Question about Toshiba 43H71 43" Rear Projection Television

1 Answer

Blue ghost When the tv is on there is what I would call a blue ghost in the picture. It seems that the blue projection lens is off set. When I run the touch focus, the green and red lines are straight but the blue lines are curvey. At the end of the touch focus it says "touch focus error". How can I correct this problem?

Re: blue ghost

If you have the ability to work on solid state electronics and know how these circuits work, you will need to replace the convergence IC's in this TV set. If you do not, call in a pro to assist you in this repair. Good Luck

I took the back of the tv off and the blue lamp is not bright like the red and green. Could this be a coolant problem or lamp. I have the PT5492S Akai rear projection TV.

The blue is usually dimmer than the other two lens; what I would suggest is try to look into the lens with the set on; BE CAREFUL AND NOT TOUCH ANYTHING INSIDE THE SET.

If the red and green show a picture but the blue looks like a floodlight you have bad Glycol in the blue tube (common in these sets).

If all have a normal picture remember to wipe the lens clean at the top; do not try to take the lens etc apart.

Before you rate this information let me know what you find.

If the ghosting is like a 3D effect its your convergence ICs , but if its like a blue Halo around objects that usually means your CRT coolant has congealed and will need replacement. The blue is the first tube to congeal for some reason, followed by green. Red seems to be not quite as prone to this. It is a normal occurrence n sets about 4 years old to need the coolant changed.

I have blue ghosting in our TV picture

if the picture looks kinda 3-D
Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";} The best advice I can tell you at this point is to go to and order the complete convergence kit for your model of TV set, no need to search and order multiple parts from different sources and pay multiple shipping fees! The kit comes with original Sanyo STK IC’S , not those cheap aftermarket or china made IC’S full pictorial directions, the thermal paste, resistors, the correct Pico fuses, AND free live on-Line tech assistance in case you run into a problem with the repair. They ship out 2 to 3 day Priority mail, the next day in most cases you may need to open the set and tell them what the STK numbers are on the chipsGOOD LUCK!!!

Hi , audio output failure, possibly needs re-boot of cable/sat system, too many variables to troubleshoot on here, and thats generally a great tv so yes I would advise you to get a tech to fix it, video-tek

Problem with HD feed from satellite receiver

I just had my HD DTV installed this weekend, you have to leave it on 480p. I too purchased my tv in 2002. Per DTV, its an older model and you have to stay with the 480p to get the best possible picture. I have to admit, don't know what the 1080i looks like, but 480p is showing me a very good picture. Best I have ever seen on my TV.
