Hi! I am experiencing the following three


Hi Rafael,

First of all thank you for posting your question here at Fixya.
Please confirm if the brand and model number above is correct.
Blinking of the the LED (yellow and blue) at the front panel indicating that the lamp door cover is not seated properly. This cover will engaged to a micro switch giving the signal to the processor, once it is in open position, the unit will not power up and will experienced that kind of blinking error code. Go back to the lamp door cover and ensure that it is properly seat-in.
3D, 2D, red/green/blue ghost on the picture and letters means that the convergence circuitry gone bad. Symptoms is not connected to the light engine. The faulty parts is the convergence chips(IC). This chips are mounted on the large aluminum heat sink and starts with STKXXXX-XX (X means number). The most common STK chips used on Projection TV's is the STK392-110. You have to replaced them both on the board to resolve the issue(red ghosting). It is necessary also to check the resistance value of the resistors around its circuitry using the multimeter. For more info how to repair a convergence problem, watch the video below.

Tv turns off (both video and sound) after running for 20 sec and then turns on after 20 sec. This pattern continues over and over. None of the lights are blinking. Lamp is less than 2 yrs old and is...


Hi,
TV will show Lamp Light warning if lamp got broken or dead.
Symptoms of TV shows lamp is weak and will be replaced. Weak lamp consume more current than allowed ratings and causing activation of protection circuit that shuts off TV and TV turns on again itself, that is why no blinking red light.
Please replace lamp in your Sony KDF-E55A20 TV, lamp replacement procedure is easy and written in user manual, click Sony Support to download user manual copy, if required.
Always buy Sony original lamp for TV safety, Sony original lamp is available in Sony Accessories Store for $200 with following part number..
A1085447A... LAMP BLOCK ASSY XL-2200U
Hope this info will help you.
Thanks.

My Sony KP-46WT500 screen shows the tv image in blue only for a few seconds, then it goes completely blank (as if it were off). Do I need to replace the bulbs?


It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.

Problem with a colour display on Hisense tv


If your picures are all purple it means that the green colour is missing. TV colour is made up by mixing Red, Green & Blue. Removing Green leaving Red & Blue makes purple. Study the green colour circuit for a fault and confirm that the green gun inside the tube is working.

Light blinks like it wants to come on then 2 red lights blinks under the blue lighttemp and lamp are red lights tv want come on


Without the model number, I can't provide any details, but you should be able to look this up in the owner's manual. Usually blinking lights like this indicate a bad lamp, bad fan or something similar. The owner's manual will have a chart that shows what the indicators mean. If you can not find the manual, please post the model number and I'll look for one.

Thanks,
Dan

Toshiba TP43H95 projection tv has power but no picture


If it shuts off and then the power light starts blinking red or it never comes on but the power light just blinks red continuously that is usually indicative of the convergence ICs (STK 392-110). You never want to replace the ICs without also replacing the resistors that are associated with them. There are usually 6 resistors, one for each of the colors and there corresponding direction, IE Red horizontal, red vertical, blue horizontal, ect. In the case of this model tv all of the resistors are 2.2 Ohm and 2watts. You will find them right where the STK 392-110 ICs are. Right in front of them. They are blue and have this color code on them. Red, red, gold, gold. These are represented by stripes on the resistors. You can get the parts from www.bdent.com They carry the ICs and the resistors. If you do not feel comfortable completing this repair I could do it for you if you send me the board. My email address is: missionelectronics@sbcglobal.net The cost is 375.00 and that includes parts.
Good Luck.
