair yourself as long as you understand the risks involved when working inside a tv, otherwise you can get it repaired by a pro and i would guesstimate it will cost somwhere between 250 to 300 to fix. the ic's are located on a big heatsink and the number stk392-xxx xxx If xxx is beteween the numbers 110 and 180 you can use the stk392-180 for the repair, and i would recomment doing this. if it is stk392-560 or another number replace only with the same ic.

I have green convergence not align after replacing both Ics. Please help

Bad IC is my guess...

On anotehr note convergence is a very common failure on Projection TV sets.

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.

You can see some example photos and find a solution here...

lo que puede hacer es medir el ohm de la resistencia y * 2 pero desde el terminal hasta la mitad de la resistencia

Your symptoms sounds like a damaged convergence IC.

There are two and large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110, and they are located on the signal board (on the left as you look into the back of the set).

What happens in the Panasonic set is that the convergence IC’s will short and cause the power supply to shut down from the overload of current. This is indicated by the flashing red light on the front of the set.
Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.
There are also two resistors on the front of the board located in the middle that are fusible link resistors, these should be checked for opens and replaced if they are found so.

I would suggest that you contact a service center in your area for a complete diagnosis and repair, as this type of repair can get a little tricky. But if you want to repair the set yourself, just remember to be careful. The capacitors and CRT’s can hold a charge and may shock you.


If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.

I hope this information allows you to resolve this issue.

Thats the error code for the convergence. You can get the PT53WX53 Convergence repair kit at the following link. www.tvrepairworld.com
the kit contains the parts and CD with instructions

Hi,

This a problem when the electrolytic capacitors of the hardware on the monitor goes of. Either you can try replacing these capacitor or you can take it to a repair person.


Thanks

what color is out of alignment?

You would have to remove the back of the television board and there should be a black plastic piece that covers and protects the bulb inside the television. I would recommend that if you are not a technician please have an experienced person replace your bulb.

that sounds like a very expensive repair I'm afraid
, it is the light engine that is bad

You can get complete convergence kits from www.TvRepairKits.com

If it is hot were you live this could be the problem. these units don't like temp. about 32 Celsius.

check for defective C945 transistors and diode

I would not do it, I had this issue before and the fix only lasted a few months then it happened again, sorry

unplug for two hours and try it again. if that doesnt fix powersupply is probably going bad.

In almost all cases a three blink code on that model indicates a convergence output failure. Those big amplifier IC's need to be replaced.

Indicates lamp , check air filters and replace lamp

i have a philips tv model # 55pw9363/17f have sound no pic

get a converter box, or change it, don't be OCD it is simple
