Ben, Sorry, no exact findings, but these may give you a start....HTH GL "joe" ================================= Mits PTV model VS45VA2 problem-This Mits PTV model VS45VA2, has intermittent sync problems. It seems to be quite sensitive around DL205
On bottom of signal pcb between IC201 & connector Rh, there is white silicone glue. Remove glue and resolder the component under it. ================================= Mits vs4543 This set has small black and white lines similar to Venican blinds floating across the picture vertically .Similar to Jail bars only going side ways. Scope the 9 volt line for ripple. If it is there, replace the filter caps off the regulator. Scope all the power supply and scan supplies for ripple. See if this set has a C281 (100mfd/16V). If so, replace it. ================================= Mitsubishi VS-5062 projection TV The picture rolls constantly via cable, antenna.and line in inputs. The menu does not roll.� I found a leaking cap C-526 on the main pcb near the v-height,v-lin and hv reg pots. On darker pictures the rolling would stop as when a commercial is fading out and is worse with a bright picture.� ================================== Mitsubishi vs6087 projection TV with vertical jitter.Twice in the past 6 months the tv has been serviced after the installation of a vertical jitter kit v14vj.� The basic curcuit is not stable and the kit has not solved the stability problem. Check if the set has the small plugin pip pcb.� If it does change C-7001 on the pcb and check for damage to the traces from the electrolyte from that smd cap. ================================== Mitsubishi VS-5007R projection TV has no vertical deflection. Replaced Vert-output IC and caps in that circuit, but still no vertical defection. Check R540, a 1 ohm resistor off the flyback.Check the supplies to the vertical ckt. Derived from the FBT, etc. Also check connections to/from yokes. ================================== [EMAIL PROTECTED] From: [EMAIL PROTECTED] (ben�daniels) Date: Mon, Jan 12, 2004, 10:27am (EST-3) To: [EMAIL PROTECTED] (Posts) Subject: [Techs] Mits. Mod: VS4007R Rolls at channel change Reply�to: [EMAIL PROTECTED] (ELECTRONICS PROFESSIONALS LIST) This unit will roll when you change channels and verticle is unstable will tear alittle. The menu is stable. Looks like pip is bad but this doesn't have it. I am sure bad caps but thought someone might have a tip already. Thanks Ben __________________________________ Do you Yahoo!?
